DRV8332DKD Equivalent & Substitute Parts

Part Overview

The DRV8332DKD is a half bridge driver IC manufactured by Texas Instruments, designed for DC motor and general-purpose power MOSFET applications. This device integrates three half-bridge outputs with PWM interface control, delivering 8A continuous output current per channel and 13A peak output capability. The DRV8332DKD operates across a supply voltage range of 10.8V to 13.2V with load voltage support up to 52.5V, and includes comprehensive fault protection features including current limiting, over-temperature shutdown, short-circuit protection, and under-voltage lockout (UVLO).

The DRV8332DKD is currently in Last Time Buy status, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts are selected based on matching output configuration, fault protection architecture, and compatible electrical operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRV8332DKD are selected based on the following critical parameters that determine functional compatibility:

Primary Substitution Criteria:

• Output Configuration: Half Bridge (3) topology
• Fault Protection Architecture: Current Limiting, Over Temperature, Short Circuit, UVLO
• Technology: Power MOSFET
• Applications: DC Motors, General Purpose
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

Secondary Compatibility Factors:

• Voltage - Supply range compatibility with 10.8V ~ 13.2V
• Voltage - Load range compatibility with 0V ~ 52.5V
• Operating Temperature range overlap with -40°C ~ 150°C
• Interface type (PWM or Parallel control)
• Load type (Inductive)

Substitute parts are grouped into two categories based on their electrical performance characteristics relative to the main part:

Category 1 - Direct Current Rating Substitutes: Parts with output current ratings at or above 8A per channel, maintaining equivalent or superior performance envelope.

Category 2 - Reduced Current Rating Substitutes: Parts with output current ratings below 8A per channel, suitable for applications with lower current requirements or as cost-optimized alternatives.

Parameter Comparison

Engineering Selection Recommendations

DRV8332HDDV is the primary substitute for the DRV8332DKD within the same product family. Both devices share identical supply voltage (10.8V ~ 13.2V) and load voltage (0V ~ 52.5V) specifications, PWM interface control, and comprehensive fault protection architecture. The DRV8332HDDV maintains the same 80mOhm on-resistance characteristics and bootstrap circuit with status flag features. The primary trade-off is reduced output current (5A per channel versus 8A), which is acceptable for applications with lower current demands. The DRV8332HDDV operates across an extended temperature range (-55°C ~ 175°C) compared to the main part, providing superior thermal performance margin. This part is in Active product status with higher inventory availability (829 pcs) and improved moisture sensitivity rating (MSL 3 versus MSL 4).

DRV8312DDW provides an alternative within the DRV83xx family with further reduced output current (4.6A per channel). This part maintains identical supply and load voltage specifications, PWM interface, and fault protection features. The DRV8312DDW is suitable for lower-power DC motor applications and offers the same 80mOhm on-resistance as the main part. This device is in Active status with significantly higher inventory (7375 pcs) and improved moisture sensitivity (MSL 3).

DRV8313PWP and DRV8313RHH represent alternative architectures with expanded voltage operating range (8V ~ 60V supply and load). These parts employ Parallel interface control rather than PWM, and are optimized for brushless DC (BLDC) motor applications. The DRV8313 family does not specify discrete output current ratings per channel. These substitutes are suitable only for designs that can accommodate Parallel control interface and require the extended voltage operating range. The DRV8313RHH offers the highest inventory availability (88100 pcs) among all substitutes.

Selection Basis:

• All substitute parts maintain ROHS3 compliance and EAR99 export classification
• All parts are manufactured by Texas Instruments with established supply chain presence
• Product status transition from Last Time Buy (main part) to Active status (all substitutes) ensures long-term availability
• Moisture sensitivity improvements (MSL 4 to MSL 3) reduce handling and storage risk
• Package differences require PCB layout redesign; select based on available board space and thermal management requirements

Frequently Asked Questions (FAQ)

Q: Can DRV8332HDDV directly replace DRV8332DKD in existing designs?

A: DRV8332HDDV is functionally compatible for applications where 5A per channel output current is sufficient. The reduced current rating is the primary limitation. Supply voltage, load voltage, fault protection, and control interface are identical. PCB layout modification is required due to different package types (44-HTSSOP versus 36-BSSOP).

Q: What is the key difference between DRV8312DDW and DRV8332HDDV?

A: Both parts share identical electrical specifications (supply voltage, load voltage, fault protection, PWM interface). The DRV8312DDW provides 4.6A per channel output current versus 5A for the DRV8332HDDV. Selection depends on application current requirements and cost optimization priorities.

Q: Are DRV8313PWP and DRV8313RHH suitable substitutes for the DRV8332DKD?

A: DRV8313 parts are functionally compatible only for applications that support Parallel control interface instead of PWM. These parts offer expanded voltage operating range (8V ~ 60V) suitable for BLDC motor applications. They are not direct replacements for PWM-based DC motor designs without control circuit redesign.

Q: What are the package considerations when selecting a substitute?

A: The main part uses 36-BSSOP (11.00mm width). DRV8332HDDV and DRV8312DDW use 44-HTSSOP (6.20mm width). DRV8313PWP uses 28-HTSSOP (4.40mm width). DRV8313RHH uses 36-VFQFN (6x6). Package selection impacts PCB footprint, thermal management, and board layout. Verify package compatibility with existing PCB design before substitution.

Q: Does the extended temperature range of DRV8332HDDV (-55°C ~ 175°C) provide advantages?

A: The extended temperature range provides design margin for applications operating at temperature extremes. The main part operates -40°C ~ 150°C. If your application operates within the main part's range, the extended range of DRV8332HDDV provides additional thermal headroom but is not required for compatibility.

Q: What is the impact of different on-resistance values?

A: DRV8332DKD and DRV8312DDW both specify 80mOhm on-resistance (LS and HS). DRV8332HDDV specifies 260mOhm on-resistance. Higher on-resistance increases power dissipation and heat generation. For equivalent current levels, the 80mOhm devices are preferred. For reduced current applications, the 260mOhm specification of DRV8332HDDV is acceptable.

Q: How does moisture sensitivity level (MSL) affect component handling?

A: DRV8332DKD is MSL 4 (72-hour floor life after moisture exposure). All substitute parts are MSL 3 (168-hour floor life). MSL 3 provides extended handling time and reduced risk of moisture-induced failures during assembly. Lower MSL ratings are advantageous for supply chain logistics and manufacturing processes.

Q: Can I use DRV8313RHH for high-volume production?

A: DRV8313RHH has the highest inventory availability (88100 pcs) among all substitutes, supporting high-volume production requirements. However, this part requires Parallel control interface and operates across 8V ~ 60V range. Verify that your design supports these specifications before committing to high-volume production.
