DRV590DWP Equivalent & Substitute Parts

Part Overview

The DRV590DWP is a thermoelectric cooler PMIC manufactured by Texas Instruments in a 20-SOIC package with exposed pad. This device functions as an IC PWM power driver optimized for high-efficiency thermoelectric cooler applications. The DRV590DWP is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity. Substitute parts must maintain compatibility with the original supply voltage range, operating temperature specifications, and thermoelectric cooler application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DRV590DWP are identified based on the following criteria:

Primary Substitution Parameters:

• Manufacturer: Texas Instruments (same manufacturer family)
• Application: Thermoelectric cooler PMIC functionality
• Operating Temperature Range: -40°C ~ 85°C (matching specification)
• RoHS Compliance: ROHS3 Compliant (regulatory alignment)
• Supply Voltage Compatibility: Overlapping or compatible voltage ranges

Substitute Classification:

The four identified substitutes (DRV591VFP, DRV593VFP, DRV594VFP, DRV595DAP) represent active product alternatives within the Texas Instruments DRV59x family. DRV591VFP, DRV593VFP, and DRV594VFP are packaged in 32-HLQFP (7x7) format with thermoelectric cooler application focus and supply voltage range of 2.8V ~ 5.5V. DRV595DAP operates in a different application domain (PWM Power Driver) with extended supply voltage range (4.5V ~ 26V) and is packaged in 32-HTSSOP format.

Engineering Selection Recommendations

For Thermoelectric Cooler Applications (Primary Use Case):

DRV591VFP, DRV593VFP, and DRV594VFP are direct functional alternatives to the DRV590DWP. All three are active products with ROHS3 compliance and matching operating temperature specifications. DRV594VFP offers the highest inventory availability (32,400 units) and maintains the same supply voltage range compatibility (2.8V ~ 5.5V minimum overlaps with DRV590DWP's 2.7V floor). DRV593VFP and DRV594VFP both specify 4mA supply current, closely aligned with the DRV590DWP's 4.5mA specification.

For Extended Supply Voltage Applications:

DRV595DAP operates across a wider supply voltage range (4.5V ~ 26V) and is classified as a PWM Power Driver rather than a thermoelectric cooler PMIC. This part is suitable only for applications where the extended voltage capability is required and the design can accommodate the 32-HTSSOP package format and higher supply current (50mA).

Package Considerations:

The DRV590DWP uses a 20-SOIC package. All substitute parts employ larger pin-count packages (32-pin LQFP or HTSSOP), requiring PCB layout redesign. DRV591VFP, DRV593VFP, and DRV594VFP use identical 32-HLQFP (7x7) packaging, simplifying cross-substitution within this subset.

Frequently Asked Questions (FAQ)

Q: Can DRV591VFP, DRV593VFP, or DRV594VFP directly replace DRV590DWP without PCB modification?

A: No. The DRV590DWP uses a 20-pin SOIC package, while all three substitutes use 32-pin LQFP packages. PCB layout redesign is required, including pin mapping, trace routing, and thermal management adjustments.

Q: Which substitute part is recommended for new thermoelectric cooler designs?

A: DRV594VFP is recommended based on active product status, high inventory availability (32,400 units), ROHS3 compliance, matching operating temperature range (-40°C ~ 85°C), and supply current specification (4mA) aligned with the original DRV590DWP (4.5mA).

Q: Is DRV595DAP suitable for thermoelectric cooler applications?

A: DRV595DAP is classified as a PWM Power Driver with extended supply voltage range (4.5V ~ 26V) and higher supply current (50mA). It is suitable only for applications requiring this extended voltage capability and can accommodate the different package format and electrical characteristics.

Q: What is the minimum supply voltage compatibility between DRV590DWP and its substitutes?

A: DRV590DWP operates from 2.7V minimum. DRV591VFP, DRV593VFP, and DRV594VFP operate from 2.8V minimum, representing a 0.1V difference. DRV595DAP requires 4.5V minimum, limiting compatibility to higher-voltage applications only.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DRV591VFP, DRV593VFP, DRV594VFP, and DRV595DAP are all ROHS3 compliant, matching the regulatory status of the obsolete DRV590DWP.

Q: What is the difference in Moisture Sensitivity Level (MSL) between parts?

A: DRV590DWP, DRV593VFP, and DRV594VFP specify MSL 2 (1 Year). DRV591VFP and DRV595DAP specify MSL 3 (168 Hours), requiring more stringent moisture control during storage and handling.
