TPIC9201N Equivalent & Substitute Parts

Part Overview

The TPIC9201N is a Power Management IC (PMIC) classified as a Power Switch/Driver with 1:8 N-Channel configuration, rated for 150mA output current. Manufactured by Texas Instruments, this component operates with a load voltage range of 7V to 18V and supply voltage of 0V to 5.25V. The device features current limiting and over-temperature fault protection, with an operating temperature range of -40°C to 125°C.

The TPIC9201N is marked as Obsolete, making equivalent and substitute parts necessary for ongoing system support and new procurement. Substitute parts must maintain functional equivalence across critical electrical parameters while accommodating different packaging and mounting technologies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TPIC9201N are evaluated based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Number of Outputs: 8 channels required
• Ratio - Input:Output: 1:8 configuration
• Output Configuration: Low Side switching
• Interface: Serial control capability
• Voltage - Load: Operating range 7V ~ 18V
• Voltage - Supply: Operating range 0V ~ 5.25V
• Current - Output (Max): Minimum 150mA per channel
• Fault Protection: Current Limiting and Over Temperature protection
• Operating Temperature: -40°C ~ 125°C range

Secondary Considerations:

• Mounting Type: Through Hole vs. Surface Mount (affects PCB layout compatibility)
• Package / Case: Physical footprint and pin compatibility
• Product Status: Active vs. Not For New Designs vs. Obsolete
• RoHS and Compliance Status: ROHS3 Compliant required

Substitutes are grouped by their adherence to these criteria. Parts maintaining identical electrical specifications across all primary criteria are considered direct functional equivalents, regardless of packaging differences.

Parameter Comparison

Engineering Selection Recommendations

TPIC9201PWPR (Texas Instruments): This part maintains identical electrical specifications to the TPIC9201N across all primary substitution criteria, including 1:8 N-Channel configuration, 150mA output current, 7V-18V load voltage, and 0V-5.25V supply voltage. The primary difference is packaging: TPIC9201PWPR uses 20-PowerTSSOP surface mount technology versus the through-hole 20-DIP of the original. Product status is listed as Not For New Designs. This substitute is suitable for direct functional replacement where PCB layout can accommodate surface mount conversion.

MIC59P60YN (Microchip Technology): This part provides 1:8 output configuration with 8 channels in low-side configuration, matching the TPIC9201N topology. However, the output type is Bipolar rather than N-Channel, and maximum output current is 500mA, exceeding the original 150mA specification. Load voltage range is restricted to 5V-12V, which does not fully cover the original 7V-18V range. Operating temperature maximum is 85°C versus 125°C for the original. This part is Active status and maintains through-hole 20-DIP packaging. Substitution is limited to applications where the reduced temperature range and restricted load voltage are acceptable.

Z8523316VSG (Zilog): This part is classified as Interface rather than Power Management (PMIC) and lacks specified electrical parameters for output configuration, number of outputs, output type, and current rating. The 44-PLCC package is incompatible with the 20-DIP footprint of the original. Insufficient technical data prevents confirmation of functional equivalence. This part is not recommended as a substitute.

Frequently Asked Questions (FAQ)

Q: Can TPIC9201PWPR be used as a direct replacement for TPIC9201N?

A: TPIC9201PWPR is electrically equivalent to TPIC9201N across all primary specifications: 1:8 N-Channel configuration, 150mA output current, 7V-18V load voltage, and 0V-5.25V supply voltage. The primary difference is packaging: TPIC9201PWPR uses surface mount 20-PowerTSSOP versus through-hole 20-DIP. Direct PCB replacement requires layout modification to accommodate the different package footprint and pin pitch.

Q: Is MIC59P60YN a suitable substitute?

A: MIC59P60YN shares the 1:8 output configuration and low-side topology but differs in critical specifications. The Bipolar output type differs from the N-Channel of the original. Maximum output current is 500mA versus 150mA, and load voltage range is limited to 5V-12V instead of 7V-18V. Operating temperature maximum is 85°C versus 125°C. Substitution is only viable for applications where these parameter differences are compatible with system requirements.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: (1) Number of Outputs (8 required), (2) Ratio - Input:Output (1:8 required), (3) Output Configuration (Low Side required), (4) Output Type (N-Channel preferred), (5) Voltage - Load range (7V-18V minimum), (6) Voltage - Supply range (0V-5.25V minimum), (7) Current - Output (150mA minimum), and (8) Fault Protection (Current Limiting and Over Temperature required). Packaging and mounting type are secondary considerations affecting PCB layout compatibility.

Q: Why is Z8523316VSG not recommended as a substitute?

A: Z8523316VSG is classified as an Interface component rather than a Power Management PMIC. Critical electrical parameters including number of outputs, output configuration, output type, and current rating are not specified in available data. The 44-PLCC package is physically incompatible with the 20-DIP footprint. Insufficient technical documentation prevents confirmation of functional equivalence to the TPIC9201N.

Q: What is the impact of switching from through-hole to surface mount packaging?

A: Switching from 20-DIP through-hole (TPIC9201N) to 20-PowerTSSOP surface mount (TPIC9201PWPR) requires PCB redesign. Surface mount technology offers reduced board space and improved thermal characteristics but requires different assembly processes and equipment. Pin pitch and package dimensions differ significantly, necessitating layout modifications. Electrical functionality remains identical.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts (TPIC9201PWPR, MIC59P60YN, and Z8523316VSG) are ROHS3 Compliant, matching the compliance status of the original TPIC9201N.
