TMP816PWR Motor Driver IC - Equivalent & Substitute Parts

Part Overview

The TMP816PWR is an active production motor driver IC manufactured by Texas Instruments, designed for brushed DC motor speed control applications. This device operates across a 6V to 16V supply voltage range and features PWM interface control with a pre-driver half-bridge output configuration in a 20-TSSOP surface mount package. The part is ROHS3 compliant with unlimited moisture sensitivity rating, making it suitable for fan controller and similar motor control applications. Substitute parts are identified when equivalent electrical specifications, package compatibility, and functional characteristics align with the original design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TMP816PWR is determined by strict alignment of the following parameters:

• Motor control function (brushed DC speed controller)
• Output configuration (pre-driver half-bridge topology with 2 outputs)
• PWM interface requirement
• Supply voltage range (6V ~ 16V)
• Operating temperature range (-30°C ~ 95°C)
• Package specification (20-TSSOP with 0.173" width, 4.40mm)
• Surface mount mounting type
• RoHS3 compliance and MSL rating

The TMP814PWR meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the TMP816PWR and TMP814PWR are active production components from Texas Instruments with identical electrical specifications, package geometry, and compliance certifications. Selection between these parts is based on availability and supply chain requirements rather than functional differences. Both devices meet ROHS3 compliance and carry unlimited moisture sensitivity rating (MSL 1), suitable for standard manufacturing and storage conditions. PCB layout and design files require no modification when substituting between these parts, as pin configuration, package dimensions, and electrical characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can TMP814PWR be used as a direct replacement for TMP816PWR in existing designs?

A: Yes. Both parts share identical electrical specifications, PWM interface requirements, supply voltage range (6V ~ 16V), operating temperature range (-30°C ~ 95°C), and 20-TSSOP package geometry. No design modifications are required.

Q: Are there any differences in pin configuration between these parts?

A: No differences exist. Both devices use the same 20-TSSOP package with identical pin assignments and functionality.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TMP816PWR and TMP814PWR are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is based on matching motor control function, output configuration (pre-driver half-bridge), PWM interface, supply voltage range, operating temperature range, package specification, mounting type, and compliance certifications. All these parameters must align exactly.

Q: Can these parts be used interchangeably in fan controller applications?

A: Yes. Both parts are specified for fan controller applications with brushed DC motor speed control and are functionally equivalent for this use case.
