Texas Instruments DRV8935PPWPR

Overview

DRV8935PPWPR from Texas Instruments is a quad half-bridge motor driver IC designed for industrial load control, integrating four independent N-channel MOSFET half-bridges with on-chip current sensing and regulation. It delivers up to 2.5-A peak per channel at 24 V, operates from 4.5 V to 33 V, features configurable PWM off-time (7/16/24/32 μs), and supports 1.8-V/3.3-V/5.0-V logic inputs - enabling direct interface with microcontrollers in refrigerator damper, textile machine, and factory automation systems.

For engineers reviewing the DRV8935PPWPR datasheet, DRV8935PPWPR pinout, DRV8935PPWPR application, or DRV8935PPWPR equivalent, key selection considerations include its integrated current regulation via dual VREF pins (VREF12/VREF34), thermal shutdown and overcurrent protection with latched fault reporting on nFAULT, HTSSOP-28 package thermal performance (RθJA = 31.0°C/W), and compatibility with solenoid, DC motor, and stepper motor topologies requiring precise current-controlled drive.

Technical Context

The DRV8935PPWPR implements fixed off-time current chopping across all four half-bridges, where ITRIP is set by external voltage on VREF12 (channels 1–2) or VREF34 (channels 3–4) using transimpedance gain of 1.32 V/A. Each channel uses independent high-side and low-side N-MOSFETs with RDS(ON) of 165 mΩ (HS) + 165 mΩ (LS) at 25°C, enabling efficient 2.5-A peak drive into inductive loads connected to VM.

Control is executed via four dedicated INx pins with internal pulldowns, supporting simple PWM interface; TOFF pin selects one of four discrete off-times; nSLEEP enables 2-μA sleep mode with 120-μs entry and 1.2-ms wake-up; and nFAULT provides open-drain fault signaling for UVLO, CPUV, OCP, and OTSD events - all managed without external timing components.

Key Specifications

Pinout & Package

DRV8935PPWPR is housed in a thermally enhanced HTSSOP-28 (PWP) package measuring 9.7 mm × 4.4 mm with exposed PowerPAD™ for PCB-level heat dissipation. The package supports RθJA = 31.0°C/W and RθJB = 10.8°C/W when properly soldered to a 2-layer board with thermal vias.

FAQ

What is the maximum continuous output current per channel for the DRV8935PPWPR?

The DRV8935PPWPR supports up to 2.5-A peak output current per channel at 24 V and 25°C. Its continuous RMS current capability is 1.75 A per channel, dependent on PCB thermal design - verified under recommended operating conditions with adequate copper area and thermal vias to the exposed PowerPAD™.

How does current regulation work on the DRV8935PPWPR?

Current regulation on the DRV8935PPWPR is implemented via two reference pins: VREF12 sets ITRIP for channels 1 and 2, and VREF34 sets ITRIP for channels 3 and 4. The relationship is ITRIP (A) = VREF (V) / 1.32 V/A. For example, applying 1.32 V to VREF12 configures 1-A trip current for OUT1 and OUT2 - enabling independent current limiting for mixed-load configurations.

What package type and thermal characteristics does the DRV8935PPWPR use?

The DRV8935PPWPR uses the HTSSOP-28 (PWP) package with 9.7 mm × 4.4 mm body size and an exposed thermal PowerPAD™. Its thermal metrics include RθJA = 31.0°C/W and RθJB = 10.8°C/W on a 2-layer board - significantly better than VQFN alternatives - making it ideal for high-power density industrial modules where airflow is limited.

Can the DRV8935PPWPR drive a stepper motor, and how is it configured?

Yes, the DRV8935PPWPR can drive a bipolar stepper motor by pairing its four half-bridges as two full H-bridges (e.g., OUT1/OUT2 for phase A, OUT3/OUT4 for phase B). Direction and microstepping are controlled via coordinated PWM on IN1–IN4, while VREF12 and VREF34 independently set phase current limits - supporting up to 1.75-A RMS per phase without external current-sense components.

What fault conditions does the nFAULT pin indicate on the DRV8935PPWPR?

The nFAULT pin on the DRV8935PPWPR indicates four latched fault conditions: VM undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP) on any FET, and thermal shutdown (OTSD). All faults pull nFAULT low and remain latched until cleared by a 20–40 μs nSLEEP reset pulse or full power cycle - ensuring robust system-level error handling in safety-critical applications.
