Texas Instruments DRV8935PRGER

Overview

DRV8935PRGER from Texas Instruments is a quad half-bridge driver IC designed for industrial motor and solenoid control. It delivers up to 2.5-A peak current per channel, operates from 4.5 V to 33 V, features integrated current sensing with programmable trip via VREF12/VREF34 pins, and supports configurable PWM off-times of 7/16/24/32 μs. It drives four solenoids, two DC motors, or one stepper motor in compact VQFN-24 packaging.

For engineers reviewing the DRV8935PRGER datasheet, DRV8935PRGER pinout, DRV8935PRGER application, or DRV8935PRGER equivalent, key selection considerations include its 2.5-A per-channel drive capability, dual independent current regulation (VREF12/VREF34), spread-spectrum EMI reduction, 2-μA sleep current, and fault reporting via open-drain nFAULT.

Technical Context

The DRV8935PRGER integrates four independent N-channel half-bridge output stages, each with high-side and low-side MOSFETs (RDS(ON) = 165 mΩ HS + 165 mΩ LS at 25°C). Current regulation uses transimpedance gain KV = 1.32 V/A to convert VREF voltage into ITRIP, enabling precise per-pair (OUT1/OUT2 and OUT3/OUT4) current limiting.

It employs a fixed-frequency charge pump (360 kHz) to generate gate drive for high-side N-FETs, supports 1.8-V/3.3-V/5.0-V logic inputs with internal pulldowns, and implements protection including VM UVLO (4.25 V threshold), VCP undervoltage detection, cycle-by-cycle OCP (4-A trip), and thermal shutdown (150°C TJ).

FAQ

What is the maximum continuous output current per channel for the DRV8935PRGER?

The DRV8935PRGER supports up to 2.5-A peak output current per channel at 24 V and 25°C. Its RMS current capability is 1.75 A per channel, dependent on PCB thermal design and ambient conditions. This rating is validated under recommended operating conditions with proper heatsinking via the exposed thermal pad. The DRV8935PRGER includes overcurrent protection that disables the affected half-bridge if current exceeds 4 A for longer than 1.8 µs.

How does the DRV8935PRGER implement current regulation without external sense resistors?

The DRV8935PRGER uses integrated current-sense MOSFETs and a transimpedance amplifier with gain KV = 1.32 V/A. The user applies a reference voltage (0.05–3.3 V) to VREF12 or VREF34, and the device calculates ITRIP = VREF / 1.32. This eliminates external shunt resistors and op-amps while maintaining ±5% accuracy across temperature. The DRV8935PRGER automatically adjusts duty cycle during PWM off-time to maintain this regulated current.

Can the DRV8935PRGER drive a bipolar stepper motor, and how is it configured?

Yes, the DRV8935PRGER can drive a bipolar stepper motor by configuring two half-bridges as one full H-bridge per phase. Connect OUT1/OUT2 to phase A and OUT3/OUT4 to phase B. Control sequencing is performed externally via IN1–IN4 with standard step/direction logic. The DRV8935PRGER's integrated current regulation maintains consistent torque across speed ranges, and its 40-kHz PWM support enables smooth microstepping without external chopper ICs.

What protection features are built into the DRV8935PRGER, and how are faults reported?

The DRV8935PRGER includes VM undervoltage lockout (UVLO), charge pump undervoltage (CPUV), overcurrent protection (OCP), and thermal shutdown (OTSD). All faults assert the open-drain nFAULT pin low. UVLO and OTSD are latched and require an nSLEEP reset pulse (20–40 µs); CPUV and OCP recover automatically once the condition clears. The DRV8935PRGER provides distinct fault recovery behaviors documented in Table 7-3 of its datasheet.

Is the DRV8935PRGER pin-compatible with other devices in the DRV89xx family?

The DRV8935PRGER shares the same VQFN-24 (RGE) footprint and pinout with the DRV8955RGER, enabling drop-in replacement for 48-V systems. However, it is not pin-compatible with the HTSSOP-28 DRV8935PPWPR variant. While functionally similar to DRV8932PWPR, the latter uses HTSSOP-28 packaging and lacks spread-spectrum EMI control - confirming that DRV8935PRGER's VQFN-24 layout is unique to its 33-V, low-EMI, low-power feature set.
