DRV84x2 Dual Full-Bridge PWM Motor Driver

The DRV841x2 requires two power supplies, one at

1 Features

12 V for GVDD and VDD, and another up to 50 V for

PVDD. The DRV841x2 can operate at up to 500-kHz

switching frequency while still maintaining precise

control and high efficiency. The devices also have an

innovative protection system safeguarding the device

against a wide range of fault conditions that could

damage the system. These safeguards are short-

circuit protection, overcurrent protection, undervoltage

protection, and two-stage thermal protection. The

DRV841x2 has a current-limiting circuit that prevents

device shutdown during load transients such as motor

start-up. A programmable overcurrent detector allows

adjustable current limit and protection level to meet

different motor requirements.

•

High-Efficiency Power Stage (up to 97%) With

Low R_DS(on)MOSFETs (110 mΩ at T_J= 25°C)

•

Operating Supply Voltage up to 52 V

DRV8412 (Power Pad Down): up to 2 × 3-A

Continuous Output Current (2 × 6-A Peak) in Dual

Full-Bridge Mode or 6-A Continuous Current in

Parallel Mode (12-A Peak)

•

DRV8432 (Power Pad Up): up to 2 × 7-A

Continuous Output Current (2 × 12-A Peak) in

Dual Full-Bridge Mode or 14-A Continuous

Current in Parallel Mode (24-A Peak)

•

PWM Operating Frequency up to 500 kHz

The DRV841x2 has unique independent supply and

ground pins for each half-bridge. These pins make it

possible to provide current measurement through

external shunt resistor and support multiple motors

with different power supply voltage requirements.

3 Description

The DRV841x2 are high-performance, integrated dual

full-bridge motor driver with an advanced protection

system.

PWM_C

RESET_CD

Because of the low R_DS(on)of the H-Bridge MOSFETs

and intelligent gate drive design, the efficiency of

these motor drivers can be up to 97%. This high

efficiency enables the use of smaller power supplies

and heatsinks, and the devices are good candidates

for energy-efficient applications.
