Dual Full Bridge PWM Motor Driver

Check for Samples: DRV8412 DRV8422 DRV8432

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

FEATURES

and intelligent gate drive design, the efficiency of

these motor drivers can be up to 97%, which enables

the use of smaller power supplies and heatsinks, and

are good candidates for energy efficient applications.

•

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

Low R_DS(on)MOSFETs (80 mΩ at T_J= 25°C)

Operating Supply Voltage up to 50 V

(70 V Absolute Maximum)

The DRV8412/22/32 require two power supplies, one

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

for PVDD. The DRV8412/22/32 can operate at up to

500-kHz switching frequency while still maintain

precise control and high efficiency. They 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

DRV8412 (power pad down): up to 2 x 3 A

Continuous Output Current (2 x 6 A Peak) in

Dual Full Bridge Mode or 6 A Continuous

Current in Parallel Mode (12 A Peak)

•

DRV8422 (power pad up): up to 2 x 5 A

Continuous Output Current ( 2 x 9 A Peak) in

Dual Full Bridge Mode or 10 A Continuous

Current in Parallel Mode (18 A Peak)

DRV8432 (power pad up): up to 2 x 7 A

Continuous Output Current ( 2 x 12 A Peak) in

Dual Full Bridge Mode or 14 A Continuous

Current in Parallel Mode (24 A Peak)

protection.

The

DRV8412/22/32

have

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.

•

PWM Operating Frequency up to 500 kHz

Integrated Self-Protection Circuits Including

Undervoltage, Overtemperature, Overload, and

Short Circuit

The DRV8412/22/32 have unique independent supply

and ground pins for each half bridge, which makes it

possible to provide current measurement through

external shunt resistor and support multiple motors

with different power supply voltage requirements.
