Dual Full Bridge PWM Motor Driver

Check for Samples: DRV8412, DRV8432

The DRV8412/32 require two power supplies, one at

FEATURES

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

PVDD. The DRV8412/32 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

protection. The DRV8412/32 have 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 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)

•

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)

•

PWM Operating Frequency up to 500 kHz

Integrated Self-Protection Circuits Including

Undervoltage, Overtemperature, Overload, and

Short Circuit

The DRV8412/32 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.

DESCRIPTION

GVDD_C

GVDD_D

The DRV8412/32 are high performance, integrated

dual full bridge motor drivers with an advanced

protection system.

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%, which enables

the use of smaller power supplies and heatsinks, and

are good candidates for energy efficient applications.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
