SLES242C –DECEMBER 2009–REVISED MAY 2010  
Dual Full Bridge PWM Motor Driver  
Check for Samples: DRV8412, DRV8432  
The DRV8412/32 require two power supplies, one at  
1
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 RDS(on) MOSFETs (80 mΩ at TJ = 25°C)  
Operating Supply Voltage up to 50 V  
(70 V Absolute Maximum)  
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  
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  
GVDD_C  
The DRV8412/32 are high performance, integrated  
dual full bridge motor drivers with an advanced  
protection system.  
GVDD_D  
Because of the low RDS(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.
