SLES256 –MAY 2010  
Three Phase PWM Motor Driver  
Check for Samples: DRV8312, DRV8332  
Because of the low RDS(on) of the power 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.

FEATURES  
•
•
•
•
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)  
The DRV8312/32 require two power supplies, one at  
12 V for GVDD and VDD, and another up to 50 V for  
PVDD. The DRV8312/32 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 DRV8312/32 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.  
DRV8312 (power pad down): up to 3.5 A  
Continuous Phase Current (6.5 A Peak)  
DRV8332 (power pad up): up to 8 A  
Continuous Phase Current ( 13 A Peak)

Independent Control of Three Phases  
PWM Operating Frequency up to 500 kHz  
Integrated Self-Protection Circuits Including  
Undervoltage, Overtemperature, Overload, and  
Short Circuit

•
•
Programmable Cycle-by-Cycle Current Limit  
Protection  
Independent Supply and Ground Pins for Each  
Half Bridge  
Intelligent Gate Drive and Cross Conduction  
Prevention  
The DRV8312/32 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 half bridge drivers  
with different power supply voltage requirements.  
No External Snubber or Schottky Diode is  
Required
