SEMICONDUCTOR TECHNICAL DATA  
33887  
5.0 A H-Bridge with Load Current  
Feedback  
The 33887 is a monolithic H-Bridge Power IC with a load current feedback  
feature making it ideal for closed-loop DC motor control. The IC incorporates  
internal control logic, charge pump, gate drive, and low RDS(ON) MOSFET  
5.0 A H-BRIDGE WITH LOAD  
CURRENT FEEDBACK  
output circuitry. The 33887 is able to control inductive loads with continuous  
DC load currents up to 5.0 A, and with peak current active limiting between  
5.2 A and 7.8 A. Output loads can be pulse width modulated (PWM-ed) at  
frequencies up to 10 kHz. The load current feedback feature provides a  
proportional (1/375th of the load current) constant-current output suitable for  
monitoring by a microcontroller’s A/D input. This feature facilitates the design  
of closed-loop torque/speed control as well as open load detection.

VW (Pb-FREE) SUFFIX  
CASE 979-04  
A Fault Status output terminal reports undervoltage, short circuit, and  
overtemperature conditions. Two independent inputs provide polarity control  
of two half-bridge totem-pole outputs. Two disable inputs force the H-Bridge  
outputs to tri-state (exhibit high impedance).  
20-TERMINAL HSOP  
PNB (Pb-FREE) SUFFIX  
CASE 1503-01  
The 33887 is parametrically specified over a temperature range of  
36-TERMINAL PQFN  
-40°C ≤ TA ≤ 125°C and a voltage range of 5.0 V ≤ V+ ≤ 28 V. The IC can also  
be operated up to 40 V with derating of the specifications.
