Technical Data  
5.0 A H-Bridge with Load  
Current Feedback  
33887  
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 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.

20-PIN HSOP  
FK SUFFIX  
98ASA10583D  
36-PIN PQFN  
A Fault Status output pin 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).

The 33887 is parametrically specified over a temperature range of  
-40°C ≤ TA ≤ 125°C and a voltage range of 5.0 V ≤ V+ ≤ 28 V.  
Operation with voltages up to 40 V with derating of the specifications.
