Technical Data
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 R DS(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.
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 ≤ T A ≤ 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.
