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 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 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).
