MC33887 : Integrated H-bridge with sleep mode
The MC33887 is a monolithic power IC comprising control logic,
charge pump, gate drive, and low RDS(ON) MOSFET output H-Bridge
circuitry into a small surface mount package. It is designed to
drive inductive loads with RMS currents up to 5.2 A in both
directions. In addition, the current drive can be pulse width
modulated (PWM) at frequencies up to 20 kHz. An internal current
mirror circuit provides a proportional (1/400 th ) sample of the
output current, which may be used to provide feedback or load
information to a microcontroller µs A/D input. Under voltage, over
temperature, and over current conditions are detected and reported
via a status flag output. Output control is via two independent
inputs (each half of the bridge may be utilized as an independent
totem pole output). Enables can place the bridge into sleep mode
(<25 µA). Typical applications include: DC-motor acme lead screw
actuators, servo gear actuators, bi-directional thrust solenoids,
and fractional horsepower DC-motor control.
