DESCRIPTION
The CRM2139 is a dual bridge motor driver which has
two H-bridge drivers, and can drive two DC brush
motors, a bipolar stepper motor, solenoids, or other
inductive loads.
It operates from 2.7V to 15V, and can deliver load
current up to 700mA per channel. The output driver
block of each H-bridge consists of N-channel power
MOSFETS configured as an H-bridge to drive the motor
windings. Each H-bridge includes circuitry to regulate or
limit the winding current.
The internal safety features include sinking and
sourcing current limits implemented with external
sensors, under-voltage lockout, over current protection
(OCP) and thermal shutdown. An over-temperature
output flag is available to indicate thermal shutdown.
The CRM2139 is packaged in 16-pin, 5.0mm×6.4mm
TSSOP-EP and TSSOP, 3mm×3mm and 4mmx4mm
QFN package with an exposed thermal pad on the back.
