DESCRIPTION
The MP6604A is a dual H-bridge motor driver
IC that can drive stepper motors, brushed DC
motors, and other loads.
The device operates across a 4.5V to 45V input
voltage (VIN) range, and can deliver up to 2.5A
of output current (IOUT) per phase.
Internal safety and diagnostic features include
over-current protection (OCP), input overvoltage
protection (OVP), and input undervoltage
lockout (UVLO) protection, and thermal
shutdown.
The MP6604A has separate IN and EN pins
for each output pin.
The MP6604A is available in QFN-28
(4mmx5mm) and TSSOP-28EP packages.
