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

over-

voltage protection (OVP), and input under-

voltage 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.
