DESCRIPTION

The MP6605C is a 4-channel, low-side driver IC

with an I2C interface. The device integrates low-

side MOSFET (LS-FET) switches and high-side

clamp diodes to drive inductive loads. It is

typically used for unipolar stepper motors and

solenoid drivers.

The MP6605C operates from a supply voltage of

up to 60V, and can deliver an output current

(IOUT) up to 1.5A, depending on the PCB design

and thermal conditions. The maximum voltage

on the motor drive

r’s output pins is 60V.

Internal safety features include over-current

protection

(OCP),

under-voltage

lockout

(UVLO), and over-temperature protection (OTP).

The

MP6605C

is

available in

a QFN-24

(4mmx4mm) package.
