DESCRIPTION

The MP6606 is an 8-channel low-side driver IC

with a serial interface. The device integrates

low-side MOSFET (LS-FET) switches and highside

clamp diodes to drive inductive loads,

which makes it well-suited for unipolar stepper

motor and solenoid drives.

The MP6606 operates from a supply voltage of

up to 60V, and can deliver an output current

(IOUT) up to 750mA (depending on PCB design

and thermal conditions). The maximum voltage

on the motor drive output pins is 60V.

Internal safety features include over-current

protection (OCP), under-voltage lockout

(UVLO), and thermal shutdown.

The MP6606 is available in a TSSOP-20EP

package with an exposed pad.
