8 CHANNEL SERIAL INTERFACE LOW-SIDE DRIVER

DESCRIPTION

The U8C3060 provides an 8-channel low side driver with

overcurrent protection and open/shorted load detection. It has

built-in diodes to clamp turn-off transients generated by inductive

loads, and can be used to drive unipolar stepper motors, DC

motors, relays, solenoids, or other loads.

U8C3060 can supply up to 200 mA × 8 channel continuous

output current. The current driving capability increased with lower

PWM duty cycle. A single channel can deliver up to 560 mA

continuous output current.

A serial interface is provided to control the U8C3060 output

drivers, configure internal setting register and read the fault status

of each channel. Multiple U8C3060 devices can be daisy-chained

together to use a single serial interface. Energizing-time and

holding-PWM-Duty cycles are configurable through serial interface

as well. These functions allow for cooler running than traditional

always-on solutions.

Internal shutdown functions are provided for overcurrent

protection, short-circuit protection, under voltage lockout, and

overtemperature.U8C3060 can diagnosis an open load condition.

Fault information for each channel can be read out through serial

interface and indicated by an external fault pin.
