3 Description

The DRV8803 provides a 4-channel low side driver

with overcurrent protection. The device has builtin

diodes to clamp turnoff transients generated by

inductive loads and can be used to drive unipolar

stepper motors, DC motors, relays, solenoids, or other

loads.

In the SOIC (DW) package, the DRV8803 can supply

up to 1.5A (one channel on) or 800mA (all channels

on) continuous output current per channel, at 25°C. In

the HTSSOP (PWP) package, the device can supply

up to 2A (one channel on) or 1A (four channels on)

continuous output current per channel, at 25°C . In

the SOT-23-THN (DYZ) package, the DRV8803 can

supply up to 1.9A (one channel on) or 900mA (all

channels on) continuous output current per channel,

at 25°C with proper PCB heatsinking.

The device is controlled through a simple parallel

interface.

Internal shutdown functions are provided for

over current protection, short circuit protection,

undervoltage lockout and overtemperature and faults

are indicated by a fault output pin.

The DRV8803 is available in a 20-pin thermallyenhanced

SOIC package, 16-pin HTSSOP package

and 16-pin SOT-23-THN package (Eco-friendly: RoHS

& no Sb/Br).
