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).
