3 Description
The DRV8803 provides a 4-channel low side driver
with overcurrent protection. It has built-in 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 1.5-A (one channel on) or 800-mA (all channels
on) continuous output current per channel, at 25°C. In
the HTSSOP (PWP) package, it can supply up to 2-A
(one channel on) or 1-A (four 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 thermally-
enhanced SOIC package and a 16-pin HTSSOP
package (Eco-friendly: RoHS & no Sb/Br).
