DESCRIPTION
The DRV8803 provides a 4-channel low side driver with overcurrent protection. 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.
The DRV8803 can supply up to 1.5-A (single channel on) or 800-mA (four channels on) continuous output
current (with adequate PCB heatsinking at 25
°C).
The device is controlled via a simple parallel interface.
Internal shutdown functions are provided for over current protection, short circuit protection, under voltage
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).
