DESCRIPTION
The DRV8804 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 DRV8804 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).
A serial interface is provided including a serial data output, which can be daisy-chained to control multiple
devices with one serial 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 DRV8804 is available in a 20-pin thermally-enhanced SOIC package and a 16-pin HTSSOP package
(Eco-friendly: RoHS & no Sb/Br).
