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.

In the SOIC (DW) package, the DRV8804 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.

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).
