3 Description

The DRV8804 provides a 4-channel low-side driver with overcurrent protection. The device 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 DRV8804 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 DRV8804 can supply up to 1.9A (one channel on) or 900mA (all channels on) continuous output current per chanel, 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 overcurrent protection, short-circuit protection, undervoltage lockout, and overtemperature, and faults are indicated by a fault output pin.

The DRV8804 is available in a 20-pin, thermally-enhanced SOIC package , 16-pin HTSSOP package and 16-pin SOT-23-THN package (Eco-friendly: RoHS & no Sb/Br).
