3 Description
The DRV8804 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 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
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 and a 16-pin HTSSOP
package (Eco-friendly: RoHS & no Sb/Br).
