3 Description
The DRV8809/DRV8810 provides an integrated
motor driver solution. The chip has four H-bridges
internally and is configurable to eight different modes
of combination motor driver control.
The output driver block for each H-bridge consists of
N-channel power MOSFETs configured as full H-
bridges to drive the motor windings. The stepper
motor control has a 16-step mode programmable
through the 3-wire serial interface (SPI). The SPI
input pins are 3.3-V compatible and 5-V tolerant.
The DRV8809/DRV8810 has three DC-DC switch-
mode buck converters to generate a programmable
output voltage from 1.5 V to 80% of VDIN (channel A)
or up to 10 V (for channel B and channel C), with up
to 1.5-A load current capability. The outputs are
selected using the C_SELECT terminal at start-up or
using serial interface during operation.
An internal shutdown function is provided for
overcurrent protection (OCP), short-circuit protection,
overvoltage/undervoltage lockout (UVLO), and
thermal shutdown (TSD). Also, the device has a reset
function that operates at power on and at input to the
In-Reset pin.
