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 Hbridges 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 switchmode 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 oper...
