Sets V
SPI control data output pin from the IC to the MCU.
SPI control data input pin from the MCU to the IC.
The SCLK input is the clock signal input for synchronization of serial data transfer.
This pin is an input connected to a chip select output of an MCU.
This pin connects an external capacitor, which is the storage reservoir for the
internal charge pump.
This input pin is a connection to a capacitor that determines the default time the
output will be turned off when the low-side current comparator is tripped, if PWM
has not commanded it. The typical value with a 0.1 µF is 100 µs. If shorted, the
feature is disabled.
This input pin is the primary H-Bridge power input. Note: Not reverse voltage
protected.
These output pins drive the bi-directional motor and must be connected together
on the PC board.
These pins must be connected on the PC board to the exposed pad.
These pins have no internal connections.
This output pin pulses high anytime the low-side current comparator is tripped.
These input pins determine the mode of the IC; namely, sleep, standby, and run.
These output pins drive the bi-directional motor and must be connected together
on the PC board.
