This pin is used to output a current proportional to the designated
HS0-1 output.
This pin is used to input a Logic [1] signal so as to enable the
watchdog timer function.
This input pin is used to initialize the device configuration and fault
registers, as well as place the device in a low current Sleep mode.
This input pin is used to directly control the output HS0.
This is an open drain configured output requiring an external pull-up
resistor to VDD for fault reporting.
The value of the resistance connected between this pin and ground
determines the state of the outputs after a watchdog timeout occurs.
This input pin is connected to a chip select output of a master
microcontroller (MCU).
This input pin is connected to the MCU providing the required bit shift
clock for SPI communication.
This is a command data input pin connected to the SPI Serial Data
Output of the MCU or to the SO pin of the previous device of a daisy
chain of devices.
This is an external voltage input pin used to supply power to the SPI
circuit.
