These outputs are current and thermal overload protected. Maximum
steady state current through each of these outputs is 800 mA.
This is an external input pin used to supply power to the SPI circuit.
This is an output pin connected to the SPI Serial Data Input pin of the
MCU or to the SI pin of the next device in a daisy chain.
This is an input pin connected to a chip select output of a microcontroller
(MCU).
This input pin is connected to the SCLK pin of the master MCU, which is
a bit (shift) clock for the SPI port.
This input pin is connected to the SPI Serial Data Output pin of the MCU
from which it receives output command data.
This input pin is used to directly control a number of the low-side devices
as configured by SPI.
Each high-side input pin is used to directly control only one designated
high-side output.
These pins deliver a metered amount of the high-side output current that
can be used to generate signal ground referenced output voltages for use
by the MCU.
Each pin is the source of a 40 mΩ MOSFET high-side driver, which
delivers current through the connected loads.
These pins are not connected internally.
Each pin is the source of a 10 mΩ MOSFET high-side driver, which
delivers current through the connected loads.
This pin is used to input a logic [1] signal in order 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 standby mode.
