The Current Sense pin sources a current proportional to the designated
HS0
The IN0 : IN3 high-side input pins are used to directly control HS0 : HS3 high-
side output pins, respectively.
This pin reports an analog value proportional to the temperature of the GND
flag (pins 14, 17, 23). It is used by the MCU to monitor board temperature.
This pin is an open drain configured output requiring an external pullup resistor
to V
This input pin controls the device mode and watchdog timeout feature if
enabled.
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 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 pin 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
