Functional Description
This input pin is connected to the master microcontroller providing the
required bit shift clock for SPI communication. This pin has a passive
internal pull-down resistance.
This data input is sampled on the positive edge of the SCLK. This pin has
a passive internal pull-down resistance.
SPI Logic power supply.
SPI data sent to the MCU by this pin. This data output changes on the
negative edge of SCLK, and when
This pin controls an external SMART MOSFET by logic level. This output
called OUT6.
If OUT6 is not used in the application, this output pin is set to logic high
when the current sense output becomes valid when CSNS sync SPI bit is
set to logic [1].
This pin is the ground for the logic and analog circuitry of the device.
Power supply pin.
This pin is the connection for an external tank capacitor (for internal use
only).
Protected 35 m high side power output to the load.
This pin is used to output a current proportional to OUT1:OUT5, FET in
current, and it is used externally to generate a ground-referenced voltage
for the microcontroller to monitor output current. Moreover, this pin can
report a voltage proportional to the temperature on the GND flag.
OUT1:OUT5, FET in current sensing and Temperature feedback choice is
SPI programmable.
