Master-Out Slave- This data input is sampled on the positive edge of the SCLK. This pin has a
In
passive internal pull-down resistance.
Logic Supply SPI Logic power supply.
Master-In Slave- SPI data is sent to the MCU by this pin. This data output changes on the
Out
negative edge of SCLK and when CS is high, this pin is high-impedance.
External FET Gate
This pin controls an external SMART MOSFET by logic level. This output is also
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].
Ground
This pin is the ground for the logic and analog circuitry of the device.(1)

Current Sense This pin is used to output a current proportional to OUT1:OUT5, FETin current,
Output
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, FETin current sensing and Temperature feedback choice is SPI
programmable.
Notes
1. The pins 14, 17 and 23 must be shorted on the board.
