Master-Out Slave- This data input is sampled on the positive edge of the SCLK. This terminal has

In

an active internal pulldown current source.

Logic Supply SPI Logic power supply.

Master-In Slave- SPI data is sent to the MCU by this terminal. This data output changes on the

Out

negative edge of SCLK and when CS is high, this terminal is high impedance.

External FET Gate This terminal controls an external SMART MOSFET by logic level. This output

is also called OUT6.

Ground

This terminal is the ground for the logic and analog circuitry of the device(1).

Current Sense This terminal is used to output a current proportional to OUT1:OUT5, FETin

Output

current, and it is used externally to generate a ground-referenced voltage for the

microcontroller to monitor output current. OUT1:OUT5 and FETin choice is SPI

programmable.

Notes

1. The pins 14, 17 and 23 must be shorted on the board.
