Addresses 1 through 5. This is the I2C address select input. Select the appropriate binary address on these pins
by connecting this pin to device ground for a logic low and tying this pin to the VL pin for a logic high.

This pin is normally to be held low. It has been reserved for future expansion of the TPS238x device family

This is an open drain output that goes low if a fault condition is produced on any of the eight ports.
This pin can be used to override the internal POR. When held low, the I2C interface, all the state machines, and
registers are held in reset. When all internal and external supplies are within specification, and this pin is set to
a logic high level, the POR delay begins. The I2C interface and registers becomes active within eight CLK
periods of this event and communications to read or preset registers can begin. The reset delay for the
remainder of the device then extinguishes within 65536 CLK periods.
Serial clock input pin for the I2C interface.
Serial data input pin for the I2C interface. When jumpered with the SDA_O pin, this connection becomes the
standard bi-directional serial data line (SDA).
Serial data open drain output for the I2C interface. When jumpered with the SDA_I pin, this connection
becomes the standard bi-directional serial data line (SDA). This is a high-voltage open drain output that can
drive opto-coupler LEDs directly from the +48-V bus with an external, series current limiting resistor.
