This pin is connected to the Source of the power MOSFET for the I/O supply and it provides the negative sensing for the internal current sensing circuitry. This pin selects a range of output voltages for the DAC. When in the LO state the range is 1.3V to 2.05V and when it switches to HI state the range is 2.0V to 3.5V. This pin is TTL compatible that realizes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a 27K V resistor to 5V supply. MSB input to the DAC that programs the output voltage. This pin is TTL compatible that realizes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a 27K V resistor to 5V supply. Input to the DAC that programs the output voltage. This pin is TTL compatible that real- izes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a 27K V resistor to 5V supply. Input to the DAC that programs the output voltage. This pin is TTL compatible that real- izes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a 27K V resistor to 5V supply. LSB input to the DAC that programs the output voltage. This pin is TTL compatible that realizes a logic “1” as either HI or Open. When left open, this pin is pulled up internally by a 27K V resistor to 5V supply. This pin is an open collector output that switches LO when any of the outputs are outside of the specified under voltage trip point. It also switches low when VSEN1 pin is more than 10% above the DAC voltage setting. This pin is connected to the Drain of the power MOSFET of the I/O supply and it provides the positive sensing for the internal current sensing circuitry. An external resistor pro- grams the CS threshold depending on the RDS of the power MOSFET. An external ca- pacitor is placed in parallel with the programming resistor to provide high frequency noise filtering.
