High Impedance Inputs to Supply Fault Detectors. Fault thresholds can be set from 0.573 V to 1.375 V.
Alternatively, these pins can be used as general-purpose digital inputs.
Low Voltage Inputs to Supply Fault Detectors. Three input ranges can be set by altering the input
attenuation on a potential divider connected to these pins, the output of which connects to a supply
fault detector. These pins allow thresholds from 2.5 V to 6.0 V, 1.25 V to 3.00 V, and 0.573 V to 1.375 V.
High Voltage Input to Supply Fault Detectors. Three input ranges can be set by altering the input
attenuation on a potential divider connected to this pin, the output of which connects to a supply
fault detector. This pin allows thresholds from 6.0 V to 14.4 V and 2.5 V to 6.0 V.
Ground Return for Input Attenuators.
Ground Return for On-Chip Reference Circuits.
Reference Input for ADC. Nominally, 2.048 V.
2.048 V Reference Output.
Voltage Output DACs. These pins default to high impedance at power-up.
Programmable Output Drivers.
Ground Return for Output Drivers.
Central Charge-Pump Voltage of 5.25 V. A reservoir capacitor must be connected between this pin
and GND.
Logic Input. This pin sets the seventh bit of the SMBus interface address.
Logic Input. This pin sets the sixth bit of the SMBus interface address.
SMBus Clock Pin. Open-drain output requires external resistive pull-up.
SMBus Data I/O Pin. Open-drain output requires external resistive pull-up.
Auxiliary, Single-Ended ADC Input.
Auxiliary, Single-Ended ADC Input.
Device Supply Voltage. Linearly regulated from the highest of the VP1–4, VH pins to a typical of 4.75 V.
Supply Ground.
