Description
No Connection.
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. Two 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.
Reference Output, 2.048 V.
SMBus Clock Pin. Open-drain output requires external resistive pull-up.
SMBus Data I/O Pin. Open-drain output requires external resistive pull-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.
External Temperature Sensor 1 Cathode Connection.
External Temperature Sensor 1 Anode Connection.
