Description
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 V, from 1.25 V to 3 V, and from 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 V to 14.4 V and from 2.5 V to 6 V.
Ground Return for Input Attenuators.
Ground Return for On-Chip Reference Circuits.
No Connect.
Reference Output, 2.048 V. Note that a capacitor must always be connected between this pin and REFGND.
A 10 μF capacitor is recommended for this purpose.
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. A 10 μF capacitor is recommended for this purpose.
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. Bidirectional open drain requires external resistive pull-up.
SMBus Data Pin. Bidirectional open drain requires external resistive pull-up.
Device Supply Voltage. Linearly regulated from the highest of the VPx and VH pins to a typical of 4.75 V.
A capacitor must be connected between this pin and GND. A 10 μF capacitor is recommended for
this purpose.
Supply Ground.
