NOTES
1. THE LFCSP HAS AN EXPOSED PAD ON THE BOTTOM. THIS
PAD IS A NO CONNECT (NC). IF POSSIBLE, THIS PAD
SHOULD BE SOLDERED TO THE BOARD FOR IMPROVED
MECHANICAL STABILITY.
2. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN.

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, from 1.25 V to 3.00 V,
and from 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 from 2.5 V to 6.0 V.

Ground Return for Input Attenuators.
2 Ground Return for On-Chip Reference Circuits.
Reference Input for ADC. Nominally, 2.048 V. This pin must be driven by a reference voltage.
The on-board reference can be used by connecting the REFOUT pin to the REFIN pin.
Reference Output, 2.048 V. Typically connected to REFIN. Note that the capacitor must be
connected between this pin and REFGND. A 10 μF capacitor is recommended for this purpose.
SMBus Clock Pin. Bidirectional open drain requires external resistive pull-up.
SMBus Data Pin. Bidirectional open drain requires external resistive pull-up.
Programmable Output Drivers.
2
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.
