NOTES
1. NC = NO CONNECT. DO NOT CONNECT TO THIS PIN.
2. 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.

No Connect. Do not connect to this pin.
1 to 5
2 to 6
VX1 to VX5 High Impedance Inputs to Supply Fault Detectors. Fault thresholds can be set from 0.573 V to
(VXx)
1.375 V. Alternatively, these pins can be used as general-purpose digital inputs.
6 to 9
7 to 10
VP1 to VP4
(VPx)
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.
10
11
VH
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.
11
14
AGND1
Ground Return for Input Attenuators.
12
15
REFGND Ground Return for On-Chip Reference Circuits.
13
16
REFIN
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.
14
17
REFOUT1 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.
21 to 30 26 to 35 PDO10 to
PDO1
Programmable Output Drivers.
31
38
PDOGND1 Ground Return for Output Drivers.
32
39
VCCP
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.
33
40
A0
Logic Input. This pin sets the seventh bit of the SMBus interface address.
34
41
A1
Logic Input. This pin sets the sixth bit of the SMBus interface address.
35
42
SCL
SMBus Clock Pin. Bidirectional open drain requires external resistive pull-up.
36
43
SDA
SMBus Data Pin. Bidirectional open drain requires external resistive pull-up.
37
44
AUX2
Auxiliary, Single-Ended ADC Input.
