Analog Supply Voltage.
Analog power supply for internal analog circuitry.
Positive TIP Current Control.
Analog current output driving Q1.
Negative TIP Current Control.
Analog current output driving Q4.
Digital Supply Voltage.
Digital power supply for internal digital circuitry.

tied to ground for normal operation.
DC Feed-Forward/High Current General Purpose Output.
Feed-forward drive of external bipolar transistors to improve dc-dc converter
efficiency.
DC Drive/Battery Switch.
DC-DC converter control signal output which drives external bipolar transistor.
Battery switch control signal output which drives external bipolar transistor.
Cascaded SDI output signal for daisy-chain mode.
Serial Port Data Out.
Serial port control data output.
Serial Port Data In.
Serial port control data input.
Serial Port Bit Clock Input.
Serial port clock input. Controls the serial data on SDO and latches the data on
SDI.
