+3.3V pin. Can be powered by +3.3V Standby power if monitoring in
low power states is required. This pin also serves as the analog input
to monitor the 3.3V supply. This pin should be bypassed with a 0.1µf
capacitor in parallel with 100pf. A bulk capacitance of approximately
10µf needs to be in the near vicinity of the LM96000.
Ground for all analog and digital circuitry.
Analog input for +5V monitoring.
Analog input for +12V monitoring.
Analog input for +2.5V monitoring.
Analog input for VCCP (processor voltage) monitoring.
