Description
No connection.
High impedance inputs to supply fault detectors. Fault thresholds can be set at between
0.573V and 1.375V. 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 allow thresholds between 2.5V-6V, 1.25V-3V and 0.573V-
1.375V.
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; these allow thresholds between 6V-14.4V,2.5V-6V and 1.25V-3V.
No connection.
Ground return for input attenuators.
Ground return for on-chip reference circuits.
Reference input for ADC, nominally 2.048V.
2.048V reference output.
Voltage output DACs. Default to high impedance at power-up.
No connection.
Programmable output drivers.
No connection.
Ground return for output drivers
Central charge pump voltage of 5.25V. A reservoir capacitor must be connected between this
pin and GND.
Logic input which sets the 7th bit of the SMBus interface address.
Logic input which sets the 6th bit of the SMBus interface address.
SMBus clock pin. Open drain output requiring external resistive pull-up.
SMBus data i/o pin. Open drain output requiring external resistive pull-up.
External Thermal Diode Cathode Connection
External Thermal Diode Anode Connection
Device supply voltage. Linearly regulated from the highest of the VP1-4,VH pins and clamped
to a maximum of 4.75V
Supply ground.
No connection.
