Reservoir Capacitor for Central Charge Pump.
circuits of the ADM1060 and provides the first stage in the tripler circuits used to produce
12V of gate drive on PDO's 1- 4.
High Voltage Supply Input. 2 input ranges. A supply of between 2V and 6V or between
4.8V and 14.4V can be applied to this pin. The V
the ADM1060 if it is the highest supply supervised.
Positive Only Supply Inputs. 2 input ranges. A supply of between 1V and 3V or between
2V and 6V can be applied to this pin. The V
power the ADM1060 if it is the highest supply supervised.
Bipolar Supply Inputs. 2 modes. 2 input ranges in positive mode. 1 input range in negative
mode. A supply of between -6V and -2V can be applied to this pin when set in negative mode.
A supply of between 1V and 3V or between 2V and 6V can be applied to this pin when set in
positive mode.
Programmable Driver Output pin.
pull-up options to VDD or VPn. PDO's 1 to 4 can also provide a charge-pump generated
gate drive for external N- Channel FET
Watchdog Input. Used to monitor a processor clock and asserts a fault condition if the clock
fails to transition from low-to-high or high-to-low within a programmed timeout period (up to
18sec).
General Purpose Logic Input. TTL compatible Logic.
