SINGLE-CELL TO 3-V/3.3-V, 20-mA DUAL OUTPUT,
HIGH-EFFICIENCY CHARGE PUMP WITH SNOOZE MODE
SLVS362A – MAY 2001 – REVISED AUGUST 2001
description (continued)
Output 1 (OUT1) can deliver a maximum of 40 mA, from a 1-V input, with output 2 (OUT2) not loaded. OUT2
can deliver a maximum of 20 mA, from a 1-V input, with OUT1 not loaded. Both outputs can be loaded at the
same time, but the total output current of the first voltage doubler must not exceed 40 mA. For example, the load
at OUT1 is 20 mA and the load at output 2 is 10 mA.
In snooze mode, the devices operate with a typical operating current of 2 µA, while the output voltage is
maintained at 3.3 V ±10% or 3 V ±10%, respectively. This is lower than the self-discharge current of most
batteries. Load current in snooze mode is limited to 2 mA. If the load current increases above 2 mA, the output
voltage drops further and the devices automatically exits the snooze mode and operate in normal mode to
regulate to the nominal output voltage with higher output currents. The device is set into the snooze mode by
taking the SNOOZE pin low, and is set into normal operating mode by taking the SNOOZE pin high.
A power-good function supervises the output voltage of OUT2 and can be used for power up and power down
sequencing. Power-good (PG) is offered as either open-drain or push-pull output.
