Function

Positive charge pump feedback input. Regulates to 1.2V

nominal. Connect feedback resistive divider to analog

ground (GND).

Enable input. When EN is pulled low, the device shuts off

and draws only 1.0µA. When high, it is in normal opera-

tion. Drive EN through an external resistor.

Internal reference bypass terminal. Connect a 0.1µF capac-

itor from this terminal to analog ground (GND). External

load capability to 50µA. REF is disabled in shutdown.

Negative charge pump regulator feedback input. Regulates

to 0V nominal. Connect feedback resistive divider to the

reference (REF).

Positive charge pump driver output. Output high level is VIN

and low level is PGND.

Ground.

Negative charge pump driver output. Output high level is

VIN and low level is PGND.

Input voltage: 2.7V to 5.5V.
