Functional Description
150 mA, LDO1 output pin.
LDO5 enable input.
LDO4 enable input.
LDO3 enable input.
Externally pulled high, open drain output to processor/memory reset.
Externally pulled high, open drain output to processor interrupt indicating KYBD has gone
high.
Input from the processor to the LP3927. A HIGH indicates a steady supply of power is
granted. Refer to ’Application Hints’ section for more detail.
An active high input signal indicating the keyboard “On/Off” button has been asserted. Refer
to ’Application Hints’ section for more detail.
Digital ground, used primarily for the digital and DAC circuits.
Active low input indicating a battery charger insertion Refer to ’Application Hints’ section for
more detail.
Reference bypass pin.
Pin used for production testing, factory use only. This pin should be grounded in applications.
