RESET

Active-High Reset Output (AS1908). This pin stays high whenever VCC is

below the RESET threshold VTH (see page 7), and for tTP (see page 4) after VCC

rises above VTH.

RESETN

Active-Low Reset Output (AS1907, AS1909). This pin remains low while VCC

is below the RESET threshold VTH (see page 7), and for tTP (see page 4) after

VCC rises above VTH.

Note: This pin is open-drain on the AS1909.

3VCC

Positive Supply Voltage. Connect to +0.7 to +3.6V supply.
