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.

VCC

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