Function
AAT3510/13/15: RESET output goes low whenever V
DD
falls below the reset threshold. CMOS push-pull output.
AAT3511/14/16: RESET output goes low whenever V
DD
falls below the reset threshold. Bidirectional CMOS push-
pull output intended to interface directly to microprocessors
with bi-directional resets.
AAT3517/18/19: RESET output goes low whenever V
DD
falls below the reset threshold. Open drain output. Connect
a pull-up resistor to any supply voltage up to 5.5V.
Ground connection pin.
RESET active-high output. This CMOS push-pull signal is
the logical inverse of RESET.
Manual reset input pin. Active low. Pull low to force a reset.
Watchdog input pin. Triggers a reset if it remains in a
steady state for the duration of the watchdog timer period.
Input voltage pin.
