Mute Operating Conditions
Pin Out
Operation Of Supervisor Circuit.
The reset input of a µP initializes the device into a known
state. The PA4101 supervisor circuitry asserts a forced reset
output to prevent code execution errors during Power-up,
power-down and brownout conditions.
RESET is valid for V
threshold, an internal timer maintains the output for the reset
period timeout. After this interval, reset goes high.
Any time V
activates. When V
internal timer starts. Reset holds until V
threshold for longer than the reset timeout period. After this
time the reset release
