Open-Drain, Active-Low Reset Output. RESET asserts when any input voltage falls below the selected
threshold, the watchdog timer expires, or when MR is pulled low. RESET remains asserted for default
(200ms) or adjustable reset timeout period after all assertion-causing conditions are cleared. An
external pullup resister is required.
Reset Timeout Adjust Input. Connect an external capacitor between SRT and GND to set the reset
timeout period. The timeout period is calculated by t
