Формирователи импульса сброса MAX835EUK+T

Схема контроля микропроцессора , 2.5В-11В питание, выход сброса с активным низким, с открытым стоком

The MAX835EUK+T is a micropower, latching voltage monitor in 5 pin SOT-23 package. This voltage monitors contain a 1.204V precision bandgap reference and a comparator with an output latch. It has push-pull output and can both source and sink current. Two external resistors set the trip-threshold voltage. It features a level-sensitive latch, eliminating the need to add hysteresis to prevent oscillations in battery-load-disconnect applications. Device is applicable in load switching and threshold detectors.

• Supply voltage range is 2.5V to 11V
