LTC2935ITS8-2#TRMPBF

LTC2935-2 is an ultra-low power voltage monitor provides system initialization, power-fail warning and reset generation functions. Low quiescent current (500nA typical) makes the device an ideal choice for battery-operated applications. Three binary threshold-select inputs configure one of eight integrated reset thresholds, ranging from 1.6V to 3.45V in pre-determined increments. Early warning of an impending low voltage condition is provided at the power fail output (PFO), whose threshold is above the configured reset threshold. Supervisory circuits monitor VCC and pull RST low when VCC drops below the configured reset threshold. When VCC is rising from an under-threshold condition, an internal reset timer is started after exceeding the reset threshold by 5%. It is widely used in application such as portable equipment, battery-powered equipment, security systems, point-of-sale devices, wireless systems etc.
