RT9807 - Micro-Power Voltage Detector

Description

The RT9807 is a micro-power voltage detector with deglitched manual reset input which supervises the power supply voltage level for microprocessors (μP) or digital systems.

Features

  • low supply current of 3μA. The RT9807 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. The timeout period of this reset signal can be adjusted via an external capacitor. Once VDD recovers above the threshold level, the reset signal will be released after a certain delay time. To manually pull reset signal low, just pull the manual reset input (MR) below the specified logic-low level. The RT9807 is available in an SOT-23-5.

RT9807 Micro-Power Voltage Detector with Manual Reset General Description The RT9807 is a micro-power voltage detector with deglitched manual reset input which supervises the power supply voltage level for microprocessors (μP) or digital systems. It provides internally fixed threshold levels ranging from 1.2V to 3.3V with 0.1V per step, which covers most digital applications. It features low supply current of 3μA. The RT9807 performs supervisory function by sending out a reset signal whenever the VDD voltage falls below a preset threshold level. The timeout period of this reset signal can be adjusted via an external capacitor. Once VDD recovers above the threshold level, the reset signal will be released after a certain delay time.
