MAX16058ATA29+

产品概述

The MAX16058ATA29+ is a 125nA supervisory circuit with capacitor having adjustable reset and watchdog timeouts in 8 pin TDFN-EP package. It is an ultra-low-current 125nA microprocessor (µP) supervisory circuit that monitors a single system supply voltage. This device assert an active-low reset signal whenever the VCC supply voltage drops below the factory-trimmed reset threshold, manual reset is pulled low, or the watchdog timer runs out. The reset output remains asserted for an adjustable reset timeout period after VCC rises above the reset threshold. It features adjustable reset and watchdog timeout using external capacitors. It contains a watchdog timer with a watchdog select input (WDS) that multiplies the watchdog timeout period by 128. It is an open-drain output-type configuration. Typical applications include battery-powered equipment, PDAs/cell phones, MP3 players/pagers, glucose monitors/patient monitors and HVAC.
