Description

General part information

LTC2934 Series

The LTC2934 ultra-low power voltage monitor provides system initialization, power-fail warning and reset generation functions. Low quiescent current (500nA typical) makes the LTC2934 an ideal choice for battery-operated applications.Precision power-fail and reset voltages can be conﬁgured independently. Early warning of an impending low voltage condition is provided at the power-fail output (PFO) when the PFI input falls below 0.4V. Supervisory circuits monitor the ADJ input and pullRSTlow when ADJ falls below 0.4V. When ADJ is rising from an under-threshold condition, an internal reset timer is started after exceeding the ADJ threshold by 5%. The reset timeout delays the return of theRSToutput to a high state. A pushbutton switch connected to theMRinput is typically used to force a manual reset. OutputsRSTandPFOare available with open-drain (LTC2934-1) or active pull-up circuits (LTC2934-2). Operating temperature range is from –40ºC to 85ºC.ApplicationsPortable EquipmentBattery-Powered EquipmentSecurity SystemsPoint-of-Sale DevicesWireless Systems
