Maxim Integrated (MAX809SEUR+T) Supervisory Circuit, 1.2V-5.5Vin

Supervisory Circuit, Active-Low Reset, 1.2V-5.5Vin, SOT-23-3 Product Overview The MAX809SEUR+T is a three pin microprocessor supervisory circuit in SOT-23 package. This device is used to monitor power supplies in microprocessor and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, +3V or +2.5V powered circuits. The MAX809S performs a single function. It asserts reset signal whenever VCC supply voltage declines below preset threshold keeping it asserted for 140ms after VCC has risen above reset threshold. Reset threshold voltage of 2.93V Fully specified over temperature Active low push pull RESET\ output Reset active timeout period of 240ms 12µA supply current Guaranteed reset valid to VCC = +1V Power supply transient immunity Operating temperature range from -40°C to 105°C Supply voltage range from 1.2V to 5.5V Automotive; Computers: Desktop, Workstation, Server; Controllers; Critical µP and µC Power Monitoring; Intelligent Instruments; Portable Battery-Powered Equipment Applications Automotive, System Monitoring, Portable Devices Product Information Threshold Voltage: 2.93V No. of Supervisors / Monitors: 1Monitors Supply Voltage Min: 1.2V Supply Voltage Max: 5.5V Reset Type: Active-Low Digital IC Case: SOT-23 No. of Pins: 3Pins Delay Time: 240ms Operating Temperature Min: -40°C Operating Temperature Max: 105°C MSL: MSL 1 - Unlimited
