MAX809SEUR+T

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
