MAX809SEUR+T Datasheet PDF - Maxim Integrated

●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
