LTC1326 - Micropower Precision Triple Supply Monitor

The LTC™1326/LTC1326-2.5 are triple supply monitors intended for systems with multiple supply voltages. They provide micropower operation, small size and high accuracy supply monitoring. Tight 0.75% threshold accuracy and glitch immunity ensure reliable reset operation without false triggering. The 20µA typical supply current makes the LTC1326/LTC1326-2.5 ideal for power-conscious systems. The RST output is guaranteed to be in the correct state for VCC3, VCC5 or VCC25 down to 1V. The LTC1326/LTC1326-2.5 can be configured to monitor one, two or three inputs, depending on system requirements. A manual push-button reset input provides the ability to generate a very narrow �soft� reset pulse (100µs typ) or a 200ms reset pulse equivalent to a power-on reset. Both SRST and RST outputs are open-drain and can be OR-tied with other reset sources.
