The LTC2901-1IGN#PBF is a quad programmable Supply Monitor with adjustable reset and watchdog timer. It is suitable for systems with up to four supply voltages. One of 16 preset or adjustable voltage monitor combinations can be selected using an external resistor divider connected to the program pin. The preset voltage thresholds are accurate to ±1.5% over-temperature. All four voltage comparator outputs are connected to separate pins for individual supply monitoring. The reset and watchdog delay times are adjustable using external capacitors. Tight voltage threshold accuracy and glitch immunity ensure reliable reset operation without false triggering. The RST\ output is guaranteed to be in the correct state for VCC down to 1V. It features an open-drain RST\ output. The 43μA supply current makes the LTC2901 ideal for power conscious systems and it may be configured to monitor less than four inputs.
