The LTC2918IMS-B1#PBF is a low-voltage single-supply Voltage Supervisor with manual reset input, 27 selectable thresholds and an adjustable watchdog timer. The parts operate from 1.5 to 5.5V and consume a quiescent current of only 30μA. Two three state inputs select one of nine internally programmed thresholds without the need for external resistors. The tolerance for the LTC2918 is fixed at -5%. Threshold accuracy is guaranteed at ±1.5% over the entire operating temperature range. Glitch filtering ensures reliable reset operation without false triggering. The reset timeout and the watchdog timeout may be set with no external components or adjusted using an external capacitor. A windowed watchdog feature is available for high-reliability applications (B1 versions). A separate manual reset input on the LTC2918-B allows a simple push button interface.
