LTC2917IMS-A1#PBF (LINEAR TECHNOLOGY)

The LTC2917IMS-A1#PBF is a low-voltage single-supply Voltage Supervisor with 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. For the LTC2917, an additional three state input determines the tolerance (-5%, -10%, -15%). 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).
