LTC2917IMS-B1#PBF

LTC2917 is a low voltage single-supply monitor with selectable thresholds and an adjustable watchdog timer. 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 separate manual reset input on the device allows a simple push button interface. It is widely used in application such as handheld devices, cell phone base stations, automotive control systems, network servers, optical networking systems etc.
