LTC2918IMS-B1#PBF

LTC2918 is a low voltage single-supply monitor with selectable thresholds and an adjustable watchdog timer. Two three state inputs select one of nine internally programmed thresholds without the need for external resistors. The tolerance for the device 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. It is widely used in application such as handheld devices, cell phone base stations, automotive control systems, network servers, optical networking systems etc.
