ADI LTC2912HDDB-1#TRMPBF

简单复位/加电复位可调节/可选择1

Overview

The LTC2912HDDB-1 voltage monitor is designed to detect power supply undervoltage and overvoltage events. The VL and VH monitor inputs include filtering to reject brief glitches, thereby ensuring reliable reset operation without false or noisy triggering. An adjustable timer defines the duration of the overvoltage and undervoltage reset outputs which function independently. While the LTC2912HDDB-1 operates directly from 2.3V to 6V supplies, an internal VCC shunt regulator coupled with low supply current demand allows operation from higher voltages such as 12V, 24V or 48V.

The LTC2912HDDB-1 provides a precise, versatile, space-conscious micropower solution for voltage monitoring.
