Product Details

The LTC2912 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 LTC2912 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.

Three output configurations are available: the LTC2912‑1 has a latch control for the OV output; the LTC2912-2 has an OV and UV output disable feature for margining applications; the LTC2912-3 is identical to the LTC2912-1 but with a noninverting, OV output.

The LTC2912 provides a precise, versatile, space-conscious micropower solution for voltage monitoring.
