LTC2956IUD-1#PBF

Power Supply Controllers, Monitors Overview

The LTC2956IUD-1#PBF is a supervisory circuit manufactured by Analog Devices Inc., designed for voltage monitoring and system reset control. It operates within a supply voltage range up to 36 V and features a threshold voltage of 900 mV. The device provides active high, active low, and open drain outputs with a fixed reset delay time of 250 ms. It consumes a typical operating supply current of 800 nA, supporting low-power applications. The component is housed in a QFN-12 package suitable for surface mount installation and functions reliably across an extended temperature range from -40°C to +85°C.
