LTC2938CDE#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2938CDE#TRPBF is a configurable multi-supply voltage monitor manufactured by Analog Devices Inc. It features four independent input channels with programmable thresholds, housed in an 8-lead DFN package. The device provides push-pull outputs and includes a watchdog timer for system reliability. Operating from a supply voltage range of 1 V to 7 V, it draws a typical quiescent current of 80 uA. Accuracy is specified at 1.5%, with a reset delay time of 3 ms. It operates within a commercial temperature range of 0°C to +70°C.
