The MAX6397SATA+ is a precision voltage monitoring integrated circuit manufactured by Maxim Integrated. It features a single-channel supervisor with an open-drain or open-collector output configuration housed in an 8-TDFN package measuring 3x3 millimeters. Designed to monitor power supplies and systems, the device has a fixed threshold voltage of 2.892 volts and provides an active-low output to signal when the monitored voltage drops below this threshold. The compact form factor and reliable performance make it suitable for space-constrained electronic designs requiring accurate voltage supervision.
