... The MAX5091 includes an uncommitted comparator for input voltage monitoring/power-fail indication. The device is available with a fixed +5V (MAX5091A) or +3.3V (MAX5091B) output. The MAX5091 is short-cir- cuit protected and includes thermal shutdown. The MAX5091 operates over the -40°C to +125°C auto- motive temperature range and is available in 8-pin, thermally enhanced TDFN and SO-EP packages ...
