LTC2900-1C Datasheet PDF - Linear Technology

DESCRIPTION
The LTC®2900 is a programmable supply monitor for systems with up to four supply voltages. One of 16 preset or adjustable voltage monitor combinations can be selected using an external resistor divider connected to the program pin. The preset voltage thresholds are accurate to ±1.5% over temperature.
