This power management IC is a CPU supervisor featuring a 2 kbit EEPROM memory. It monitors a single voltage with a reset threshold between 4.25V and 4.5V, offering active high/low reset output and a 130ms reset timeout. The component includes a watchdog timer and operates from a 2.7V to 5.5V supply, drawing a maximum of 3mA. Packaged in a PDIP-8 (300 mils) through-hole mount, this halogen-free, lead-free, and RoHS-compliant device has a maximum power dissipation of 1W and an operating temperature range of -40°C to 85°C.
