Catalyst CAT1026 and CAT1027 Datasheet
The CAT1026 and CAT1027 provide precision Vcc monitoring and reset control for microcontroller‑based systems. They integrate a 2 k‑bit serial EEPROM and a power supervisor with brown‑out protection, operating over a 2.7 V to 5.5 V supply range.
Key features include five selectable reset thresholds, an auxiliary voltage monitor (Vsense), a watchdog timer on the CAT1027, and a variety of 8‑pin packages (DIP, SOIC, TSSOP, MSOP, TDFN). The devices are RoHS‑compliant and rated for industrial and extended temperature ranges.
