The CAT1026WI-28-GT3 from ON Semiconductor is a dual voltage supervisory circuit designed for microcontroller-based systems. It integrates a system power supervisor with brown-out protection and a 2k-bit serial EEPROM memory, communicating via a 400 kHz I2C bus.
This supervisor IC offers precision VCC monitoring with five reset threshold voltage options supporting 5 V, 3.3 V, and 3 V systems. It provides an externally adjustable voltage monitoring down to 1.25 V. The reset function is active high or low, with a guaranteed valid reset at VCC = 1 V and a reset timeout of 130ms minimum. The output is configurable as open drain or open collector.
Operating within a 2.7 V to 5.5 V range, the CAT1026WI-28-GT3 is built with low-power CMOS technology. It is housed in an 8-SOIC package with surface mount capability. The operating temperature range is -40°C to 85°C (TA).
This device protects memory and system controllers during power up/down and against brownout conditions. If power supply voltages fall out of tolerance, reset signals become active, preventing system malfunction. The CAT1026 features two open drain reset outputs, while the CAT1027 includes a watchdog timer.
