CAT1640YI-45-GT3

Supervisors Overview

The CAT1640YI-45-GT3 is a voltage supervisory circuit manufactured by onsemi, designed for monitoring single input voltages in electronic systems. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed threshold voltage of 4.5 V. The device provides an overvoltage detection capability at 4.75 V and includes a manual reset function alongside a watchdog timer. It utilizes an open drain or open collector output type and is housed in an 8-TSSOP surface-mount package with a width of 4.40 mm.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality for user-initiated control
• Features open drain or open collector output configuration

Supervisors Applications
