CAT1641WI-42-TE13

Supervisors Overview

The CAT1641WI-42-TE13 is a voltage supervisory circuit manufactured by onsemi, designed for CPU monitoring applications. It operates within a supply voltage range of 3 V to 5.5 V and features a fixed threshold voltage of 4.2 V. The device provides one monitored input with an active high, open drain output type. It includes manual reset functionality but lacks a watchdog timer or battery backup switch. The reset delay time is specified at 270 ms, and the quiescent current is 3 mA. It supports overvoltage detection at 4.5 V and dissipates up to 1 W of power. The component is housed in an SOIC-8 package and functions reliably across an operating temperature range from -40°C to +85°C.
