EM6353BZ2SP3B-2.9+

Supervisors Overview

The EM6353BZ2SP3B-2.9+ is a reset circuit manufactured by EM Microelectronic-Marin SA, designed for power management applications. It monitors supply voltage and generates a reset signal when the voltage drops below a specific threshold. The device operates with power supplies between 1.5V and 5.5V and features an ultra-low supply current of 2.9μA at VDD = 3.3V. It offers three output types: active-low push-pull, active-low open-drain, and active-high push-pull. The circuit includes an adjustable reset timeout period using an external capacitor and provides high accuracy with ±1.5% reset threshold tolerance.
