Description

The M62050P/FP is a voltage threshold detector designed for detection of 3 V supply voltage and generation of a

system reset pulse. It is suitable for microcontroller systems.

The IC, a supervisor of the MCU operations, dissipates low current of 0.6 mA (Typ) during normal operations of the

MCU systems.

It has two selectable threshold voltages, which allows applying it to a high precision system design.

Features

• Watchdog timer (supervisor for two system voltages)

• Power-on reset timer

• Low current consumption: 0.6 mA (Typ, V

• Wide supply voltage range: V

Application

• Supervisor for microcontroller systems

Recommended Operating Condition

• Recommended supply voltage: 3 V
