M62050P,FP

3V supply SYSTEM RESET with watchdog timer

GENERAL DESCRIPTION

M62050P/FP is a voltage threshold detector designed for detection

of 3V 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 0.6mA (typ) during normal operations of the MCU systems.

It has 2 selectable threshold voltages, which allows applying it to a

high precision system design.

FEATURES

• Watchdog timer (supervisor for 2 system voltages)

• Power-on reset timer

• Low current consumption 0.6mA (typ) at Vcc = 3V

• Wide supply voltage range Vcc = 7V (max)

APPLICATION

• Supervisor for microcontroller systems

RECOMMENDED OPERATING CONDITION

• Supply voltage range

2V ~ 4V
