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_CC = 3 V)
• Wide supply voltage range: V_CC(max) = 7 V
Application
• Supervisor for microcontroller systems
Recommended Operating Condition
• Recommended supply voltage: 3 V
