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
