MCU监控芯片/IMP708EPA 管装
– Watchdog timer
– Brownout detection
– Power supply monitor
The 705/706/707/708 and IMP813L CMOS supervisor circuits monitor power-supply and battery voltage level, and µP/µC operation. Compared to pin-compatible devices offered by Maxim Integrated Products, IMP devices feature 60 percent lower maximum supply current. The family offers several functional options. Each device generates a reset signal during power-up, power-down and during brownout conditions. A reset is generated when the supply drops below 4.65V IMP705/707/813L or 4.40V IMP706/708. For 3V power supply applications
