– Watchdog timer

– Brownout detection

– Power supply monitor

The IMP705/706/707/708 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
