Description

The IMP708PESA is an electronic component model in the IC Chips product category. It belongs to the IMP705/706/707/708 family of CMOS supervisor circuits that monitor power supply and battery voltage level, as well as microprocessor (µP) and microcontroller (µC) operation. Compared to similar devices offered by Maxim Integrated Products, IMP devices have a 60 percent lower maximum supply current. This model generates a reset signal during power-up, power-down, and brownout conditions when the supply voltage drops below 4.65V (IMP705/707/813L) or 4.40V (IMP706/708). It is suitable for use in 3V power supply applications.
