Description

This electronic component model is the IMP708TESA, belonging to the product category of IC Chips. It is a µP Supervisor Circuit with a low supply current, a watchdog timer, and brownout detection. The IMP706P/R/S/T/J and IMP708R/S/T/J CMOS supervisor circuits monitor power-supply and battery voltage levels, as well as µP/µC operation. A reset signal is generated when the supply drops below specific thresholds for each variant of the device. This component family offers several functional options, including generating reset signals during power-up, power-down, and brownout conditions.
