Key Features
x Lower power, pin compatible replacements for Maxim MAX706P/R/S/T, MAX708R/S/T – 30% lower supply current:140A vs. 200A x Precision power supply monitor – 2.63V threshold (IMP706P/R, IMP708R) – 2.93V threshold (IMP706S, IMP708S) – 3.08V threshold (IMP706T, IMP708T) – New 4.00V threshold (IMP706J, IMP708J) x Debounced manual reset input x Auxiliary voltage monitor comparator – 1.25V threshold – Battery monitor/auxiliary supply monitor x Watchdog timer (IMP706P/R/S/T/J) – Watchdog can be disabled by floating WDI x 200ms reset time delay x Three reset signal options – Active HIGH: IMP706P – Active LOW: IMP706R/S/T/J – Active HIGH & LOW outputs: IMP708R/S/T/J x DIP, SO and MicroSO packages x Guaranteed RESET assertion to VCC = 1.1V
The IMP706P/R/S/T/J and IMP708R/S/T/J CMOS supervisor circuits monitor power-supply and battery voltage level, and P/C operation. A reset is generated when the supply drops below 2.63V (IMP706P/R, IMP708R), 2.93V (IMP706S, IMP708S), 3.08V (IMP706T, IMP708T) or 4.00 (IMP706J, IMP708J). The family offers several functional options. Each device generates a reset signal during power-up, power-down and during brownout conditions. In addition, the IMP706P/R/S/T/J feature a 1.6 second watchdog timer. The watchdog timer output will trigger a reset if connected to MR. Unlike competitive devices, flo……
