Features N Lower power, pin patible replacements for Maxim MAX706P/R/S/T, MAX708R/S/T - 30% lower supply current:140µA vs. 200µA N 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) N Debounced manual reset input N Auxiliary voltage monitor parator - 1.25V threshold - Battery monitor/auxiliary supply monitor N Watchdog timer (IMP706P/R/S/T/J) - Watchdog can be disabled by floating WDI N 200ms reset time delay N Three reset signal options - Active HIGH: IMP706P - Active LOW: IMP706R/S/T/J - Active HIGH & LOW outputs: IMP708R/S/T/J N DIP, SO and Micro SO packages N 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 µP/µC 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 petitive devices, floating the WDI input pin disables the watchdog timer. The IMP708R/S/T/J have both active-HIGH and active-LOW reset outputs but no watchdog function. The IMP706P has the same pin-out and functions as the IMP706R but has an active-HIGH reset output. A versatile power-fail circuit, useful in checking battery levels and non-5V supplies, has a 1.25V threshold. All devices have a manual reset input. All devices are available in 8-pin DIP, SO and the pact Micro SO packages. The Micro SO package requires 50% less PC board area than the conventional SO package.
