IMP706P

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 competitive 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 compact MicroSO packages. The MicroSO package requires 50% less PC board area than the conventional SO package.
