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 out-

puts 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.
