Hot-selling and scarce IMP706SEPA 3/3.3/4.0V 3/3.3/4.0V µP Supervisor Circuits DIP8 spot stock

Product Descriptions

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 areset  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.
