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 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 re...
