MIC706P/R/S/T, General Description
The MIC706P/R/S/T and MIC708R/S/T are inexpensive microprocessor supervisory circuits that monitor power supplies in 3.0 and 3.3 Volt microprocessor based systems. The circuit functions include a watchdog timer, microprocessor reset, power failure warning and a debounced manual reset input.
The MIC706 offers a watchdog timer function, while the MIC708 has no watchdog timer but has an active high reset output in addition to the active low reset output.
The R, S, and T versions are similar in all respects except for supply voltage reset threshold levels. The threshold levels are 2.63, 2.93, and 3.08V respectively. When the supply voltage drops below the reset threshold level, /RESET (and RESET for the MIC708) is asserted.
The MIC706P is identical to the MIC706R, except that the Reset output is asserted high.
