MIC706P/R/S/T, MIC708R/S/T
ВµP Supervisory Circuit General Description Features The MIC706 and MIC708 are inexpensive microprocessor
supervisory circuits that monitor power supplies in 3.0V
and 3.3V microprocessor-based systems. The circuit
functions include a watchdog timer, microprocessor reset,
power-failure warning, and a debounced manual reset
input. Maximum supply current: 30ВµA Debounced manual reset input is TTL/CMOS
compatible Reset pulse width: 200ms Watchdog timer: 1.6s (MIC706) Precision supply voltage monitor Easy power-fail warning or low-battery detect The MIC706 offers a watchdog timer function, while the
MIC708 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. Applications Laptop and desktop computers
Intelligent systems
Critical microprocessor power monitoring
Printers
