MAX708S General Description
The MAX708R/S/T are microprocessor supervisory circuits used to monitor +3 V power supply levels in +3 V to +5 V microprocessor and other logic systems. The R, S, T suffixes have reset thresholds of 2.63 V, 2.93 V and 3.08 V, respectively. They reduce the number of circuit components, and improve reliability and accuracy compared to using separate ICs or discrete components.
The MAX708R/S/T features make the MAX708R/S/T ideal for use in portable, battery operated equipment. The low supply current,typically 50 A, minimizes battery load. Both RESET and RESET are active during power-up, power-down and brownout conditions An active-LOW manual reset input is also available.
A 1.25 V threshold detector provides power-fail warning. This independent comparator can be used to monitor a second voltage supply and provide an early warning to the microprocessor that voltage is falling. This allows for an orderly shutdown, transmitting an alert to an operator, or activation of an alternate power source before the device asserts the reset signals.
The device is available in the 8-pin SO package.
