General Description The MAX6361–MAX6364 supervisory circuits reduce the complexity and number of components required for power-supply monitoring and battery control functions in microprocessor (µP) systems. The circuits significantly improve system reliability and accuracy compared to that obtainable with separate ICs or discrete components. Their functions include µP reset, backup battery switchover, and power failure warning. The MAX6361–MAX6364 operate from supply voltages as low as +1.2V. The factory-preset reset threshold voltage ranges from 2.32V to 4.63V (see Ordering Information). These devices provide a manual reset input (MAX6361), watchdog timer input (MAX6362), battery-on output (MAX6363), and an auxiliary adjustable reset input (MAX6364). In addition, each part type is offered in three reset output versions: an active-low open-drain reset, an active-low open-drain reset, and an active-high open- drain reset (see Selector Guide at end of data sheet). Applications Features ♦ Low +1.2V Operating Supply Voltage (VCC or VBATT) ♦ Precision Monitoring of +5.0V, +3.3V, +3.0V, and +2.5V Power-Supply Voltages ♦ Debounced Manual Reset Input (MAX6361) ♦ Watchdog Timer with 1.6s Timeout Period (MAX6362) ♦ Battery-On Output Indicator (MAX6363) ♦ Auxiliary User-Adjustable RESET IN (MAX6364) ♦ Three Available Output Structures Push-Pull RESET, Open-Drain RESET, Open-Drain RESET ♦ RESET/RESET Valid Down to 1.2V Guaranteed (VCC or VBATT) ♦ Power-Supply Transient Immunity ♦ 150ms (min) Reset Timeout Period ♦ Small 6-Pin SOT23 Package SOT23, Low-Power µP Supervisory Circuits with Battery Backup ________________________________________________________________ Maxim Integrated Products 1 19-1615; Rev 3; 11/05 Ordering Information Pin Configurations Note: These parts offer a choice of reset threshold voltages. From the table below, select the suffix corresponding to the desired threshold voltage and insert it into the part number to complete it. When ordering from the factory, there is a 2500- piece minimum on the SOT package (tape-and-reel only). Devices are available in both leaded and lead-free packaging. Specify lead-free by replacing "-T" with "+T" when ordering.
