2 / 14 page MAX6316–MAX6322 5-Pin µP Supervisory Circuits with Watchdog and Manual Reset 2 Maxim Integrated ELECTRICAL CHARACTERISTICS (VCC = 2.5V to 5.5V, TA = -40°C to +125°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1) ABSOLUTE MAXIMUM RATINGS Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Voltage (with respect to GND) VCC......................................................................-0.3V to +6V RESET (MAX6320/MAX6321/MAX6322 only)...... -0.3V to +6V All Other Pins.........................................-0.3V to (VCC + 0.3V) Input/Output Current, All Pins .............................................20mA Continuous Power Dissipation (TA = +70°C) SOT23 (derate 7.1mW/°C above +70°C)...............571mW Operating Temperature Range..........................-40°C to +125°C Junction Temperature ......................................................+150°C Storage Temperature Range..............................-65°C to +160°C Lead Temperature (soldering, 10s) .................................+300°C Soldering Temperature (reflow) Leaded Package .........................................................+240°C Lead-Free Package .....................................................+260°C Note 1: Overtemperature limits are guaranteed by design, not production tested. Note 2: A factory-trimmed voltage divider programs the nominal reset threshold (VTH). Factory-trimmed reset thresholds are available in 100mV increments from 2.5V to 5V (see Table 1 at end of data sheet). Note 3: Guaranteed by design.
