5-Pin µP Supervisory Circuits with

Watchdog and Manual Reset

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

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.
