ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(Circuit of Figure 2, VIN = 1.2V, ILOAD = 0mA, TA = +25°C, unless otherwise noted.)

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.

Supply Voltage (OUT to GND) ...................................-0.3V, +7V

Reference Current (IREF) ..................................................2.5mA

Continuous Power Dissipation (TA = +70°C)

SO (derate 5.88mW/°C above +70°C) .........................471mW

µMAX (derate 4.1mW/°C above +70°C) ......................330mW

Reverse Battery Current (TA ≤ +45°C) (Note 1)................750mA

Operating Temperature Ranges

MAX86_C/D .......................................................0°C to +70°C

MAX86_E_A ....................................................-40°C to +85°C

Junction Temperature .....................................................+150°C

Storage Temperature Range ............................-65°C to +160°C

Lead Temperature (soldering, 10sec) ............................+300°C

Note 1: Reverse battery current is measured from the

Typical Operating Circuit’s battery input terminal to GND when the battery is

connected backwards. A reverse current of 750mA will not exceed the package dissipation limits but, if left for an extended

time (more than ten minutes), may degrade performance.
