ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

= -25°C to +50°C.) (Note 1)

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.

Note 1: System requirement.

Note 2: Measured from the time at which the incident field is present with strength greater than or equal to H

(MIN)

to the time at

which the MAX66020’s internal power-on reset signal is deasserted and the device is ready to receive a command frame.

Not characterized or production tested; guaranteed by simulation only.
