Top-Side Heat Removal The 20mA active load facilitates fast contact testing when used in conjunction with the comparators, and functions as a pullup/pulldown for open-drain/collector DUT outputs. Ordering Information The PMU offers five current ranges from 2A to 50mA PART TEMP RANGE PIN-PACKAGE and can force and measure current or voltage. An SPI- MAX9979KCTK+ 0C TO +70C 68 TQFN-EP-IDP* compatible serial interface configures the MAX9979. +Denotes a lead(Pb)-free/RoHS-compliant package. The MAX9979 is available in a small footprint, 68-pin *EP-IDP = Exposed pad, inverted die pad. (10mm x 10mm x 1mm) TQFN-EP-IDP package with exposed pad on the top for easy heat removal. Power dis- sipation is 1.2W per channel (typ) over the full operating voltage range with the active load disabled. The MAX9979 Pin Configuration and Typical Operating Circuit appear at operates over an internal die temperature range of +40C end of data sheet to +100C and provides a temperature monitor output.

Actual maximum power dissipation is a function of heat extraction technique and may be substantially higher. 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.
