The MAX44286 is a zero-drift, high-side current-sense amplifier family that offers precision, low supply current and is available in a tiny 4-bump ultra-thin WLP of 0.78mm x 0.78mm x 0.35mm footprint. This miniature size is of paramount for today’s applications in smartphones, mobile accessories, notebooks, portable medical, and all battery-operated portable devices where current monitoring with precision and space are critical. The MAX44286 has voltage output offered in four gain versions of 25V/V, 50V/V, 100V/V, and 200V/V. These four gain versions offer flexibility in the choice of the sense resistor and the very low input offset voltage helps in detecting small currents on the orders of low microamps. Low power capability also offers the possibility of minimizing power dissipation. The MAX44286 operates with a supply voltage range of 1.6V to 5.5V over the -40°C to +85°C temperature range and from 1.8V to 5.5V over the -40°C to +125°C automotive temperature range. Supply voltage for the device is shared with the RS+ pin to fit the MAX44286 in a 4-bump, ultra-thin WLP package.
