The MAX9610HELT+T from Maxim Integrated Products is a lithium-ion battery, precision current sense amplifier in 6 pin µDFN package. This high side current sense amplifier offers precision accuracy specifications of VOS less than 500µV (max) and gain error less than 0.5% (max). This device features an ultra low 1µA quiescent supply current and fits in a tiny package making device ideal for applications in notebook computers, cell phones, cameras, PDAs and all lithium-ion (Li+) battery-operated portable devices where accuracy, low quiescent current and small size are critical. The input voltage range is excellent for monitoring the current of a single-cell, lithium-ion battery which at full charge is 4.2V, typically 3.6V in normal use and less than 2.9V when ready to be recharged.
Single supply range from 1.6V to 5.5V
Operating temperature range from -40°C to 85°C
100V/V gain
Low 500µV (max) input offset voltage
Low < 0.5% (max) gain error
3.3V and 5V Power Management Systems; Cameras; Cell Phones; PDAs; Portable Li+ Battery Powered Systems; USB Ports
