The LT6106 is a versatile high side current sense amplifier with features such as low cost, high accuracy, and wide input voltage range. It is suitable for automotive, industrial, and power management applications.
The LT6106 is a high‑side current‑sense amplifier with gain selectable by two external resistors. It offers low offset voltage (150 µV typical, 250 µV max), low input bias current (40 nA max), and a low supply current of 65 µA typical at 12 V. The device operates from 2.7 V to 36 V (44 V absolute max) and supports temperatures from –40 °C to 125 °C.
Typical applications include current shunt measurement, battery monitoring, power management, motor control, lamp monitoring, and over‑current fault detection. The datasheet includes detailed electrical characteristics, typical performance graphs, application guidelines, and package information for the 5‑lead TSOT‑23 (ThinSOT) package.
