Current sense amplifiers

High voltage, low- and high-side current sense amplifiers

A high-side current sense amplifier which delivers an analog voltage output; the TSC200 integrates an open-drain comparator with output latch function and an internal 0.6 V voltage reference.

High-voltage, low- and high-side bidirectional current sense amplifiers

Able to detect drop voltages as low as 10 mV, our high-voltage bidirectional current sense amplifiers (available both as Automotive and Industrial grade) can sense the current thanks to a shunt resistor over a wide range of common mode voltages from –20 to + 70 V, regardless of the supply voltage. Available also with extended temperature range (-40 to 150 °C).
