current sense amplifierTouchstone Semiconductor, Inc. announced the TS1101, a bidirectional, symmetrical, high-side current-sense amplifiers (CSA). The TS1101 consumes 1 µA, a 30 times reduction over the closest competing product, according to the company. Its symmetrical architecture eliminates the “dead band” when switching from measuring battery discharge to measuring battery charge. This is said to significantly simplify customer designs while, at the same time, reducing power, saving board space and improving system accuracy. Input offset voltage is 100 µV, which the company claims is a four-times improvement over the closest competing part. The TS1101 is available in four gain options from 25 V/V to 200 V/V.

The TS1101 appropriate for low current, high-side current-sensing amplification in applications such as battery-powered and portable devices, including mobile phones, notebook computers, power management systems, motor control, load protection, current-shunt measurement and smart battery packs and chargers.
