Image of STMicroelectronics TSC200 Current Sense Amplifier STMicroelectronics' TSC200 is a high-side current sense amplifier that delivers an analog voltage output. It can sense current via a shunt resistor over a wide range of common mode voltages, from -16 V to +80 V, whatever the supply voltage. It is available with an amplification gain of 20 V/V.

The TSC200 integrates an open-drain comparator with an output latch function and an internal 0.6 V voltage reference connected to its input. An external resistor divider can then set the switching threshold. This device fully operates over the broad supply voltage range of 2.7 V to 18 V and over the industrial temperature range of -40°C to +125°C.
