Description

The TSC200 is a high-side current sense amplifier which delivers an analog voltage

output. It can sense current via a shunt resistor over a wide range of common mode

voltages, from -16 to +80 V, whatever the supply voltage is. It is available with an

amplification gain of 20 V/V.

The TSC200 integrates an open-drain comparator with output latch function and an

internal 0.6 V voltage reference connected to its input. External resistor divider can

then set the switching threshold.

This device fully operates over the broad supply voltage range of 2.7 to 18 V and

over the industrial temperature range of -40 to +125 °C.

Applications

? High-side current sensing

? Low-side current sensing
