STMicroelectronics TSC202→TSC202IDT

The TSC200, TSC201 and TSC202 are high-side current sense amplifiers which deliver an analog voltage output. They 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. They are available with an amplification gain of 20 V/V for TSC200, 50 V/V for TSC201, and 100 V/V for TSC202.

The TSC200, TSC201 and TSC202 integrate an open-drain comparator with output latch function and an internal 0.6 V voltage reference connected to its input. The external resistor divider can then set the switching threshold.

These devices fully operate over the broad supply voltage range of 2.7 to 18 V and over the automotive temperature range of -40 to +125 °C.
