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.

RTI stands for “Related to input”. 2. Offset is extrapolated from measurements of the output at VSense of 20 mV and 100 mV. 3. Total output error considers effects of gain error and VOS inaccuracy. 4. The TSC200 is designed to power up with the comparator in a defined reset state as long as RESET is open or grounded. The comparator is in reset as long as the power supply is below the voltage shown here. The comparator assumes a state based on the comparator input above this supply voltage. If RESET is high at power-up, the comparator output comes up high and requires a reset to assume a low state, if appropriate. DS13882 - Rev 1 page 5/18 TSC200 Electrical characteristics Table 5.
