TSC202IDT

TSC202IDT is a high-side current sense amplifier that delivers an analogue 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. The TSC202 integrates an open-drain comparator with an output latch function and an internal 0.6V voltage reference connected to its input. The external resistor divider can then set the switching threshold. Applications include high-side current sensing, low-side current sensing, overcurrent protection, automotive current sensing, telecom equipment, test and measurement equipment, industrial process control.
