Description
The TSC1021 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The TSC1021 has been specifically designed for automotive conditions: load-dump protection up to 60 V, reverse-battery protection up to -32 V, ESD protection up to 4 kV and internal filtering for EMI performance. Input common-mode and power supply voltages are independent: the common-mode voltage can range from 2.8 to 30 V in operating conditions and up to 60 V in absolute maximum ratings while the TSC1021 can be supplied by a 5 V independent supply line. The TSC1021 is housed in a tiny TSSOP8
