Application schematics and pin description

The TSC888 high-side current-sense amplifier features a 2.8 V to 24 V input common-mode

range that is independent of supply voltage. The main advantage of this feature is to allow

TSC888 can therefore be supplied by a 5 Vsb line and monitor a 3.3 V, 5 V or 12 V power

line. Considering the wide supply voltage operating range (4 V to 24 V) another option
