CS30 High side current sense high voltage op amp Datasheet - production data Applications SOT23-5L (Plastic package) Wireless battery chargers Chargers for portable equipment Precision current sources Wearable Description Pin connection (Top view) The CS30 measures a small differential voltage on a high-side shunt resistor and translates it into a ground referenced output voltage. The gain is Out 1 5 Vcc internally fixed. Gnd 2 Wide input common-mode voltage range, low Vp 3 4 Vm quiescent current, and tiny SOT23 packaging enable use in a wide variety of applications. The input common-mode and power supply Features voltages are independent. The common-mode voltage can range from 2.8 to 30 V in operating Independent supply and input common-mode conditions and up to 60 V in absolute maximum voltages rating conditions. Wide common-mode operating range: 2.8 to The current consumption below 300 A and the 30 V wide supply voltage range enable the power Wide common-mode surviving range: - 0.3 to supply to be connected to either side of the 60 V (load-dump) current measurement shunt with minimal error. Wide supply voltage range: 4 to 24 V Low current consumption: I max = 300 A CC Internally fixed gain: 20 V/V, 50 V/V or 100 V/V Buffered output Table 1.
