1 / 24 page This is information on a product in full production. March 2014 DocID026041 Rev 1 1/24 CS70 High side current sense high voltage op amp Datasheet - production data Features Independent supply and input common-mode voltages Wide common-mode operating range: 2.9 V to 70 V in single-supply configuration, -2.1 V to 65 V in dual-supply configuration Wide common-mode surviving range: -16 V to 75 V (reversed battery and load-dump conditions) Supply voltage range: 2.7 to 5.5 V in single- supply configuration Low current consumption: I CC max = 360 µA Pin selectable gain: 20 V/V, 25 V/V, 50 V/V or 100 V/V Buffered output Applications Wireless battery chargers Chargers for portable equipment Precision current sources Wearable Description The CS70 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The gain is adjustable to four different values from 20 V/V up to 100 V/V by two selection pins. Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging enable use in a wide variety of applications. The input common-mode and power-supply voltages are independent. The common-mode voltage can range from 2.9 V to 70 V in the single- supply configuration or be offset by an adjustable voltage supplied on the Vcc- pin in the dual- supply configuration. With a current consumption lower than 360 µA and a virtually null input leakage current in standby mode, the power consumption in the applications is minimized. 2 1 3 SEL2 Vm SEL1 6 8 Gnd Vp 4 Out 7 Vcc- 5 Vcc+ TSSOP8 (Plastic package) Pin connections (top view) Table 1.
