1 / 25 page  This is information on a product in full production. January 2014 DocID16873 Rev 3 1/25 TSC103 High-voltage, high-side current sense amplifier 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: ICC max = 360 µA • Pin selectable gain: 20 V/V, 25 V/V, 50 V/V or 100 V/V • Buffered output Applications • Automotive current monitoring • DC motor control • Photo-voltaic systems • Battery chargers • Precision current sources • Current monitoring of notebook computers • Uninterruptible power supplies • High-end power supplies Description The TSC103 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.
