TSC1031 High-voltage, high-side current sense amplifier Datasheet - production data Low current consumption: I max = 360 A CC Pin selectable gain: 50 V/V or 100 V/V Buffered output EMI filtering TSSOP8 (Plastic package) Applications Automotive current monitoring DC motor control Photovoltaic systems Battery chargers Precision current sources SO-8 Current monitoring of notebook computers (Plastic package) Uninterruptible power supplies High-end power supplies Description The TSC1031 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage. The TSC1031s dedicated schematic eases the implementation of EMI filtering in harsh environments. The gain is adjustable to 50 V/V or Pin connections 100 V/V by a selection pin. (top view) Wide input common-mode voltage range, low quiescent current, and tiny TSSOP8 packaging Features enable use in a wide variety of applications. The input common-mode and power supply Independent supply and input common-mode voltages are independent. The common-mode voltages voltage can range from 2.9 to 70 V in the single- Wide common-mode operating range: supply configuration or be offset by an adjustable 2.9 to 70 V in single-supply configuration voltage supplied on the Vcc- pin in the dual- -2.1 to 65 V in dual-supply configuration supply configuration. Wide common-mode surviving range: With a current consumption lower than 360 A -16 to 75 V (reversed battery and load-dump and a virtually null input leakage current in conditions) standby mode, the power consumption in the Supply voltage range: applications is minimized. 2.7 to 5.5 V in single supply configuration March 2014 DocID016875 Rev 3 1/26 This is information on a product in full production. www.st.comContents TSC1031 Contents 1 Application schematic and pin description 3 2 Absolute maximum ratings and operating conditions . 6 3 Electrical characteristics . 7 4 Electrical characteristics curves: current sense amplifier . 10 5 Parameter definitions . 13 5.1 Common mode rejection ratio (CMR) 13 5.2 Supply voltage rejection ratio (SVR) 13 5.3 Gain (Av) and input offset voltage (V ) 13 os 5.4 Output voltage drift versus temperature 15 5.5 Input offset drift versus temperature . 16 5.6 Output voltage accuracy 16 6 Maximum permissible voltages on pins 18 7 Application information . 19 8 Package information 21 8.1 SO-8 package information 22 8.2 TSSOP-8 package information . 23 9 Ordering information . 24 10 Revision history . 25 2/26 DocID016875 Rev 3
