TSC102 High-side current sense amplifier plus signal conditioning amplifier Datasheet - production data Output amplifier for tailor-made signal conditioning -40 C to 125 C operating temperature range 4 kV ESD protection P Applications TSSOP8 Battery chargers (plastic package) Automotive current monitoring Notebook computers DC motor control Photo-voltaic systems Precision current sources D Uninterruptible power supplies SO8 High-end power supplies (plastic package) Description The TSC102 measures a small differential voltage Vm 1 8 Vp on a high-side shunt resistor and translates it into Gnd 2 7 A3 a ground-referenced output voltage. The devices wide input common-mode voltage A1 3 6 Vcc range, low quiescent current and tiny TSSOP8 A2 4 5 Out packaging enable use in a wide variety of applications (also available in SO8 package). Pin connections The input common-mode and power supply (top view) voltages are independent. The common-mode voltage can range from 2.8 to 30 V in operating conditions. Features The TSC102 is rugged against abnormal conditions on the input pins: Vp and Vm can Independent supply and input common-mode withstand up to 60 V in case of voltage spikes, as voltages little as -16 V in case of reversed battery, and up Wide common-mode operating range: to 4 kV in case of electrostatic discharge. 2.8 to 30 V In addition to the current sensing amplifier, the Wide common-mode surviving range: TSC102 offers a fully accessible amplifier for -16 to 60 V (reversed battery and load-dump output signal conditioning. The devices overall conditions) current consumption is lower than 420 A. Low current consumption: I max = 420 A CC January 2014 DocID16754 Rev 3 1/23 This is information on a product in full production. www.st.comContents TSC102 Contents 1 Application schematic and pin description 3 2 Absolute maximum ratings and operating conditions . 4 3 Electrical characteristics . 5 4 Electrical characteristics curves: current sense amplifier 8 5 Electrical characteristics curves: signal conditioning amplifier 11 6 Parameter definitions . 12 6.1 Common-mode rejection ratio (CMR) . 12 6.2 Supply voltage rejection ratio (SVR) 12 6.3 Gain (Av) and input offset voltage (V ) 12 os 6.4 Output voltage drift versus temperature 13 6.5 Output voltage accuracy 15 7 Application information . 16 8 Package information 19 8.1 TSSOP8 package information . 20 8.2 SO8 package information . 21 9 Ordering information . 22 10 Revision history . 22 2/23 DocID16754 Rev 3
