Overview
TSC102 High-side current sense amplifier plus signal conditioning amplifier P TSSOP8 (plastic package) D SO8 (plastic package) Vm 1 Gnd 2 A1 3 A2 4 Pin connections (top view) 8 Vp 7 A3 6 Vcc 5 Out Features • Independent supply and input common-mode voltages • Wide common-mode operating range: 2.
8 to 30 V • Wide common-mode surviving range: -16 to 60 V (reversed battery and load-dump conditions) • Low current consumption: ICC max = 420 µA Datasheet - production data • Output amplifier for tailor-made signal conditioning • -40 °C to 125 °C operating temperature range • 4 kV ESD protection Applications • Battery chargers • Automotive current monitoring • Notebook computers • DC motor control • Photo-voltaic systems • Precision current sources • Uninterruptible power supplies • High-end power supplies Description The TSC102 measures a small differential voltage on a high-side shunt resistor and translates it into a ground-referenced output voltage.
The device’s wide input common-mode voltage range, low quiescent current and tiny TSSOP8 packaging enable use in a wide variety of applications (also available in SO8 package).
The input common-mode and power supply voltages are independent.
The common-mode voltage can range from 2.
8 to 30 V in operating conditions.
The TSC102 is rugged against abnormal conditions on the input pins: Vp and Vm can withstand up to 60 V in case of voltage spikes, as little as -16 V in case of reversed battery, and up to 4 kV in case of electrostatic discharge.
In addition to the current sensing amplifier, the TSC102 offers a fully accessible amplifier for output signal conditioning.
The device’s overall current consumption is lower than 420 µA.
