CC6900 Fully Integrated, Hall Effect-Based Linear Current Sensor IC with a Low-Resistance Conductor

PublishTime：2020-07-17

The CC6900 device is an electrically isolated monolithic current sensor based on Hall Effect.The device provides precise and economical solutions for AC or DC current sensing in industrial,commercial and communication equipments. It is provided in a small,surface mount SOP8 package with current sensing range of 5A/10A/20A/30A.Customers can easily complete their PCB design and implementation.
The CC6900 device consists of a precise,low-offset,linear Hall circuit with a copper conduction path located near the surface of the die.When current flows through the copper conduction path,a magnetic field generates.Meanwhiles the Hall circuit converts this magnetic signal to output voltage signal.
The Hall circuit based on BiCOMS process integrates a high sensitivity Hall element,oscillator,Hall signal pre-amplifier,CrossChip^®patented temperature compensation circuit,dynamic offset cancellation circuit,sensitivity trimming circuit and output amplifier.The temperature compensation circuit ensures good temperature stability of CC6900.Chopper stabilization technique is applied to the Hall circuit to minimize offset voltage.High chopping frequency up to 1MHz makes CC6900 80kHz band width and ultra-short step input response time down to typical 2 us.Because of this chopper stabilization approach,the output voltage from the Hall IC is desensitized to the effects of temperature and mechanical stress.
Internal copper conductor’s resistance is typical 1.5mΩ,which provides much less power loss than the universal resistor sampling method.
Zero current output voltage is 50%VCC.When power supply voltage is 5V,the linear output voltage range is 0.2~4.8V,a range of 0.5~4.5V is recommended for better linearity.
Current sensing range of CC6900 is programmed to a fixed value after packaging,and the range of 5A/10A/20A/30A is available.It’s operating ambient temperature range is -40~125°C.
