CC6902SO-5A current detection verification board

CC6902 is a high-performance single-ended output linear current sensor that can be used as a more effective alternating current (AC) or direct current (DC) current detection solution. It is widely used in industrial, consumer
and communication equipment.

CC6902 internally integrates a high-precision, low-noise linear Hall circuit and a low-impedance main current lead. When the sampling current flows through the main current wire, the magnetic field generated by it
induces a corresponding electrical signal on the Hall circuit, and the voltage signal is output through the signal processing circuit, making the product easier to use. The linear Hall circuit is produced using an advanced BiCMOS process and includes
a high-sensitivity Hall sensor, a Hall signal preamplifier, a high-precision Hall temperature compensation unit, an oscillator, a dynamic offset cancellation circuit and an amplifier output module. In the absence of a magnetic field,
the static output is 50%VCC.

Under the condition of power supply voltage 5V, OUT can change linearly with the magnetic field between 0.2~4.8V, and the linearity can reach 0.4%. The dynamic offset cancellation circuit integrated within the CC6902 makes the IC's
sensitivity unaffected by external pressure and IC packaging stress.
