GENERAL DESCRIPTION
Customers can easily complete their PCB design and implementation. The CC6920B 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. Internal copper conductor’s resistance is typical 0.9mΩ, which provides much less power loss than the universal resistor sampling method. Otherwise, its internal inherent insulation provides 424VRMS basic working isolation voltage and 3500VRMS insulation withstand voltage between the input current path and the secondary circuit. 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. Zero current output voltage is 50%VCC.
