Overview The CC6538 integrates an on-chip Hall sensor, using a BCD process to achieve an integrated design of the Hall and signal conditioning ASIC circuits. The chip 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. The CC6538 uses advanced adaptive Hall temperature compensation technology and can operate normally between -40°C and 150°C. It has a wide linear output range; under a 5V power supply voltage, the VOUT output can linearly change between 0.5V and 4.5V with the magnetic field, with linearity up to 0.25%. The integrated dynamic offset cancellation circuit ensures that sensitivity and static output voltage are almost unaffected by external pressure and packaging stress. With a chopping frequency of 1.4MHz, a bandwidth of 240kHz, and fast response speed. The chip integrates an E-fuse, programmable twice with fuse locking function. The CC6538 supports zero-point adjustment, gain adjustment, polarity adjustment, reverse connection protection, and open-circuit protection. It features temperature compensation and linearity calibration, with high and low-temperature calibration completed at the chip level. The CC6538 is available in a TO-94 package, with an operating temperature range of -40°C to 150°C and a storage temperature range of -40°C to 165°C. It meets relevant environmental protection requirements such as halogen-free, lead-free, and RoHS.
