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 as high as 0.25%. The integrated dynamic offset cancellation circuit ensures that the sensitivity and static output voltage are almost unaffected by external pressure and packaging stress. The chopping frequency is 1.4MHz, the bandwidth is 240kHz, and the response speed is fast. 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.
