Overview CC6537 integrates an on-chip Hall sensor, using a 0.18um process to achieve an integrated design of 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. CC6537 uses advanced adaptive Hall temperature compensation technology and can operate normally between -40°C and 125°C. It has a wide linear output range; under a 5V power supply, 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. The chopping frequency is 1.4MHz, the bandwidth is 240kHz, and the response speed is fast. The chip integrates an E-fuse, which can be programmed twice. CC6537 supports zero-point adjustment, gain adjustment, polarity adjustment, reverse connection protection, and open-circuit protection. It features temperature compensation, offset voltage, and linearity calibration; high and low-temperature calibrations are completed at the chip level. CC6537 is available in a TO-94 package, with an operating temperature range of -40°C to 125°C and a storage temperature range of -40°C to 165°C. It meets environmental requirements such as halogen-free, lead-free, and RoHS regulations.
