Cross chip CC6538T4S-002BF5-RE-AC

CC6538 integrates Hall on a chip and adopts BCD process to achieve the integrated design of Hall and signal conditioning ASIC circuits. The chip contains a high-sensitivity Hall sensor, a Hall signal preamplifier, a high-precision Hall temperature compensation unit, oscillator, dynamic offset cancellation circuit and amplifier output module. CC6538 adopts advanced adaptive hall temperature compensation technology, which can work normally between -40~150℃. It has a wide linear output range. Under the power supply voltage of 5V, VOUT output can vary linearly with magnetic field between 0.5~4.5V and the linearity is up to 0.25%. Due to the integrated dynamic offset cancellation circuit, the sensitivity and quiescent output voltage are not affected by external pressure and packaging stress. The IC has the advantages of chopping frequency of 1.4MHz, bandwidth of 240kHz fast response speed and so on. The chip integrates E-fuse, which can be programmed twice and has a fuse lock function. The CC6538 has the functions of zero point adjustment, gain adjustment, polarity adjustment, reverse polarity protection and break circuit protection. Temperature compensation and linearity calibration, high and low temperature calibration is completed at the chip level. CC6538 provides TO-94 package with operating temperature range of -40~150℃ and storage temperature range -40~165℃, comply with halogen-free, lead-free and RoHS requirements.
