Semiment SC4643VB-BK-Q

This programmable linear Hall sensor IC integrates a magnetic field sensing element, a three-stage variable-gain low-noise amplifier, an output stage, temperature detection, quiescent output compensation, sensitivity compensation, and an EEPROM control module. It senses magnetic fields perpendicular to the chip surface and converts them to a proportional voltage output scaled by sensitivity, making it well suited for current sensing applications. The quiescent output voltage defaults to half the supply voltage and can be calibrated online via the supply and output pins to meet application requirements. The sensitivity is adjustable over a range of 0.6~14mV/Gs to accommodate current sensing across different measurement ranges. The integrated temperature sensor module allows users to adjust the temperature coefficient to compensate for sensitivity variation with temperature, working in conjunction with the magnetic core's temperature characteristics to improve overall sensor accuracy. The typical operating voltage is 5.0V, with a maximum voltage rating of 15V and an operating temperature range of -40~150℃, meeting the demanding requirements of automotive electronics environments. The sensor is available in TO92U and TO94 packages with matte tin plating and halogen-free green compound, compliant with environmental regulations.
