SC4643 Programmable High Precision Linear Hall Sensor IC



SC4643 is a programmable liner Hall-effect sensor IC, integrated with one magnetic sensor module, a three-level variable low-noise amplifier, output pin and temperature detection, quiescent output compensation, sensitivity compensation, and EEPROM. The sensor reacts to the magnetic field which is perpendicular to the chip, and convert to output voltage according to sensitivity. Which is very suitable to current monitor.
SC4643 have a quiescent output voltage default as half of the supply voltage. And the quiescent voltage can be programmed through supply voltage and output-pin. The sensitivity range of the chip can be shifted from 0.6mV/Gs to 14mV/Gs in order to adapt the current flow of various ranges.
SC4643 is integrated with temperature sensor module. User can compensate the sensitivity of the chip through programmable algorithm, together with the temperature coefficient of the magnetic ring could enhance accuracy.
The typical supply-voltage of the IC is 5.0V , limited voltage is 15V, operating temperature is -40℃ to 150℃, capable of maintaining stable operation in the harsh automotive environment.
The SC4643 sensor IC is available in a 4-pin SIP The package is lead (Pb) free, with 100% matte tin plating.
