Two-Wire Current PWM Output High Accuracy Speed Sensor IC
Utilizing a high-voltage BiCMOS process, it achieves high EMC immunity, along with excellent stability in precision and sensitivity.
SC9642 is a two-wire current output wheel speed sensor based on pulse width modulation (PWM) principle, which can provide speed, rotation direction and installation distance information. The chip adopts the high-pressure BiCMOS process, that can achieve high EMC protection ability, and the accuracy and sensitivity are relatively stable at full temperature, which is very suitable for the harsh automotive electronic environment.
