• Manufacturer Part Number: sp000278512
• Description: Differential Two-wire Hall Effect Sensor Ic
• Manufacturer: Infineon Technologies Corporation

Speed pulse occur only at the first pulse after start up or above
If no magnetic differential signal change is detected the IC will remain in calibrated mode.
No internal reset are generated - therefore a zero speed operation is possible.
