Speed Direction Detection（Anti-pinch window）
Features:
1. High voltage operation
2. Good consistency of magnetic parameters
3. High sampling frequency
4. Output overcurrent protection
Anti-pinch window working principle:
The Hall sensor detects the speed of the motor at any time. When the electric window is rising, if the speed of the electric motor slows down, the Hall sensor will detect a change in the speed and report the information to the ECU. Then the ECU will send an instruction to the relay, then the circuit will reverse the current to stop or reverse (fall) the motor, so that the window stops lifting, and achieving the anti-trap function.
Features:
-Dual output (dual speed version)
-Working voltage 2.7V~24V
-Environmental working temperature -40~150℃
-Power-on self-test
-Open drain output
-100KHz sampling frequency
-30V back pressure protection & over current protection
