Replacement for HAL1503, Hall switch GX503 in automobile transmission

Automobile automatic transmission can automatically change the transmission ratio according to the engine load, vehicle speed and other conditions, so that the car gets good power and fuel economy, and reduces engine emission pollution. The automatic transmission is simple to operate and can greatly improve the safety and reliability of the vehicle when the vehicle is congested.

Hall switch application in automatic transmission:

In automatic vehicles, the shift lever and transmission operate in a non-contact sensing mode. The shift lever transmits shift signals (also known as shift-by-wire) to the transmission via electronic signals.

To detect the position of the shifter in the transmission, a Hall sensor is recommended. It not only detects the position, but also sends a gear signal to the transmission.GXSC Hall SwitchThe GX503 is a high sensitivity unipolar Hall switch chip designed based on BCDMOS technology, which is ideally suited for automotive transmission applications.

The GX503 Hall switch includes temperature compensation, comparator and output driver, and mechanical stress has little effect on the magnetic parameters of the chip; in addition, the chip is available in three package forms: TO92S, Small-SOT23, SOT23-3L, and the package complies with ROHS standards. Its features are as follows:

- Low power consumption: 2.5mA

- Operating voltage: 2.7V~30V

- ESD up to: ± 12KV

- Strong anti-mechanical stress characteristics

- Temperature range: -40℃~150

- Power supply pin with reverse voltage protection

- Overvoltage protection up to 40V

- Compliance with AEC-Q100 automotive electronics industry test standards
