ML7005 DTMF Transceiver ML7005DTMF Transceiver

The MLX90224 series consists of dual Hall effect latches. It features two Hall effect latch functions with typical thresholds of +/- 2.0 mT. Each latch utilizes a switched silicon Hall plate for magnetic flux detection. The BOP and BRP are temperature-compensated, providing a sensitivity temperature coefficient of 500 ppm/°C to counteract the effects of popular magnets. The MLX90224 A output transistor will latch on (BOP) when exposed to a sufficiently strong South pole magnetic field facing the marked side of the package. Conversely, the output will latch off (BRP) in the presence of a North field. The spacing on the plates is 1.85 mm. The MLX90224 B series is designed for direction detection and features a high-speed chopper that provides a 15 ms delay.

The MLX90224 series Hall effect latches are integrated circuits designed for precise magnetic field sensing applications. Each latch in the series operates based on the Hall effect principle, where a magnetic field applied perpendicular to the current flow in a conductor generates a voltage difference. The two latches in the MLX90224 series are configured to respond to opposing magnetic polarities, enhancing versatility in various applications.

The sensitivity thresholds of +/- 2.0 mT allow the device to detect relatively weak magnetic fields, making it suitable for applications such as position sensing, speed detection, and proximity sensing in consumer electronics, automotive systems, and industrial automation. The temperature compensation feature ensures stable operation across a wide temperature range, mitigating the impact of temperature variations on the magnetic sensing performance.

The MLX90224 A variant is particularly useful for applications requiring a reliable response to a South pole magnetic field, while the MLX90224 B variant enhances functionality by incorporating a high-speed chopper. This chopper mechanism allows for rapid toggling between states, with a specified delay of 15 ms, facilitating direction detection in dynamic environments where the magnetic field may change quickly.

The physical design of the MLX90224 series includes a spacing of 1.85 mm between the Hall plates, which is optimized for effective magnetic field detection while maintaining compact dimensions suitable for integration into space-constrained applications. The output transistors are designed to provide robust switching capabilities, ensuring reliable performance in various operational conditions. Overall, the MLX90224 series provides a comprehensive solution for magnetic sensing needs, combining sensitivity, temperature stability, and directional detection capabilities.The MLX90224 series are dual Hall effect Latches It includes two Hall effect latch functions of which typical thresholds are +/- 2. 0 mT.
