Phone with a magnetic switch Micropower Hall zero-power Hall IC sensor YHAL148

Custom processing: No Brand: HAL Model: HAL148 Category: reed tube (magnetron) Rated voltage: 2.4-5 (V) Rated current: 0 (A) Contact resistance: 0 (Ω) Insulation resistance: 0 (MΩ) Properties: Hot Marketing: Marketing Spot Price: Cheap I. Contents, divided unipolar Hall switch Hall switch (alternative reed), bipolar Hall switch, micropower all-pole ( Promise) of the Hall switch. 2, suitable for non-contact switch, car ignition, brake circuit, position, speed detection and control, security alarm devices, textile control system, speed, mileage, number of turns and reversible flow measurement, fishing gear, cell phones, instruments, cameras, flashlight ...... Second, third-party certification of the company's products can provide SGS products known Hall sensor HAL148 Omnipolar Hall switch Hall element a low-power, all-pole Hall switch 148 is a mixed-signal CMOS technology based Promise of Hall switches, this IC adopts advanced chopper stabilization technology, which can provide accurate and stable magnetic switching points. In the circuit design, low power consumption Hall element 148 provides a controlled clock mechanism to provide a clock source for the Hall element and analog signal processing circuit, but this can be controlled by the clock mechanism control signals current-consuming circuit periodically enter a "sleep" mode; by this mechanism, the chip is periodically "wakes up" and the size of the Hall element pass through the magnetic field strength of the magnetic field strength in accordance with a predetermined threshold detector good outside. If the flux density is higher than the "operating point" threshold or below the "release point" threshold, the open drain output transistor is driven and latched into the Correspondingly state. In the "sleep" cycle, the output transistor is locked in its previous state. In battery-powered applications, this design to extend the working life to provide the best support. Second, the 148 Hall switching characteristics: · 2.4V - 5.5V battery application of magnetic switching points and high sensitivity stability · immunity to mechanical stress · digital output signal which is non-polar switch permits environmental unleaded III of the report, after sales We are specialized in providing a Hall effect element, a Hall IC companies. Company to better work attitude attention to every detail of the product, in order to improve the quality system standards and strict scientific management system to bring you quality assurance, the principle of good faith to provide quality Hall-effect element for the domestic electronics manufacturers rows, won the praise of customers and related industries.
