Low cost hall-effect latch with high magnetic sensitivity

Melexis launched a new Hall-effect latch MLX92214 with high magnetic sensitivity that eases magnet selection and relieves constraints on the size of the air gap.

The new Hall-effect latch suggested for applications such as power tools, PCs, servers, and home appliances keeping low-cost as a factor.

The MLX92214 features an integrated chopper-stabilized amplifier that eliminates output offset with low power consumption. The device is designed to operate with a typical operating current of 2.1 mA, and the wide supply voltage of 2.5 - 5.5 V.

MLX92214 offers ESD-withstand capability of 6 kV (HBM) making it reliable for applications such as hand tools. MLX92214 is also less susceptible to mechanical stress.

MLX92214 work at switching speed upto 10 kHz and can sample at high frequencies for precision measurement at fast rotational speeds. To ensure predictable latching characteristics and stability over the full operating temperature range, the values of operating (BOP) and release (BRP) switching points are symmetrical. Two temperature grades are available, specified from -40 Deg C to 125 Deg C and -40 Deg C to 150 Deg C.

Availability: The MLX92214 is in full production and available in a 3-pin Thin Small Outline Transistor (TSOT) surface-mount package suitable for standalone PCB applications.
