A Hall sensor is a type of sensor based on the Hall effect principle, which uses the influence of an external magnetic field on the trajectory of charged particles in a current-carrying medium to measure the magnetic field. Its working principle is that when a current in conductive material is subjected to an external magnetic field, a voltage difference is generated on its two sides. This phenomenon is known as the Hall effect. Based on the different working modes of the Hall effect, Hall sensors can be divided into two types: linear Hall sensors and Hall switch sensors.


SL1603 is a low-power Hall switch sensor specifically designed for space-constrained systems and battery-sensitive systems. It has high sensitivity and accuracy and can detect changes in magnetic fields. When the applied S-pole or N-pole magnetic induction intensity exceeds the operating point Bop, the chip outputs a low level and continues to maintain the low-level state. The chip output becomes high only when the S-pole or N-pole magnetic induction intensity is lower than the release point Bep. This full-pole magnetic response design enables SL1603 to reliably detect and respond to changes in magnetic fields, meeting the requirements of various applications.


SL1603TH is an excellent model in the SL1603 series, adopting a full-pole response design to sense and respond to changes in the applied S-pole or N-pole magnetic induction intensity. It is suitable for a power supply voltage range of 6V and has a low power consumption of only 3.3μA, making it an ideal choice for battery-powered systems. Additionally, it has a scanning frequency of 20Hz, allowing for fast and accurate detection of magnetic field changes. With a standard SOT-23 package, it is easy to install and integrate into various devices.

SL1603TH has a wide range of applications in the consumer electronics field. For example, in products such as smartphones, tablets, and wearable devices, there is often a need to detect changes in the magnetic field for compasses, flip functions, and smart accessory connections. The low power consumption and compact size of SL1603TH make it very suitable for these devices, providing high-performance magnetic induction detection. In the automotive electronics field, SL1603TH can be used in applications such as vehicle stability control systems, parking assist systems, and vehicle navigation systems. By detecting changes in the magnetic field around the vehicle, it can achieve vehicle positioning, navigation, and obstacle detection. Its full-pole response and reliability make SL1603TH an important component in the automotive electronics field.


In addition to SL1603TH, SLKOR has many high-performance and excellent Hall sensor products, such as SLSS341R-3, SLSS39E-9, SL1625SH, SL1613SL, SL1605TL, SL1615SH, SL-106C, etc., all of which can meet the market's demand for low power consumption and high-performance sensors. SLKOR will continue to promote the innovation and development of electronic products.
