New Highly integrated Hall sensors

Infineon Technologies recently introduced a new family of Hall sensors targeted at cost-effective, compact designs. Available as latch and switch-type devices, the sensors in the TLx496x family have precise switching points, stable operation, and a low power consumption.Infineon TLx496x

The TLx496x Hall sensors consume no more than 1.6 mA. In addition, they have an integrated Hall element, a voltage regulator (to power the Hall element and the active circuits), choppers (ensure that the temperature remains stable), an oscillator, and an output driver.

 

The TLE496x-xM series is well suited for automotive applications (e.g., power windows and sunroofs, trunk locks, and windshield wipers) with an operating voltage of 3 to 5.5 V. The TLI496x-xM series units function like the TLE496x-xM units, but it is specified for a temperature range of –40° to 125°C and is JESD47 qualified. The TLI496x-xM is used in BLDC motors in e-bikes and fans in PCs and in electric drives in building automation. The TLV496x-xTA/B series was specifically developed for the cost-effective, contactless positioning. Typical applications are BLDC motors in home appliances (e.g., dishwashers), compressors in air-conditioners, and more. Despite the pressure to cut costs, these applications need very precise Hall latches or Hall switches (unipolar/bipolar) for temperatures ranging from –40 °C to 125 °C. The TLV496x-xTA/B versions have a power consumption of 1.6 mA and an ESD protection up to 4 kVH Human Body Model (HBM). The output has overcurrent protection and automatically switches off at high temperatures.

The Hall sensors of all three series are available in high volume. Development support includes online simulation tools and application manuals.
