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.

GaN Devices for Mobile Base Station Transmitters

Infineon Technologies recently introduced its first devices in a family of Gallium Nitride (GaN) on Silicon Carbide (SiC) RF power transistors. The devices enable mobile base station manufacturers to build smaller, more powerful and more flexible transmitters. With higher efficiency, improved power density, and more bandwidth than currently used RF power transistors, the new devices improve the economics of building infrastructure to support today’s cellular networks. Additionally, they will enable the transition to 5G technology with higher data volumes and enhanced user-experience.Infineon-gan-group

The new RF power transistors leverage the performance of GaN technology to achieve ten percent higher efficiency and five times the power density of the LDMOS transistors commonly used today. This translates to smaller footprints and power requirements for the power amplifiers (PA) of base station transmitters in use today, which operate in either the 1.8-2.2 GHz or 2.3-2.7 GHz frequency range. Future GaN on SiC devices will also support 5G cellular bandsup to the 6 GHz frequency range. This roadmap allows Infineon to build on its long-standing expertise and state-of-the-art production technologies for RF transistor technology.

Design flexibility and support for the next-generation of 4G technology are additional benefits of GaN devices for RF power applications. The new devices have twice the RF bandwidth of LDMOS, so that one PA can support multiple operating frequencies. They also have increased instantaneous bandwidth available for transmitters, which lets a carrier offer higher dates using the data aggregation technique specified for 4.5G cellular networks.

High-Accuracy, 3-D Magnetic Sensor

Infineon Technologies recently announced the availability of the TLV493D-A1B6, a 3-D magnetic sensor that features highly accurate three-dimensional sensing with extremely low power consumption in a small six-pin TSOP package. Magnetic field detection in x, y, and z directions enables the sensor to measure 3-D, linear, and rotation movements. The implemented digital I²C interface enables fast and bidirectional communication between the sensor and microcontroller.3D-Magnetic-Sensor_TSOP6_Infineon

The TLV493D-A1B6 is intended for consumer and industrial applications that require accurate 3-D measurements or angular measurements or low power consumption, such as joysticks, electric meters where the 3-D magnetic sensor helps to protect against tampering, and more. With its contactless position sensing and high temperature stability of magnetic threshold, the TLV493D-A1B6 enables these systems to become smaller, more accurate, and robust.

The 3-D magnetic sensor TLV493D-A1B6 enables smaller and more energy efficient e-meter systems. Today, up to three magnetic sensors—one for each dimension of external magnetic field—are needed to measure tampering attempts with large magnets. In future, the 3-D magnetic sensor TLV493D-A1B6 will replace all 3-D sensors thus making e-meters smaller and more energy efficient.

The 3-D sensor TLV493D-A1B6 detects all three dimensions of a magnetic field. Using lateral hall plates for the z direction and vertical Hall plates for the x and y direction of the magnetic field, the sensor can be used in a large magnetic field range of ±150 mT for all three dimensions. This allows measuring and covering a long magnet movement. The large operation scale also makes the magnet circuit design easy, robust and flexible.

The TLV493D-A1B6 provides 12-bit data resolution for each measurement direction. This allows a high data resolution of 0.098 mT per bit (LSB) so that even the smallest magnet movements can be measured.

One of the main development goals for the TLV493D-A1B6 sensor was low power consumption. In Power Down mode, the sensor only requires 7-nA supply current. To perform magnetic measurements, the sensor can be set in one of five different power modes. In Ultra Low Power Mode, for example, the sensor performs a magnetic measurement every 100 ms (10 Hz) resulting in a current consumption of 10 µA. The time between measurement cycles can be set flexibly allowing system specific solutions. Using the sensor with continuous measurements, the maximum power consumption is only 3.7 mA. Also, the power modes can be changed during operation.

The TLV493D-A1B6 uses a standard I²C digital protocol to communicate with external microcontrollers. It is possible to operate the sensors in a bus mode to eliminate additional wiring cost and efforts.

Targeting industrial and consumer applications, TLV493D-A1B6 can be operated on supply voltages between 2.7 and 3.5 V and in a temperature range from –40°C to 125°C. The product is qualified according to industry standard JESD47.

For a fast design-in process, Infineon offers the “3D Magnetic 2Go” evaluation board. In combination with the free 3-D sensor software, first magnetic measurements are attainable within minutes. The evaluation board applies the Infineon 32-bit XMC1100 micrcontroller that uses the ARM Cortex-M0 processor.

The “3D Magnetic 2Go” is currently available (www.ehitex.com). Engineering samples of the TLV493D-A1B6 designed for consumer and industrial applications will be available as of July 2015. Volume production is expected to start in January 2016.
