IR color sensor enhances automotive displays

3 weeks ago | edn.com | Susan Nordyk

Vishay’s VEML6046X00 RGB IR sensor is AEC-Q100 qualified for use in vehicle displays and interior lighting. This compact device integrates a photodiode, low-noise amplifier, and 16-bit ADC in an opaque surface-mount package that is just 2.67×2.45×0.6 mm. With three color channels and one infrared channel, the VEML6046X00 calculates color temperature to enable white point balancing for displays.
Fractal Unveils Acoustic Tech to Disable Drones

3 weeks ago | edn.com | Susan Nordyk

Fractal Antenna Systems has introduced Acoustic Resonance Mitigation (ARM), a technology that disables drones using directed acoustic energy. ARM emits sonic, ultrasonic, and subsonic waves to induce vibrations or Prandtl boundary layer instability, leading to flight failure. Propeller blades are especially vulnerable, as turbulence or vibrations can disrupt a drone’s inertial measurement unit (IMU).

Keysight and Coherent showcased 200G-per-lane VCSEL technology at OFC 2025, demonstrating characterization, tuning, and validation. The multimode VCSEL enables higher data transfer rates to meet growing data center bandwidth demands. Keysight’s M8199B 256-Gsample/s AWGThe 200G multimode VCSEL enhances data transfer and network efficiency by doubling data throughput to 200 Gbps per lane, surpassing current multimode interconnects.
Intelligent high-side switches manage diverse loads

3 weeks ago | edn.com | Susan Nordyk

ST’s four-channel high-side switches, the IPS4140HQ and IPS4140HQ-1, drive resistive, capacitive, and inductive loads with one side connected to ground. The IPS4140HQ handles up to 0.6 A per channel, while the IPS4140HQ-1 supports up to 1.0 A. Both have a maximum RDS(on) of 80 mΩ per channel and include extensive diagnostic and protection features.
Infineon prepares DTO247-packaged IGBTs

3 weeks ago | edn.com | Susan Nordyk

Infineon is developing TRENCHSTOP H7 IGBTs in a DTO247 package, which is twice the size of a standard TO247. A single high-current IGBT in a DTO247 can replace multiple lower-current TO247 IGBTs connected in parallel. Engineering samples of the 200-A and 350-A H7 IGBT variants are available now. The DTO247 enables high power density and bridges the gap between TO247-based designs and module architectures.
Test receivers boost EMI range and compliance

4 weeks ago | edn.com | Susan Nordyk

R&S has expanded its EPL series of test receivers to cover EMI measurements from 5 kHz to 7.125 GHz, offering flexible configuration options. Depending on the setup, these receivers can be used in development, certification preparation, and final testing to ensure compliance with EMI standards. Alongside the previously launched EPL1000, which covers 5 kHz to 30 MHz, the new EPL1001 and EPL1007 operate up to 1 GHz and 7.125 GHz, respectively.
BLE SoC meets automotive requirements

The Renesas DA14533 Bluetooth LE SoC offers power management features to reduce power consumption in automotive systems. AEC-Q100 Grade 2 qualified, it operates from -40°C to +105°C and is suitable for applications such as tire pressure monitoring, keyless entry, wireless sensors, and battery management systems.
Reference design drives servo motors

4 weeks ago | edn.com | Susan Nordyk

ST’s EVLSERVO1, a turnkey reference platform for servo motor control, enables sensorless or sensored field-oriented control (FOC) with one, two, or three shunts. It drives three-phase brushless motors up to 2 kW with the provided heatsink or 3 kW with an external fan. The reference design features the STSPIN32G4 three-phase motor controller with an embedded STM32G4 MCU, enabling advanced position and torque control algorithms, as well as six-step control modes.
Hall elements detect small magnetic fields

4 weeks ago | edn.com | Susan Nordyk

High-sensitivity InSb Hall elements from Diodes detect rotation speed and current across a broad range of applications, even in weak magnetic fields. The AHE300 sensor supports Hall output voltage (VH) classifications C through G, ranging from 168 mV to 370 mV. The AHE10x sensors support VH classifications C through H, with output voltages from 168 mV to 415 mV. These Hall elements are well-suited for mobile phone and laptop opening detection, joystick control, and magnetic encoding.
