Rohm

The range of uses for LiDAR sensors is expanding to include not only autonomous driving, but also applications in the industrial and infrastructure fields. Improvements to LiDAR sensors are producing longer range and higher resolution.

In addition to improving the characteristics of the laser diode, it is necessary to drive the laser diode at higher speeds and power. The ROHM RLD90QZWx series is a line of 905 nm, high-power, narrow emission-width laser diodes.

The REFLD002-1 reference design includes the BD2311NVX-LB gate driver to drive the RLD90QZWx laser diode. The high speed of the BD2311NVX-LB contributes to improved LiDAR sensor range and resolution.

STMicroelectronics

The STEVAL-LLL014V1 evaluation kit features the SPC582B60E1 32-bit automotive-grade microcontroller for controlling the ALED7709 LED driver via an I2C interface. The main board can be configured and controlled via a Mini-USB connection to a PC running the STSW-LLL014GUI software. The kit also includes an LED board with four strings of 10 LEDs. 

Power Integrations

The RDK-919Q is a development board for the INN3949CQ, a member of the InnoSwitch3-AQ family of power conversion ICs. Operating from an input-voltage range of 50 V to 1000 V dc, ideal for use in 800 V bus systems, the board provides an isolated power supply for loads of up to 60 W, at an output voltage of 24 V. Conversion efficiency is 82%. 

The RDK-919Q works in hot conditions: at 85°C, it can provide a continuous 20 W output with an input at 1,000 V dc. 

The board offers all the benefits of secondary-side control with the simplicity of primary-side regulation: it is insensitive to transformer variation, and provides extremely fast transient response which is independent of load timing. The maximum output ripple voltage is 240 mV.

The EV-L99LDLH32GEN board provides a way to connect the L99LDLH32 multi-channel automotive LED driver to an existing system. To connect a lighting load, it is necessary to design a specific adapter board suited to the chosen OLED panel.

Monolithic Power Systems

The Monolithic Power Systems EVQ5850-J-00A evaluation board demonstrates the capabilities of the MPQ5850, a 36 V smart diode controller with reverse protection.

The MPQ5850 diode controller can drive an external N-channel MOSFET to replace a Schottky diode for reverse input protection. The 20 mV ultra-low dropout minimizes power loss and enables a low minimum input voltage, which makes the MPQ5850 well-suited to cold-crank conditions in automotive applications. 

The 4 μA shutdown current also makes the MPQ5850 ideal for battery-powered applications. The ultra-fast transient response meets the requirements of the ISO16750 standard.

The EVQ5850-J-00A board is fully assembled and tested.
