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.

The RPR-0720-EVK is an evaluation board for the RPR-0720 infrared (IR) proximity sensor module. 

The ROHM RPR-0720 is an integrated IR proximity sensor module which combines an emitter and receiver in a single small package. 

The RPR-0720’s emitter is an IR vertical-cavity surface-emitting laser. The chip’s built-in IR receiver detects the approach of a person or other object by measuring the rate of reflection of IR light emitted by the VCSEL, over a range between 1 mm and 15 mm. The proximity sensing range is controllable by the system designer via its I2C interface.

Compact sensor module provides reliable proximity detection in consumer devices

The ROHM Semiconductor RPR-0720 infrared module can detect the presence of objects at a range of up to 15 mm. An on-chip I2C interface makes the sensor controllable by any microcontroller.

Step-down switching regulator ICs operate over a wide input-voltage range

The ROHM BD9G buck regulators, which feature an integrated MOSFET, have a high fixed switching frequency, so the power-system designer can save space through the use of smaller magnetic components.
