With the rapid development of sectors such as autonomous driving, robotics and smart homes, LiDAR (Light Detection and Ranging) and 3D ToF (Time-of-Flight) sensors have become core components for environmental perception in smart devices. Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as ‘Mingjiada Electronics’), a globally renowned authorised independent distributor of electronic components, has been deeply involved in the semiconductor supply chain sector for nearly thirty years. The company is committed to providing global customers with one-stop supply solutions for LiDAR sensor chips, 3D ToF image sensors and supporting components.
I. Company Strengths: Thirty Years of Experience, Global Supply Chain Network
Established in 1996 and headquartered in Shenzhen, Mingjiada Electronics has established branches in Hong Kong, Japan, Russia and Taiwan, building a global supply network for electronic components. The company has obtained ISO 9001 Quality Management System and ISO 14001 Environmental Management System certifications. It has long distributed products from over 500 internationally renowned semiconductor manufacturers, including brands such as Infineon, ST, TI, NXP, Microchip, ADI, Xilinx and Qualcomm, offering a stock of over 2 million part numbers. In the field of lidar and sensors, Mingjiada Electronics focuses on two major technological approaches: direct time-of-flight (dToF) and indirect time-of-flight (iToF), providing customers with end-to-end services ranging from chip selection to bulk delivery.
II. Core Products: visionICs Series dToF Image Sensors – The Core Solution for Solid-State Lidar
The visionICs series of dToF image sensors supplied by Mingjiada Electronics utilise single-photon detection (SPAD) technology and integrate high-pixel detector arrays with 3D imaging circuits. Capable of outputting 3D point cloud data with centimetre-level accuracy without the need for an external image signal processor, they represent the core sensing solution for solid-state LiDAR. The three main models in this series cover low, medium and high resolution requirements:
1. VI4310 – Highly integrated 3D single-photon imaging sensor
The VI4310 is a system-on-chip (SoC) featuring a 160×120-pixel (19K) SPAD array, with a sensing area of 3,900×3,000 µm², and supports a programmable frame rate of 30 frames per second. It offers a ranging distance of up to 15 metres, a resolution of 0.75 centimetres, and accuracy within ±1 per cent. In terms of interfaces, it supports I²C configuration and DVP output, utilises a multi-voltage power supply of 1.5 V/3.3 V/28.5 V and is housed in a CoB package, with an operating temperature range of –20 °C to 65 °C. This chip is suitable for applications such as ADAS (Advanced Driver Assistance Systems), 3D mapping for robotic vacuum cleaners, security surveillance and AR/VR devices.
2. VI4320 – Precision Single-Photon Time-of-Flight Sensor
The VI4320 features a 64×256-pixel (16K) SPAD array layout with a uniform pixel pitch of 21.44 micrometres and supports a 4×2 pixel binning mode to enhance imaging performance. Its ranging parameters are identical to those of the VI4310 (15-metre ranging range, 0.75-centimetre resolution and ±1 per cent accuracy), and it is fully compatible in terms of interfaces and power supply specifications. This model is particularly well-suited to applications requiring a narrow, elongated field of view, such as autonomous driving LiDAR systems, drone collision avoidance and gesture-controlled interfaces.
3. VI4330 – 76.8K-pixel Advanced Single-Photon Imaging Sensor
As a high-resolution model in the series, the VI4330 features a 320×240-pixel (76.8K) SPAD array with a 15×15-micrometre pixel pitch, supporting 2×2 and 4×4 pixel binning modes. The interface configuration has been upgraded to I²C plus dual MIPI-CSI2/DVP outputs, making it suitable for a wider range of transmission scenarios. This chip is ideal for applications requiring high resolution, such as advanced driver-assistance systems (ADAS), industrial 3D machine vision and high-precision mapping for intelligent robots.
III. Flagship Product: Sony IMX459 SPAD LiDAR Sensor – Automotive-Grade Long-Range Detection
Mingjiada Electronics now offers brand-new, genuine Sony IMX459 SPAD LiDAR sensor chips. This chip is the industry’s first stacked dToF single-photon avalanche diode (SPAD) depth sensor. It utilises Sony’s back-illuminated pixel structure and Cu-Cu hybrid bonding technology to achieve a pixel size of just 10 μm and approximately 100,000 effective pixels, with a detection range of up to 300 metres. The IMX459 utilises a MIPI CSI-2 interface, supports 4/2-channel transmission, and operates within a temperature range of –40°C to 125°C (automotive grade), making it a core sensing component for automotive LiDAR, autonomous driving and Advanced Driver Assistance Systems (ADAS).
Mingjiada Electronics maintains a constant stock of IMX459 chips in its bonded warehouses in Hong Kong and Shenzhen, with an availability rate of 95 per cent. Compared to Sony’s original 20-week lead time, Mingjiada’s lead time for stock items has been reduced to 4–6 weeks; urgent orders can be dispatched within one week, and bulk purchase prices are 15–20 per cent lower than market rates. All products are 100 per cent genuine Sony originals, accompanied by original COC certificates, AEC-Q100 test reports and batch traceability.
Furthermore, Mingjiada offers complete LiDAR solution kits, including 905nm/940nm VCSEL lasers (Lumentum/II-VI), Infineon IRS9102C driver ICs (12A peak current, 250MHz modulation), 905nm AR-coated lenses and narrowband filters, among other supporting components, to simplify customers’ BOM management.
IV. Application Scenarios: From Autonomous Driving to Service Robots
The LiDAR sensor chips and 3D ToF image sensors supplied by Mingjiada Electronics are already widely used in several cutting-edge fields:
Autonomous Driving and ADAS: Automotive-grade SPAD chips such as the IMX459 provide long-range detection capabilities of up to 300 metres for Level 3 and above autonomous driving, serving as the core sensing components in automotive LiDAR systems.
Service Robots: LiDAR modules equipped with VI series chips provide 360° omnidirectional perception and centimetre-level ranging accuracy for cleaning robots, delivery robots and inspection robots.
Industrial 3D Machine Vision: The high-resolution VI4330 chip provides precise depth data for industrial automation and high-precision mapping.
Drones and AR/VR: The VI4320’s narrow, elongated field of view is suited to applications such as drone collision avoidance and gesture control.
