The first domestically integrated DC-DC motor control dedicated SoC, Jinxin Technology ADM32F036B3Q, has been officially released

As automotive electronic architectures continue to evolve toward 48V systems, higher integration and miniaturization, BLDC motor applications including electronic water pumps, electronic oil pumps, cooling fans, blowers and various actuators impose escalating requirements on control chips. Beyond stronger control performance, these chips are expected to reduce peripheral components, cut system costs, improve overall reliability, and shorten product development cycles.

In response to the core demands of automotive BLDC motor control, Advchip Technology officially unveils the ADM32F036B3Q — China’s first dedicated motor control SoC with integrated DC-DC. Built around a high-performance 32-bit DSP core, the chip integrates on-chip DC-DC, power management, three-phase pre-driver, LIN transceiver and a comprehensive set of control peripherals. It enables a highly integrated motor control platform purpose-built for 48V automotive systems, delivering a simpler, more efficient and reliable solution for automotive thermal management and body electronics applications.

High Integration Redefines 48V Motor Control System Architecture

Traditional 48V motor control solutions mostly rely on a discrete component architecture, where core functions such as power supply, driving and communication are implemented with external peripheral devices. This approach not only results in complex system structure, high material costs and lengthy development and validation cycles, but also introduces hidden risks to long-term product reliability due to the large number of solder joints between components.

The ADM32F036B3Q achieves an architectural upgrade from discrete solutions to single-chip integration, consolidating key functions including power management, three-phase motor pre-driver and LIN communication interface into a single chip. This design significantly reduces the bill of materials, lowers PCB routing complexity and system design barriers. By eliminating excess solder joints between components, it enhances long-term system reliability at the hardware level, helping customers shorten development cycles and accelerate mass production.

High-Performance Motor Control Platform Optimized for 48V Systems

The ADM32F036B3Q is deeply optimized for 48V automotive electrical architectures. Featuring a wide input voltage design, it can be directly adapted to 48V systems of new energy vehicles without additional voltage conversion circuits.

With a built-in complete power supply chain, the chip greatly simplifies system power design. Its integrated high-side drive circuit stably drives power transistors without external bootstrap circuits, further improving driving stability and system reliability. It also integrates an automotive-grade LIN communication interface compatible with mainstream in-vehicle network standards, fully satisfying the communication requirements of next-generation automotive electronics.

In terms of control performance, the chip is equipped with a high-performance 32-bit control core and hardware acceleration units, enabling parallel processing of core computing and control tasks. Coupled with rich peripherals such as high-precision sampling and timing control modules, it supports mainstream motor control algorithms including FOC, sine wave and square wave, readily addressing the control demands of complex automotive motors.

Automotive-Grade Reliability and Comprehensive On-Chip Ecosystem

Beyond core control and driving capabilities, the ADM32F036B3Q integrates mainstream in-vehicle communication interfaces, abundant peripherals, storage resources and security encryption modules, further lowering system development barriers while improving software reuse efficiency and solution scalability.

For reliability, the product meets automotive-grade wide-temperature operating specifications and has obtained AEC-Q100 automotive qualification, supporting long-term stable operation under the harsh environments of automotive electronics. The chip incorporates a full suite of power protection, over-temperature protection and multi-layer fault detection mechanisms, comprehensively boosting system safety and reliability under complex working conditions and providing robust support for automotive motor control applications.

Full-Scenario Adaptation Covering All 48V Automotive BLDC Control Needs

The ADM32F036B3Q is widely compatible with a broad range of 48V automotive BLDC motor control scenarios, delivering the core value of highly integrated solutions across different use cases:

• Electronic water pumps & oil pumps for new energy vehicles: The single-chip solution reduces controller footprint, and its automotive-grade quality meets the demands of long-term in-vehicle operation.

• Air conditioning compressors, cooling fans & blowers: Supports multi-mode speed control, with a LIN interface for seamless integration into the body electronics network.

• Various automotive actuators & valve controls: Rich peripherals accommodate diverse control requirements, and high integration effectively reduces system BOM cost.

• Other 48V BLDC motor drive systems

The launch of the ADM32F036B3Q elevates the integration level of automotive BLDC motor control systems to a new benchmark, providing a more efficient and reliable domestic chip solution for thermal management systems and body electronics of new energy vehicles. Going forward, Advchip Technology will continue to focus on core automotive electronics application scenarios, rolling out more high-performance, high-reliability automotive-grade chip products to support the continuous upgrading of automotive electronic systems.
