【Intelligent Driving Chip Era】Halo Microelectronics' PMIC Product Infuses "Core" Momentum into Automotive Camera Modules
December 31, 2025
Preface
Halo Microelectronics Co., Ltd. (Stock Code: 688173, hereinafter referred to as "Halo Microelectronics") is a leading domestic supplier of power management and signal chain chips. Recently, the company’s automotive-grade PMIC product HL8441, tailor-made for automotive camera modules, provides a compact, low-noise, and high-efficiency power solution for MCUs, SerDes, image sensors, and other components within camera modules.
01 Delivers a Compact Power Solution for Camera Modules
HL8441 is an automotive-grade PMIC with multi-output and multi-programmable features, integrating 3 high-frequency Buck DC-DCs and 1 low-noise LDO. Compatible with various MCUs, SerDes, and image sensors, the product boasts rich integrated functions:
- 3 High-Frequency Buck Converters: With a maximum output current of 1500mA and a switching frequency of up to 2.3MHz, it meets the miniaturization requirements of camera modules. Its spread spectrum technology for switching frequency enables EMI performance comparable to that of similar products from European and American manufacturers.
- 1 Low-Noise LDO: As LDO performance directly impacts camera sensor imaging quality, Apple-to-Apple comparative tests with European and American counterparts show that camera modules equipped with HL8441 deliver superior imaging performance in darkroom tests.
- Programmable Current & Voltage Ranges: Each power output channel features programmable overcurrent protection (OCP), overvoltage protection (OVP), and undervoltage protection (UVP). The chip supports camera modules with up to 8Mbps pixel rate, making it suitable for various image sensors.
- Programmable Power-Up/Power-Down Sequencing: The 4 power outputs and I/O interfaces support fully programmable power-up/power-down sequencing to accommodate diverse loads, ensuring reliable system operation.
02 Complies with ASIL B Functional Safety Standard
Designed in full compliance with ASIL B functional safety requirements, HL8441 integrates multiple fault diagnosis and error correction mechanisms for timely fault reporting, meeting the functional safety design needs of automotive-grade systems.
03 Compatible with COB Packaging Process
COB packaging offers cost-effective and compact system-level solutions for automotive camera module manufacturers, while imposing higher requirements on power management chips. HL8441 supports BI testing for COB-processed automotive camera modules, making it perfectly compatible with COB-packaged products.
04 Wide Junction Temperature Range Operation
The automotive-grade HL8441 supports a wide junction temperature range of -40°C to +125°C, ensuring stable operation in extreme environments. It is well-suited for high-stability and high-reliability scenarios such as intelligent driving camera modules.
Conclusion
Halo Microelectronics' HL8441 automotive-grade PMIC is specifically designed for automotive camera modules. Boasting excellent electrical performance, ASIL B functional safety compliance, flexible programmable protection thresholds (OCP/OVP/UVP), and power sequencing, it is compatible with mainstream image sensors and COB packaging. Meeting the high-reliability power requirements of intelligent driving systems, HL8441 has gained strong recognition from domestic and overseas automotive customers. Halo Microelectronics looks forward to bringing more stable and reliable performance experiences to global users.
