company blog about Mingjiada Electronics Acquires Infineon’s OPTIREG™ Power Management ICs to Empower Automotive Applications Such as ADAS, Chassis, and Powertrain

As the automotive industry accelerates its transition toward electrification, intelligent systems, and connectivity, automotive-grade power management ICs have become a core pillar of automotive electronic systems. Shenzhen Mingjiada Electronics Co., Ltd. (hereinafter referred to as “Mingjiada Electronics”) announced a global acquisition of Infineon’s OPTIREG™ series of power management ICs, covering four major product lines: PMICs, SBCs, switching regulators, and linear regulators. This initiative provides inventory liquidation and resource recycling solutions for applications such as Advanced Driver Assistance Systems (ADAS), chassis and safety systems, powertrain, and body control.

Product Types Acquired: Full Coverage of Four OPTIREG™ Sub-Series

The Infineon OPTIREG™ power management ICs acquired by Mingjiada Electronics in this transaction include the following complete product categories:

1. OPTIREG™ PMIC (Power Management Integrated Circuit)

This is the highest-integration product line within the OPTIREG™ family, designed specifically for multi-rail power supply scenarios. Representative models include the TLE35584/5, TLF30682, and TLF9243. Some models (such as the TLF35584/5) meet the ISO 26262 ASIL-D functional safety standard and can provide reliable multi-channel voltage supply for Infineon’s AURIX™ MCUs and other microcontrollers. The PMIC integrates safety mechanisms such as a buck-boost pre-regulator, multiple downstream regulators, window and functional watchdogs, and voltage monitoring, making it suitable for applications with extremely high functional safety requirements, such as domain controllers, radar systems, and gateways.

2. OPTIREG™ SBC (System-on-Chip)

The SBC integrates power management, CAN/LIN communication interfaces, watchdog, and safety monitoring functions within a single chip, serving as a core component for body control modules, ADAS controllers, and infotainment systems. This series complies with the AEC-Q100 automotive standard and supports the latest in-vehicle network protocols such as CAN FD.

3. OPTIREG™ Switcher (Switching Regulator)

This series consists of synchronous buck regulators. Typical models include the TLS4120D0EPV50 (2A) and TLS4125D0EPV33 (2.5A), which support a wide input voltage range of 3.7V to 42V and are suitable for automotive battery startup applications. Features include ±1.5% feedback voltage accuracy, spread-spectrum modulation for enhanced EMI performance, and light-load PFM mode for optimized efficiency. These regulators are widely used in body control, ADAS, infotainment, and navigation systems.

4. OPTIREG™ Linear (Linear Regulators)

For noise-sensitive applications, OPTIREG™ linear regulators provide a “clean” power supply with low noise (<30 µV) and high PSRR, making them suitable for RF front-ends, high-precision sensors, and other scenarios. According to Infineon’s official website, this series includes 17 automotive-grade models, such as the TLS208D1xxVxx, with some supporting output currents of up to 1.5A.

Core Application Scenarios: Four Key Automotive Sectors

The OPTIREG™ series of chips is widely used in the following automotive electronics applications, which are also the primary sources of inventory acquired by Mingjiada Electronics:

ADAS and Autonomous Driving: Domain controllers, millimeter-wave radar, cameras, gateways, PMICs (ASIL-D), SBCs

Chassis and Safety: Electric power steering (EPS), braking, suspension, PMICs, SBCs

Powertrain: Transmissions, main inverters, battery management systems (BMS), PMICs, Switchers

Body and Comfort Systems: Body control modules, infotainment, navigation, lighting, SBCs, Switchers, Linear

OPTIREG™ PMICs are specifically designed for applications such as ADAS (domain controllers, radar, gateways), chassis (EPS, braking, suspension), and powertrain (transmission, main inverter, BMS). New models, such as the TLF35585, extend the junction temperature range to 175°C to meet functional safety requirements in harsh automotive environments.
