3PEAK Launches TPU25401, a Highly Integrated Auto-Grade PMIC Chip! Empowering Efficient and Stable Power Supply for Automotive Cockpits and ADAS


With the rapid development of automotive technology, the electrification and intelligence of automobiles continue to advance, and intelligent cockpits and Advanced Driver Assistance Systems (ADAS) are becoming more prevalent. As a core component in automotive electronic systems, BMS devices directly impact the stability and efficiency of the entire system.

In response to these demands, 3PEAK has released TPU25401, a highly integrated auto-grade Power Management Integrated Circuit (PMIC). It is designed to power the main System-on-Chips (SoCs) in automotive intelligent cockpits, ADAS, and other systems, providing a new choice for power management in automotive electronic systems.TPU25401 adopts innovative technology and a compact design to meet the need for stable, efficient, and flexible power management in automotive intelligent cockpits, ADAS, and other systems. It introduces a breakthrough auto-grade power management solution for automotive electronics.


Typical Application Circuit of TPU25401

Key features of TPU25401 for application in automotive intelligent cockpits and ADAS systems include:

High Performance, High Integration
• Includes 5 buck converters and 5 Low-Dropout Regulators (LDOs), with a total current output capacity exceeding 22 A.
• Output voltage adjusted from 0.6 V to 3.7 V, with a 10 mV adjustment step.
• Non-linear control internally, providing a fast dynamic load response speed, especially suitable for core digital chips such as SoCs.
• 6 × 6 mm 48-pin QFN package.

Flexible Configuration
• Configurable default output voltage and power on/off sequence through One-Time Programmable (OTP) settings.
• Programmable maximum output current capacity.
• Dual-buck channel merging to meet the application requirements of a single high-current channel.
• Master-slave architecture, allowing two PMICs to operate synchronously, providing more power rails with synchronous on/off sequences.

Safe and Reliable

Integrated with multiple protection mechanisms, including current limit protection, short-circuit protection, overload protection, and over-temperature protection. Automatic cut-off output in abnormal situations, protecting the automotive electronic system from damage and ensuring vehicle safety.

The flexible configuration of TPU25401 addresses the limitations of traditional PMICs that can only adapt to a single SoC platform. According to feedback from SoC partners and related Tier 1 feedback, TPU25401 can easily adapt to different SoCs in the automotive market. Taking the intelligent cockpit SoC X9M platform from SemiDrive as an example, only one TPU25401 is needed to meet all the power requirements of the system.
