NXP power management IC TDA21590AUMA1 Buck Switching Regulator IC Positive 1 Output
The TDA21590AUMA1 is a high-performance automotive-grade power management IC (PMIC) developed by NXP Semiconductors, specifically designed for advanced vehicle electronic systems. This highly integrated device combines multiple voltage regulators, power switches, and monitoring circuits to efficiently manage power distribution in modern automotive applications, including infotainment systems, advanced driver-assistance systems (ADAS), and telematics control units. Operating within a wide input voltage range (4.5V to 40V), the TDA21590AUMA1 ensures stable power delivery even under harsh automotive conditions, such as load dumps and cold-crank scenarios. Its AEC-Q100 Grade 1 qualification (-40°C to +125°C) guarantees reliability in extreme environments, while its low quiescent current minimizes battery drain during standby mode, making it ideal for always-on automotive applications.
Key Features and Benefits
The TDA21590AUMA1 excels with its high level of integration, featuring six buck converters, three linear regulators, and multiple load switches, all configurable via an I²C interface for flexible power sequencing and dynamic voltage scaling. The device incorporates advanced fault protection mechanisms, including overvoltage, undervoltage, overcurrent, and thermal shutdown, ensuring robust operation in safety-critical systems. Its synchronous buck converters achieve up to 95% efficiency, reducing power dissipation and improving thermal performance. The PMIC also supports low-noise operation, crucial for sensitive analog and RF circuits in automotive radar and infotainment systems. Additionally, its programmable power-up/down sequencing simplifies system design and enhances reliability during startup and shutdown events.
Applications and Use Cases
This PMIC is widely deployed in next-generation automotive electronics, including digital cockpits, head-up displays (HUDs), and domain controllers, where its ability to manage multiple voltage rails simultaneously is essential. In ADAS applications, it powers radar sensors, vision processors, and LiDAR modules with minimal noise interference. The TDA21590AUMA1 is also used in electric vehicle (EV) battery management systems (BMS) and on-board chargers, where its high input voltage tolerance and efficiency are critical. Its low EMI emissions make it suitable for connected car systems, including 5G telematics and V2X communication modules, ensuring compliance with stringent automotive EMC standards.
