TPS650352-Q1

The TPS650352-Q1 is a highly integrated power management IC designed for automotive applications, offering robust performance and reliability in demanding environments. It features a dual-channel buck converter capable of delivering up to 3A per channel, enabling efficient voltage regulation for sensitive downstream circuits such as microcontrollers, sensors, and communication modules. The device supports input voltages ranging from 4.5V to 28V, making it suitable for both 12V and 24V automotive systems. This PMIC integrates advanced protection mechanisms including over-current, over-voltage, under-voltage lockout, and thermal shutdown, ensuring safe operation under fault conditions. Its high switching frequency (up to 2 MHz) allows for the use of small external components, reducing overall board space and cost while maintaining excellent transient response. Additionally, the TPS650352-Q1 includes an integrated LDO regulator for low-noise supply rails, ideal for powering analog and RF components that require clean power. Designed with AEC-Q100 Grade 1 qualification, the TPS650352-Q1 meets stringent automotive reliability standards, including operation across a wide temperature range from -40°C to +125°C. It supports multiple power modes—active, sleep, and standby—to optimize efficiency and minimize quiescent current during idle states, which is critical for battery-powered or always-on vehicle systems. The device offers configurable output voltages via I²C interface, allowing flexible system design without requiring hardware changes. Built-in diagnostics and fault logging capabilities support system-level monitoring and facilitate rapid troubleshooting. Its compact 3mm × 3mm QFN package enhances thermal performance and simplifies PCB layout, making it ideal for space-constrained applications like ADAS, infotainment, telematics, and body control modules. In summary, the TPS650352-Q1 provides a reliable, efficient, and scalable power solution tailored for modern automotive electronics, combining high integration, robust protection, and advanced power management features in a single chip.
