TPS65386x-Q1 Обзор
What is a multirail power supply? A multirail power supply IC, or system basis chip (SBC), provides several regulated rails (e.g., 5V, 3.3V, 1.2V) and often includes monitoring, wake-up, and safety features. In automotive systems, such ICs power the main MCU and its associated analog and digital peripherals, ensuring stable operation under wide temperature and voltage variations. The TPS65386x-Q1 belongs to the power management IC hierarchy: PMIC -> system basis chip -> power supply.
Key features include a Power Good output (PGOOD) for rail monitoring, two configurable wake-up pins (WAKEx) for wake from external sources, integrated rotation-counter wake-up, and a low-power timer-based wake-up. These features enable low-power modes and fast transitions.
The device is designed to meet automotive safety requirements, making it suitable for ECUs, ADAS modules, and body control units. Its integrated protections and monitoring functions reduce external component count while maintaining safety integrity.
Typical applications include automotive engine control, transmission control, battery management, and central gateway modules. The TPS65386x-Q1 is also compatible with new-generation TI MCUs, allowing reference designs with TI's safety-relevant microcontrollers.
When designing with this device, careful attention must be paid to the PCB layout for thermal management, as the PowerPAD package requires proper soldering and copper pour to dissipate heat. The wake-up pins should be connected to appropriate sources to ensure robust wake functionality. For dynamic power management, the PGOOD signal can be used to enable downstream loads, ensuring proper sequencing.

Заметки по проектированию
The 48-pin HTSSOP PowerPAD package requires proper soldering of the exposed pad to a large copper area for heat dissipation. In automotive environments, thermal resistance is critical; ensure adequate via stitching and a minimum of [DATA_NEEDED] square inches of copper. Without proper thermal design, the junction temperature may exceed limits under high load.
Route the power rails with wide traces to minimize voltage drops. Place decoupling capacitors close to the IC pins. The wake-up pins (WAKEx) should be routed with series resistors for ESD protection. Avoid routing high-speed signals near the power supply traces to reduce noise coupling.
Do not exceed the maximum input voltage. Ensure the enable and wake-up pins are correctly connected to avoid unintended wake events. Verify the PGOOD signal timing for proper system sequencing. Miswiring the wake-up pins can cause the device to be stuck in sleep mode or draw unexpected current.
