Product details
Overview
DA9132-XXRT2-AT from Renesas Electronics is a dual-channel automotive-grade PMIC integrating two fully synchronous buck converters, each delivering up to 3 A at 0.3 V–1.9 V output with ±1 % static voltage accuracy and 4 MHz switching frequency. It supports dynamic voltage control (DVC), remote sensing, and I2C-compatible FM+ interface for CPU/GPU/DDR power delivery in ADAS and infotainment systems.
For engineers reviewing the DA9132-XXRT2-AT datasheet, DA9132-XXRT2-AT pinout, DA9132-XXRT2-AT application, or DA9132-XXRT2-AT equivalent, key selection criteria include AEC-Q100 Grade 2 qualification, wettable-flank 24-pin FCQFN package (3.3 mm × 4.8 mm), integrated over-temperature/over-current protection, and programmable soft-start for rail sequencing in safety-critical automotive ECUs.
Technical Context
The DA9132-XXRT2-AT implements two independent single-phase buck regulators with integrated high- and low-side FETs, eliminating external diodes or discrete switches. Each channel uses resistive feedback (FB1P/FB1N, FB2P/FB2N) with remote sensing capability to maintain ±1 % output accuracy under load and PCB trace variations.
Control is executed via an I2C-compatible FM+ interface (up to 1 MHz) supporting register-based DVC, fault monitoring, and GPIO configuration. The device operates across -40 °C to +105 °C ambient and includes cycle-by-cycle current limiting, thermal shutdown, and programmable power-good signaling via the PG pin.

FAQ
What is the maximum supported I2C clock frequency for the DA9132-XXRT2-AT?
The DA9132-XXRT2-AT supports Fast Mode Plus (FM+) I2C operation up to 1 MHz, enabling rapid register access for dynamic voltage control and real-time fault reporting. This speed allows sub-millisecond updates to output voltage settings during processor load transitions, ensuring the DA9132-XXRT2-AT meets stringent timing requirements in automotive ADAS applications.
Does the DA9132-XXRT2-AT support remote sensing on both output channels?
Yes, the DA9132-XXRT2-AT provides dedicated differential feedback pins (FB1P/FB1N and FB2P/FB2N) for each buck channel, enabling true Kelvin remote sensing at the load point. This architecture maintains ±1 % output voltage accuracy despite PCB trace resistance, making the DA9132-XXRT2-AT suitable for long-flex or multi-layer board routing in automotive head units and digital clusters.
What protection features are integrated into the DA9132-XXRT2-AT?
The DA9132-XXRT2-AT integrates cycle-by-cycle over-current protection, thermal shutdown with hysteresis, and input undervoltage lockout. All protections operate autonomously without host intervention and are reported via the I2C interface and nIRQ pin. These safeguards ensure robust operation in harsh automotive environments where the DA9132-XXRT2-AT powers safety-critical vision and compute subsystems.
Can the DA9132-XXRT2-AT be used in non-automotive applications?
While the DA9132-XXRT2-AT is AEC-Q100 Grade 2 qualified and optimized for automotive use, its electrical specifications-including 2.8 V–5.5 V input, 0.3 V–1.9 V output, and 4 MHz switching-are technically applicable to industrial or medical edge devices requiring high-accuracy, low-noise dual-rail power. However, Renesas does not guarantee non-automotive qualification data, so full validation is required before deployment outside automotive contexts.
How is the DA9132-XXRT2-AT's soft-start time configured?
The DA9132-XXRT2-AT's soft-start duration is programmable via register bits in the BUCK_BUCK1_0 and BUCK_BUCK2_0 registers, allowing ramp times from 0.5 ms to 32 ms in discrete steps. This configurability ensures controlled inrush current management during cold-start conditions, preserving input rail stability and enabling seamless integration into power-up sequences defined in the DA9132-XXRT2-AT's system-level firmware.
