Product details
Overview
DA9132-XXRT1-A 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 across a 2.8 V–5.5 V input range. It features remote sensing, I²C-compatible FM+ interface, dynamic voltage control (DVC), and integrated over-temperature/over-current protection - deployed in vehicle infotainment, ADAS, and SIPP modules for SoC/DDR power delivery.
For engineers reviewing the DA9132-XXRT1-A datasheet, DA9132-XXRT1-A pinout, DA9132-XXRT1-A application, or DA9132-XXRT1-A equivalent, key selection considerations include its AEC-Q100 Grade 2 qualification, ±1% static output voltage accuracy, 4 MHz switching frequency, 24-pin FCQFN wettable-flank package (3.3 mm × 4.8 mm), and dual-buck architecture with independent feedback paths for CPU/GPU and DDR rails.
Technical Context
The DA9132-XXRT1-A implements two independent single-phase buck regulators with integrated high-side and low-side MOSFETs, supporting programmable soft-start, cycle-by-cycle current limiting, and thermal shutdown. Its I²C FM+ interface (up to 1 MHz) enables register-level DVC, fault reporting, and GPIO configuration.
Remote sensing on both FB1P/FB1N and FB2P/FB2N pairs ensures ±1% output regulation accuracy under PCB trace resistance variations. The device operates from −40 °C to +105 °C ambient and meets AEC-Q100 Grade 2 requirements for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 2.8 V to 5.5 V - supports direct connection to automotive 3.3 V or 5 V bias rails without pre-regulation. |
| Output Voltage Range (per channel) | 0.3 V to 1.9 V - covers core logic (e.g., 0.8 V CPU), GPU (1.1 V), and DDR I/O (1.8 V) rails. |
| Max Output Current (per channel) | 3 A - sufficient for high-performance automotive SoCs and DDR memory subsystems. |
| Switching Frequency | 4 MHz nominal - enables use of ultra-small 220 nH inductors and compact 20 µF ceramic output capacitors. |
| Output Voltage Accuracy | ±1 % (static), ±5 % (load transient) - ensures stable operation during processor load steps without external compensation. |
| Operating Temperature | −40 °C to +105 °C ambient - qualified per AEC-Q100 Grade 2 for under-hood and cabin electronics. |
| I²C Interface | FM+ compatible (1 MHz max) - supports fast register access for DVC, fault logging, and GPIO reconfiguration. |
Pinout & Package
DA9132-XXRT1-A uses a 24-pin FCQFN package with wettable flanks (3.3 mm × 4.8 mm, 0.5 mm pitch), optimized for automotive thermal and solder-joint reliability. Exposed thermal pad connects to PGND for enhanced heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| PVDD1 (pins 1,2) | Power supply input for Channel 1 | Provides primary bias for Buck1 high-side FET and gate driver; requires local 1 µF decoupling. |
| SCL/GPIO3 (pin 3) | I²C clock / configurable GPIO | Open-drain I²C clock line; can be repurposed as general-purpose input with pull-up. |
| FB1N / FB1P (pins 4,5) | Differential remote sense inputs for Buck1 | Enables Kelvin sensing at load point to reject PCB IR drop; improves regulation accuracy to ±1%. |
| SDA/GPIO4 (pin 6) | I²C data / configurable GPIO | Open-drain I²C bidirectional data line; supports multi-drop bus with configurable address via CONF pin. |
| IC_EN (pin 7) | Global enable input | Active-high logic signal enabling/disabling both buck channels and internal circuitry. |
| CONF/GPIO0 (pin 10) | I²C address configuration / GPIO | Hardwired high/low to select one of four I²C slave addresses (0x48–0x4B) for multi-PMIC systems. |
| FB2P / FB2N (pins 12,13) | Differential remote sense inputs for Buck2 | Independent Kelvin path for Buck2 output; allows simultaneous precision regulation of two distinct rails. |
| LX1 (pins 23,24) | Buck1 power switch node | Connects to external 220 nH inductor; requires tight layout to minimize EMI and switching losses. |
| LX2 (pins 17,18) | Buck2 power switch node | Separate high-frequency switching node for second buck; isolated routing prevents cross-coupling. |
| PGND (pins 19–22) | Power ground return | Low-impedance thermal and current return path shared by both bucks; must connect directly to exposed thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent buck regulators | Two fully integrated 3 A channels with separate feedback, enable, and DVC control - eliminates need for discrete DC-DC controllers and external FETs. |
| Dynamic Voltage Control (DVC) | Real-time output voltage adjustment via I²C write or dedicated GPIO - reduces SoC power consumption during idle/low-load states. |
| Remote differential sensing (FBxP/FBxN) | Compensates for PCB trace resistance up to 50 mΩ - maintains ±1% regulation accuracy without layout constraints. |
| Programmable soft-start | Configurable ramp time limits inrush current during power-up - prevents input rail collapse and avoids false brown-out detection. |
| AEC-Q100 Grade 2 qualification | Validated for −40 °C to +105 °C operation with extended reliability testing - suitable for front-end ADAS and infotainment ECUs. |

FAQ
What is the maximum supported I²C clock frequency for the DA9132-XXRT1-A?
The DA9132-XXRT1-A supports Fast Mode Plus (FM+) I²C operation up to 1 MHz, enabling rapid register reads/writes for dynamic voltage control, fault status polling, and GPIO reconfiguration. This capability is confirmed in Section 3.8 (Digital I/O Characteristics) and Section 5.4.1 (I²C Protocol) of the R16DS0579EJ0300 datasheet. The DA9132-XXRT1-A maintains full timing compliance across its −40 °C to +105 °C operating range.
Does the DA9132-XXRT1-A require external MOSFETs or Schottky diodes?
No, the DA9132-XXRT1-A integrates fully synchronous high-side and low-side power MOSFETs for both buck channels, eliminating the need for external FETs or catch diodes. This integration is explicitly stated on page 1 of the datasheet and verified in the "Benefits" section (page 2), which notes "Fully integrated switching FET's means no external FETs or Schottky diodes are required." The DA9132-XXRT1-A achieves this with internal gate drivers and thermal protection circuitry.
How does remote sensing work on the DA9132-XXRT1-A, and which pins implement it?
Remote sensing on the DA9132-XXRT1-A uses differential feedback pairs - FB1P/FB1N for Channel 1 and FB2P/FB2N for Channel 2 - to measure output voltage directly at the load, rejecting voltage drop across PCB traces. This is detailed in Figure 1 (Simplified Schematic) and Section 5.1.6 (Resistive Divider) of the datasheet. The DA9132-XXRT1-A guarantees ±1% static output accuracy even with up to 50 mΩ trace resistance, making it suitable for long-distance power delivery in automotive ECUs.
What is the purpose of the CONF/GPIO0 pin on the DA9132-XXRT1-A?
The CONF/GPIO0 pin on the DA9132-XXRT1-A configures the device's I²C slave address during power-up, selecting among four possible addresses (0x48–0x4B) to support multiple DA9132-XXRT1-A instances on the same bus. This function is documented in Table 16 (GPIO Pin Assignment) and Section 2.2 (Pin Descriptions). When not used for address configuration, CONF/GPIO0 operates as a general-purpose input/output, adding flexibility in system-level control logic for the DA9132-XXRT1-A.
Is the DA9132-XXRT1-A qualified for automotive use, and what grade does it meet?
Yes, the DA9132-XXRT1-A is AEC-Q100 qualified for automotive applications and meets Grade 2 requirements (operating temperature range −40 °C to +105 °C ambient). This qualification is explicitly stated in the "Key Features" section (page 1) and verified in Section 3.4 (Thermal Specifications) and Table 6 (Package Ratings) of the R16DS0579EJ0300 datasheet. The DA9132-XXRT1-A is designed for deployment in infotainment, ADAS, and telematics systems where reliability under harsh environmental conditions is mandatory.
