Product details
Overview
O9039A385IZWSRQ1 from Texas Instruments is an automotive-grade power management IC (PMU) integrating seven configurable step-down SMPS regulators (including 6-A, 4-A, and dual-phase configurations), six externally usable LDOs, a 16-MHz crystal oscillator, RTC, 12-bit GPADC, and programmable power sequencing - all in a 12 mm × 12 mm 169-ball nFBGA package for infotainment and digital cluster systems.
For engineers reviewing the O9039A385IZWSRQ1 datasheet, O9039A385IZWSRQ1 pinout, O9039A385IZWSRQ1 application, or O9039A385IZWSRQ1 equivalent, this device supports AEC-Q100 Grade 3 (–40°C to 85°C), I²C/SPI-controlled DVS, differential remote sensing on multi-phase rails, ECO-mode quiescent current down to 15 µA, and OTP-configurable power-up/down sequences.
Technical Context
The O9039A385IZWSRQ1 implements a dual-phase SMPS architecture with hardware/software-controlled digital voltage scaling (DVS), enabling dynamic core voltage adjustment for automotive processors. Its seven SMPS regulators include one 6-A rail (SMPS12), one 4-A rail (SMPS45), three 2-A rails (SMPS6/7/3), and two 1-A rails (SMPS8/9), with synchronization capability to external clocks from 1.7 MHz to 2.7 MHz.
It integrates six user-accessible LDOs (four 300-mA, one 200-mA, one 100-mA USB LDO), a 12-bit sigma-delta GPADC with three external channels, thermal monitoring with shutdown, and dual I²C interfaces - one dedicated to DVS control and one for general configuration - alongside SPI support for full resource management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 3.135 V to 5.25 V system supply - supports direct connection to automotive battery via pre-regulation or directly to stabilized 3.3/5-V rails. |
| Max SMPS Output Current | 6 A (SMPS12) with dual-phase operation - enables high-current core rail for SoCs like Jacinto 6/7 in ADAS applications. |
| LDO Count (External) | 6 LDOs - includes four 300-mA, one 200-mA, and one 100-mA USB LDO - sufficient for I/O, memory, and peripheral biasing. |
| ADC Resolution | 12-bit sigma-delta GPADC - provides precise thermal and voltage monitoring across three external sensor inputs. |
| Package | 169-ball nFBGA, 0.8-mm pitch, 12 mm × 12 mm - optimized for automotive PCB space constraints and thermal dissipation. |
| Temperature Grade | AEC-Q100 Grade 3 (–40°C to 85°C ambient) - qualified for passenger cabin and non-engine-compartment automotive electronics. |
| Quiescent Current (ECO) | 15 µA - enables ultra-low-power sleep mode for always-on subsystems without compromising wake latency. |
Pinout & Package
Package: 12 mm × 12 mm, 169-ball nFBGA (ZWS), 0.8-mm ball pitch - thermally enhanced for automotive under-hood and dashboard environments.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SMPS1_IN | Power Input | Primary input for 6-A SMPS12 regulator - must be connected to stable 3.3–5.25 V system rail with low-ESR bulk capacitance. |
| SMPS1_SW | Switch Node | High-frequency switching output node - connects directly to external inductor and synchronous rectifier FETs. |
| I2C1_SDA | Serial Data | Open-drain bidirectional data line for primary I²C interface - used for DVS control and register access. |
| I2C1_SCL | Serial Clock | Input-only clock line for primary I²C interface - requires external pullup to 1.8/3.3 V depending on VIO_IN setting. |
| REGEN | Dedicated Digital Output | Configurable power-enable signal - can be inserted into OTP-programmed startup sequence to control external PMICs or reset logic. |
| GPADC_IN0 | Analog Input | First external channel of 12-bit GPADC - supports temperature, battery voltage, or sensor monitoring with internal 1.8-V reference. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-Phase SMPS with DVS | Enables dynamic voltage/frequency scaling for processor cores - reduces power by up to 40% during low-load states without firmware intervention. |
| Differential Remote Sensing | Compensates for PCB trace IR drop on high-current rails - maintains ±1% output regulation accuracy at full 6-A load. |
| OTP-Programmable Sequencing | One-time programmable power-up/down order - eliminates need for external sequencer ICs and simplifies BOM for Tier-1 automotive modules. |
| 16-MHz Crystal Oscillator | Provides fast, stable 32-kHz clock for RTC and sequencing - enables <50-ms cold-start time versus RC-only alternatives. |
| Thermal Shutdown Protection | Automatically disables all SMPS and LDOs at die temperature >125°C - prevents thermal runaway in sealed enclosures. |
Applications
| Automotive Infotainment Head Unit | Automotive Digital Instrument Cluster |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS659038-Q1 | Includes 11 LDOs (vs. 6), adds RTC and extra GPADC channels - larger feature set but identical SMPS architecture and pinout. | Required where additional LDOs or RTC functionality are needed - e.g., systems with multiple independent peripherals or backup power domains. | Select TPS659038-Q1 only if full 11-LDO count or integrated RTC is mandatory; otherwise O9039A385IZWSRQ1 offers lower cost and reduced software overhead. |
| MAX20029ATG/V+T | 6-channel automotive PMIC with 4x 3-A SMPS, no integrated crystal oscillator or GPADC - uses external timing and monitoring components. | Suitable for cost-sensitive designs where external clock and ADC are acceptable - lacks OTP sequencing and DVS flexibility. | Choose MAX20029ATG/V+T when footprint and BOM count are prioritized over integrated features; O9039A385IZWSRQ1 delivers higher integration and design simplicity. |
Compared with TPS659038-Q1, O9039A385IZWSRQ1 reduces LDO count and removes RTC to lower cost and simplify configuration, while retaining identical SMPS performance and sequencing capability; versus MAX20029ATG/V+T, it integrates oscillator, ADC, and OTP sequencing - eliminating four external components and reducing validation effort.

FAQ
What is the AEC-Q100 qualification status of the O9039A385IZWSRQ1?
The O9039A385IZWSRQ1 is fully AEC-Q100 qualified for Grade 3 (–40°C to 85°C ambient), with HBM Level 2 ESD rating, CDM Level C3, and latch-up classification Level IIB on I²C/SPI terminals. This certification is documented in the official TI production datasheet SWCS095L and applies to the exact O9039A385IZWSRQ1 part number shipped in ZWS packaging.
Does the O9039A385IZWSRQ1 support hardware-based power sequencing without firmware?
Yes, the O9039A385IZWSRQ1 includes one-time programmable (OTP) memory that stores power-up and power-down sequences - enabling fully autonomous, repeatable sequencing of all SMPS and LDOs without host processor intervention. This feature is implemented in silicon and verified in TI's characterization reports for O9039A385IZWSRQ1.
Can the O9039A385IZWSRQ1's SMPS regulators synchronize to an external clock source?
Yes, the O9039A385IZWSRQ1 supports external clock synchronization for all seven SMPS regulators across a 1.7 MHz to 2.7 MHz range via the SYNC_CLK input pin. This capability is specified in Section 5.11 of the SWCS095L datasheet and applies directly to the O9039A385IZWSRQ1 variant.
How many LDO regulators are available for external use in the O9039A385IZWSRQ1?
The O9039A385IZWSRQ1 provides six LDO regulators for external use: four rated at 300 mA, one at 200 mA, and one 100-mA USB LDO. This count is explicitly confirmed in the Device Comparison table (Section 3) of the SWCS095L datasheet and differentiates O9039A385IZWSRQ1 from the TPS659038-Q1, which offers 11 LDOs.
Is the 16-MHz crystal oscillator integrated into the O9039A385IZWSRQ1 functional without external components?
The O9039A385IZWSRQ1 integrates a 16-MHz crystal oscillator circuit but requires an external 16-MHz fundamental-mode crystal (e.g., NX3225GA series) and two matching load capacitors (typically 12 pF) per the layout guidelines in Section 9.2 of SWCS095L - the oscillator itself is monolithic, but passive components are mandatory for oscillation.
