Product details
Overview
O919A152TRGZRQ1 from Texas Instruments is an automotive-grade power management unit (PMU) integrating four step-down SMPS regulators (two 3.5-A, one 3-A, one 1.5-A), four LDOs (300-mA, 300-mA, 100-mA, 200-mA), a 12-bit sigma-delta GPADC with 8 channels, thermal monitoring, and configurable power sequencing - designed for processor core, memory, and I/O rail supply in automotive ADAS and digital cluster systems.
For engineers reviewing the O919A152TRGZRQ1 datasheet, O919A152TRGZRQ1 pinout, O919A152TRGZRQ1 application, or O919A152TRGZRQ1 equivalent, this page delivers verified technical context, validated pin functions, real-world automotive use cases, and confirmed alternative options aligned to AEC-Q100 Grade 2 (–40°C to +105°C ambient) requirements.
Technical Context
The O919A152TRGZRQ1 implements OTP-programmed power sequencing for startup, sleep/active transitions, and fault recovery, with hardware- and software-controlled Eco-mode across SMPS regulators. Its dual-phase capability on SMPS1/SMPS2 enables 7-A combined output with differential remote sensing and dynamic voltage scaling (DVS) support via dedicated I²C and SPI interfaces.
Integrated thermal shutdown, short-circuit protection per SMPS/LDO, and GPADC-based system health monitoring (die temperature, supply voltage, output current) feed into an interrupt handler that notifies the host processor. The 32-kHz RC oscillator and SYNCCLKOUT allow synchronization of multiple PMUs to reduce system-level EMI.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Operating Temp Range | AEC-Q100 Grade 2: –40°C to +105°C ambient - qualified for under-hood and instrument panel mounting in automotive ECUs. |
| SMPS Output Current | Two 3.5-A SMPS (configurable as dual-phase 7-A), one 3-A, one 1.5-A - supports high-current processor cores and memory rails. |
| LDO Output Current | Two 300-mA LDOs (bypass-capable), one 100-mA low-noise LDO (≤50 mA noise-critical), one 200-mA LDO - powers I/O, RTC, analog sensors, and low-power domains. |
| ADC Resolution & Channels | 12-bit sigma-delta GPADC with 8 total inputs (2 external, 6 internal) - enables real-time monitoring of VCC_SENSE, die temperature, and SMPS output currents. |
| Control Interfaces | SPI + two I²C ports (one dedicated to DVS, one general-purpose) - allows simultaneous configuration, voltage scaling, and telemetry without bus contention. |
| Power Sequencing | OTP-configurable power-up/down and SLEEP↔ACTIVE sequences - eliminates boot firmware dependency for safe, repeatable system initialization. |
| Quiescent Current | 20 μA in Off mode, 90 μA in Sleep mode (with two SMPS active) - extends battery life during vehicle key-off states. |
Pinout & Package
Package: 7-mm × 7-mm VQFN-48 (RGZ) with exposed thermal pad - optimized for automotive thermal dissipation and PCB area efficiency in space-constrained modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| SMPS1_IN / SMPS2_IN / SMPS3_IN / SMPS4_IN | SMPS input supply pins | Accept 3.135–5.25 V system input; each feeds its respective buck regulator stage with independent overvoltage protection. |
| SMPS1_FDBK / SMPS2_FDBK | Dual-phase feedback inputs | Enable differential remote sensing for SMPS1/SMPS2 in dual-phase mode - improves load regulation accuracy under high-current transient conditions. |
| GPIO_3 | Multi-function I/O | Configurable as SYNCDCDC input to synchronize switching frequency across multiple O919A152TRGZRQ1 devices - reduces beat-frequency EMI in multi-PMU systems. |
| INT | Interrupt output | Open-drain signal asserting on thermal warning, short-circuit detection, or GPADC threshold breach - triggers host processor exception handling without polling. |
| BOOT | Boot configuration pin | Tri-level input (ground/VRTC/floating) selecting OTP power-up sequence variant - enables hardware-selectable boot profiles without reprogramming. |
Key Features
| Feature | Design Value |
|---|---|

| OTP power sequencing | Factory-programmed startup/shutdown order with fail-safe bit-integrity checking - prevents undefined system state on corrupted configuration. |
| GPADC with external channels | Monitors two external voltages (e.g., battery, sensor supply) alongside internal rails - eliminates need for external monitoring ICs in compact ADAS designs. |
| Fail-safe GPIO inputs | 5.25-V tolerant GPIO_0/GPIO_1/GPIO_3/GPIO_5 - interfaces directly with 5-V automotive switches and sensors without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65917Q1RSLRQ1 | Three 3-A SMPS, three 300-mA LDOs, no GPADC, no dual-phase mode - lower integration, smaller footprint (6×6 mm). | Lacks ADC-based health monitoring and dual-phase high-current capability - suitable for cost-sensitive entry-level clusters without thermal telemetry. | Select when GPADC and 7-A dual-phase output are not required; offers lower BOM count for simpler systems. |
| MAX20029ATGB/V+T | Four 3-A SMPS, four LDOs, 10-bit SAR ADC (4 ch), AEC-Q100 Grade 2, but no OTP sequencing - relies on host MCU for power control. | Requires external firmware for sequencing and DVS - increases software validation burden and boot time uncertainty. | Choose when design already includes robust MCU-based power management and ADC resolution ≥10 bits suffices. |
Compared with TPS65917Q1RSLRQ1 and MAX20029ATGB/V+T, the O919A152TRGZRQ1 uniquely combines OTP-based autonomous sequencing, dual-phase 7-A capability, and 12-bit GPADC - delivering higher functional safety readiness and reduced host processor dependency in complex ADAS platforms.

FAQ
What is the AEC-Q100 qualification status of the O919A152TRGZRQ1?
The O919A152TRGZRQ1 is fully AEC-Q100 qualified as Grade 2, with device temperature range –40°C to +105°C ambient, HBM Class 2 (±2 kV), and CDM Class C4B (±500 V). This qualification is documented in the official TI production datasheet SLVSDM1A and applies to the exact O919A152TRGZRQ1 device marking and RGZ package.
Does the O919A152TRGZRQ1 support dynamic voltage scaling (DVS) for processor cores?
Yes, the O919A152TRGZRQ1 supports hardware- and software-controlled DVS on its two 3.5-A SMPS regulators (SMPS1 and SMPS2) via dedicated I²C and SPI interfaces. Voltage steps are programmable in 10-mV or 20-mV increments across 0.7–3.3 V, enabling real-time adaptation to CPU load changes without host intervention.
Can the O919A152TRGZRQ1 operate without external firmware configuration?
Yes, the O919A152TRGZRQ1 uses factory-programmed OTP memory to execute full power-up, power-down, and SLEEP↔ACTIVE sequences autonomously. Default voltage settings, GPIO configurations, and startup timing are active immediately after power application - no host firmware is required for basic operation.
What thermal protection features does the O919A152TRGZRQ1 include?
The O919A152TRGZRQ1 integrates high-temperature warning (programmable threshold), thermal shutdown at 150°C junction temperature, and continuous die temperature monitoring via its 12-bit GPADC. Thermal events trigger the INT pin and can be logged through I²C/SPI registers for diagnostic analysis in automotive black-box recorders.
Is the O919A152TRGZRQ1 pin-compatible with other TPS659xx-Q1 family members?
No, the O919A152TRGZRQ1 is not pin-compatible with other TPS659xx-Q1 variants such as TPS65917 or TPS65916. Its 48-pin RGZ layout, GPIO mapping (e.g., GPIO_3 as SYNCDCDC), and SMPS feedback pin assignments (SMPS1_FDBK/SMPS2_FDBK for dual-phase) are unique to this specific device configuration.
