Product details
Overview
TPS65919-Q1 from Texas Instruments is an AEC-Q100 Grade 2 automotive 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 - used to power processor cores, memory, and I/O in digital clusters.
For engineers reviewing the TPS65919-Q1 datasheet, TPS65919-Q1 pinout, TPS65919-Q1 application, or TPS65919-Q1 equivalent, key selection considerations include dual-phase SMPS capability (7-A combined), OTP-programmed power-up/down sequences, differential remote sensing on SMPS1/2, dynamic voltage scaling support via SPI/I²C, and automotive-grade thermal shutdown at 150°C junction temperature.
Technical Context
The TPS65919-Q1 implements a hierarchical power architecture: four independent buck converters with internal 2.2-MHz oscillator or external synchronization (1.7–2.7 MHz), two of which support dual-phase interleaving for reduced ripple and higher current delivery. Each SMPS includes hardware/software Eco-mode, soft-start, short-circuit protection, and power-good indication.
Power sequencing is controlled by factory-programmed OTP memory enabling boot-time operation without host firmware; static configurations (voltage levels, GPIO states) are modifiable via SPI or dual I²C interfaces - one dedicated to DVS control, the other general-purpose. The integrated GPADC monitors die temperature, supply voltages, and external analog signals with 12-bit resolution and automatic threshold detection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PMU applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS65917-Q1 | Three SMPS (2.5-A, 2.5-A, 1.5-A), three LDOs, no GPADC, no dual-phase support | Lacks ADC and dual-phase capability; lower integration for cost-sensitive entry-tier clusters | Select when GPADC and 7-A dual-phase output are unnecessary; footprint-compatible but reduced feature set |
| MAX20029ATG/V+T | Three SMPS (3-A, 3-A, 2-A), five LDOs, 10-bit ADC, no OTP sequencing, SPI-only interface | Higher LDO count but no factory-programmed sequencing; requires host firmware for power-up coordination | Choose when flexible post-boot reconfiguration outweighs deterministic OTP boot; different pinout and register map |
Compared with TPS65919-Q1, TPS65917-Q1 offers lower integration and no dual-phase or ADC capability, while MAX20029ATG/V+T provides more LDOs but lacks OTP sequencing and requires full host control - making TPS65919-Q1 optimal for systems needing autonomous boot, high-current dual-phase rails, and embedded health monitoring.

FAQ
What is the maximum combined output current supported by the TPS65919-Q1 SMPS regulators?
The TPS65919-Q1 supports up to 7-A combined output current by operating SMPS1 and SMPS2 in dual-phase interleaved configuration. This is achieved through synchronized switching with differential remote sensing, enabling higher current delivery with lower ripple and improved thermal performance compared to standalone operation.
Does the TPS65919-Q1 require external firmware to initiate power-up sequencing?
No, the TPS65919-Q1 does not require external firmware to initiate power-up sequencing. Its one-time programmable (OTP) memory contains factory-configured startup and shutdown sequences, allowing fully autonomous boot. Host firmware may optionally modify settings via SPI or I²C after power-on.
How many analog input channels does the GPADC in the TPS65919-Q1 support?
The TPS65919-Q1 integrates a 12-bit sigma-delta general-purpose ADC (GPADC) with eight total input channels: six internal (supply voltages, output currents, die temperature) and two external (ADCIN1 and ADCIN2), each supporting 0–1.25 V input range with programmable thresholds.
What package type and dimensions does the TPS65919-Q1 use?
The TPS65919-Q1 uses a VQFN-48 package measuring 7.00 mm × 7.00 mm with 0.5-mm pitch and an exposed thermal pad (PGND) for enhanced thermal dissipation. This RoHS-compliant, lead-free package is optimized for automotive PCB layouts requiring high power density and thermal reliability.
Can the TPS65919-Q1 synchronize its SMPS switching frequency to an external clock source?
Yes, the TPS65919-Q1 can synchronize its SMPS switching frequency to an external clock applied to the GPIO_3 (SYNCDCDC) pin. The supported external clock range is 1.7 MHz to 2.7 MHz, enabling system-level EMC optimization by aligning multiple PMUs to a common timing reference.
