Texas Instruments TPS65010RGZRG4

Overview

TPS65010RGZRG4 from Texas Instruments is a highly integrated power and battery management IC for single-cell Li-Ion/Li-Polymer systems, featuring a linear charger (1-A AC/500-mA USB), dual step-down converters (1-A VMAIN @ 95%, 400-mA VCORE @ 90%), two 200-mA LDOs, I²C interface, thermal shutdown, and programmable power sequencing - deployed in PDAs, smartphones, and digital still cameras.

For engineers reviewing the TPS65010RGZRG4 datasheet, TPS65010RGZRG4 pinout, TPS65010RGZRG4 application, or TPS65010RGZRG4 equivalent, this page delivers verified functional roles, validated pin functions, confirmed operating ranges (e.g., VMAIN: 2.5–3.3 V, VCORE: 0.85–1.6 V), real-world sequencing behavior (PS_SEQ-controlled startup), and accurate alternative part comparisons grounded in TI's official documentation and electrical specifications.

Technical Context

The TPS65010RGZRG4 implements autonomous dual-input (AC/USB) charging with external resistor-programmable current (ISET), precision voltage regulation (±3% LDO accuracy, 1% VREF), and adaptive light-load mode in both 1.25-MHz synchronous buck converters to sustain efficiency across 10 mA–1 A loads. Its I²C interface (100/400 kHz) enables dynamic voltage scaling (DEFCORE/DEFMAIN), LDO enable control, and fault reporting via INT/PWRFAIL.

Power sequencing is managed through PS_SEQ and LOW_PWR inputs, enabling deep-sleep core voltage reduction (to 1.5 V or 1.6 V) and coordinated power-up/down of VMAIN, VCORE, and LDOs. Thermal protection (160°C shutdown), UVLO (2.5 V threshold), and battery cover detection (BATT_COVER) provide system-level safety without external circuitry.

Key Specifications

Pinout & Package

TPS65010RGZRG4 is housed in a 48-pin VQFN package (7.0 mm × 7.0 mm) with exposed thermal pad (connected to PGND). The package supports high-power dissipation (R_θJA = 27.0°C/W) and requires PCB thermal vias under the pad for reliable operation above 1 W.

FAQ

What is the maximum supported charge current for TPS65010RGZRG4 when using an AC adapter?

The TPS65010RGZRG4 supports up to 1 A of charge current from an AC adapter (4.5–5.5 V), set by an external resistor on the ISET pin. The K_SET factor is 310–350 mA/V, allowing precise adjustment across the full 100 mA–1 A range. This is confirmed in Section 6.6 of the SLVS149C datasheet under "IO(AC) Output current range for AC operation".

Does TPS65010RGZRG4 support automatic power-source selection between AC and USB inputs?

Yes, TPS65010RGZRG4 implements hardware-based autonomous source selection: it prioritizes AC over USB over battery without firmware involvement. When both AC and USB are present, the internal logic enables the AC path first. This behavior is documented in the "Features" section and functional description of the SLVS149C datasheet.

Can TPS65010RGZRG4 generate a 1.2-V core voltage for a DSP processor?

Yes, TPS65010RGZRG4 supports 1.2 V VCORE output. Its VCORE converter is programmable in 0.1-V steps from 0.85 V to 1.6 V via I²C registers or DEFCORE pin strapping. At 1.2 V, it delivers up to 400 mA with ±3% accuracy and 0.002%/mA load regulation - verified in Table 6-12 of the SLVS149C datasheet.

How does the LOW_PWR pin affect VCORE regulation in TPS65010RGZRG4?

When LOW_PWR is asserted high, TPS65010RGZRG4 lowers VCORE to a predefined value (1.5 V if DEFCORE = 0, or 1.6 V if DEFCORE = 1) to reduce processor leakage current during deep sleep. This hardware-controlled scaling occurs without I²C interaction and is detailed in Section 7.4 ("Device Functional Modes") of SLVS149C.

Is thermal shutdown implemented in TPS65010RGZRG4, and what is the trip threshold?

Yes, TPS65010RGZRG4 includes integrated thermal shutdown that triggers at 160°C junction temperature (T_SD), with 20°C hysteresis. Upon activation, PWRFAIL goes low within 1.68–3.2 ms before supplies are disabled - a safety feature confirmed in Sections 6.5 and 6.9 of the SLVS149C datasheet.
