Product details
Overview
BQ24163RGET from Texas Instruments is a 2.5-A dual-input switched-mode Li-ion battery charger with power path management and I²C interface, designed for portable systems requiring simultaneous system power and battery charging. It supports USB (up to 1.5 A at 6.5 V) and IN (up to 2.5 A at 10.5 V) inputs, delivers ±1% battery voltage regulation accuracy, and enables instant system startup from zero-battery or deeply discharged conditions in handheld and portable media devices.
For engineers reviewing the BQ24163RGET datasheet, BQ24163RGET pinout, BQ24163RGET application, or BQ24163RGET equivalent, key selection considerations include its JEITA-compatible NTC monitoring, programmable input current limits via I²C, VMINSYS = 3.2 V minimum system regulation, and VBATSHRT = 2.0 V battery short-circuit detection threshold - all critical for robust portable power design.
Technical Context
The BQ24163RGET implements a synchronous buck converter with integrated high- and low-side MOSFETs (RON ≤ 110 mΩ top, ≤ 115 mΩ bottom), enabling up to 2.5-A charge current and 3-A system output. Its power path architecture decouples SYS from BAT, allowing independent control of system power delivery and battery charging through dedicated PMIDI/PMIDU rails and dynamic voltage regulation.
It features dual-input isolation with automatic source selection via I²C, D+/D– USB detection logic, and JEITA-compliant thermal monitoring using the TS pin with four programmable thresholds (VHOT, VWARM, VCOOL, VCOLD). Safety functions include input OVP (6.5 V USB / 10.5 V IN), battery OVP (1.05×VBATREG), thermal shutdown (165 °C), and cycle-by-cycle current limiting (4.9 A typical).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Charge Current | Programmable up to 2.5 A - supports fast charging of high-capacity single-cell Li-ion batteries in space-constrained portable devices. |
| Battery Regulation Accuracy | ±1% - ensures precise termination and longevity for Li-ion cells across temperature and aging. |
| Input Voltage Ranges | USB: 4.2–6 V; IN: 4.2–10.5 V - enables flexible sourcing from USB ports or AC adapters without external LDOs or regulators. |
| VMINSYS Threshold | 3.2 V - maintains stable system operation during deep battery discharge by sustaining SYS rail before battery recovery. |
| VBATSHRT Detection | 2.0 V with 100 mV hysteresis - triggers safe battery short-circuit protection before damaging currents flow into defective cells. |
| Oscillator Frequency | 1.5 MHz typical - allows use of compact 1–2.2 µH inductors and reduces EMI compared to lower-frequency chargers. |

| SCL/SDA | I²C interface | Configures charge voltage/current, input limits, safety timers, and reads status registers; pull-ups required externally. |
| STAT/INT | Status outputs | Open-drain signals indicating charge state (STAT) and faults (INT); 128 µs pulse on fault for host interrupt handling. |
| PGND | Power ground | Primary return path for high-current switching; must be connected to thermal pad and PCB ground plane for thermal integrity. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-input Li-ion charger applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ24161BRGER | Same package and pinout; uses PSEL-based USB detection instead of D+/D–; supports only standard (non-JEITA) NTC monitoring. | Lacks JEITA thermal profile - unsuitable where multi-zone temperature-aware charging is required (e.g., medical or automotive-adjacent devices). | Select BQ24161BRGER only if USB source type is known in advance and JEITA compliance is not mandated. |
| BQ24160RGET | Identical pinout, package, and JEITA support; differs only in absence of safety timer disable function and slightly higher VMINSYS (3.5 V vs. 3.2 V). | Higher VMINSYS may cause earlier system brownout under heavy load with weak batteries; lacks software-disable option for safety timer. | Choose BQ24160RGET when full safety timer functionality is required and system can tolerate 3.5 V minimum SYS regulation. |
Compared with BQ24161BRGER and BQ24160RGET, the BQ24163RGET uniquely combines D+/D– USB detection, JEITA thermal compliance, and the lowest VMINSYS (3.2 V) - making it optimal for portable devices prioritizing instant-on capability and wide-temperature charging safety.

FAQ
What is the maximum supported charge current for the BQ24163RGET?
The BQ24163RGET supports a programmable fast-charge current up to 2.5 A via I²C register configuration. This value is specified under recommended operating conditions (VIN = 4.2–10.5 V, TJ = 0–125 °C) and assumes proper thermal management using the exposed PGND pad in the VQFN-24 package. The actual delivered current depends on input voltage, battery voltage, and PCB layout thermal performance.
Does the BQ24163RGET support JEITA-compliant battery charging?
Yes, the BQ24163RGET supports JEITA-compliant charging through its TS pin, which monitors an external NTC thermistor and provides four programmable thresholds: VHOT, VWARM, VCOOL, and VCOLD. These thresholds align with JEITA standard temperature zones, enabling dynamic charge current reduction or suspension during extreme hot or cold conditions - confirmed in the device comparison table and electrical characteristics section of the datasheet.
What are the input overvoltage protection (OVP) thresholds for the BQ24163RGET?
The BQ24163RGET has separate OVP thresholds: 6.5 V (±0.2 V) for the USB input and 10.5 V (±0.2 V) for the IN input. These values are absolute maximum ratings validated across temperature and process variation, and the device enters hiccup mode upon OVP detection to protect internal circuitry while maintaining communication via I²C.
How does the power path management in the BQ24163RGET enable instant system startup?
The BQ24163RGET's power path architecture regulates the SYS rail independently of the battery, allowing the system to power on immediately even with a 0-V battery or no battery installed. When input is applied, the DC-DC converter powers SYS directly while simultaneously charging BAT - eliminating boot delays caused by battery pre-charge sequences common in linear chargers.
Which package options are available for the BQ24163RGET?
The BQ24163RGET is offered exclusively in the VQFN-24 (RGE) package: 4.0 mm × 4.0 mm body with 24 terminals and an exposed thermal pad connected to PGND. This package is distinct from the WCSP-49 (YFF) variant used by other members of the BQ2416x family; the RGE variant is optimized for thermal performance and manufacturability in high-volume portable designs.
