Product details
Overview
BQ25713RSNR from Texas Instruments is a synchronous I²C-controlled narrow-voltage DC (NVDC) buck-boost battery charge controller for 1s–4s Li-ion/Li-polymer batteries. It delivers ±0.5% charge voltage regulation, supports 3.5–24-V input, enables USB OTG output (3–20.8 V), and integrates system power monitoring compliant with IMVP8/IMVP9 for CPU throttling in portable computing platforms.
For engineers reviewing the BQ25713RSNR datasheet, BQ25713RSNR pinout, BQ25713RSNR application, or BQ25713RSNR equivalent, this page provides verified technical context, validated pin functions, confirmed NVDC power path behavior, real-world PROCHOT implementation details, and two rigorously cross-checked alternative parts for system-level design continuity.
Technical Context
The BQ25713RSNR implements a four-switch buck-boost topology with automatic mode transition among buck, buck-boost, and boost based on real-time VBUS and battery voltage conditions-no host intervention required. Its integrated ADC monitors VBUS, VSYS, IBAT, IADPT, and PSYS with ±2% current and ±4% power accuracy.
It features TI's patented Pass Through Mode (PTM) to bypass conversion losses during high-power adapter operation and Vmin Active Protection (VAP) that pre-charges input capacitors to absorb transient system load spikes-both critical for Intel IMVP9-compliant platforms with 1S–2S battery configurations.

Equivalent & Alternatives
The following parts are listed as comparable options for similar buck-boost battery charge controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BQ25713BRSNR | Pin- and software-compatible variant with identical electrical specs; differs only in factory-programmed default register values (e.g., PROCHOT profile settings) | Same use cases; selected when specific out-of-box PROCHOT behavior or VAP timing is required without firmware initialization | Drop-in replacement if default register configuration matches target platform requirements |
| BQ25710RSNR | I²C interface with SMBus-compatible protocol; lacks VAP mode and has coarser 64-mV OTG voltage resolution vs. 8-mV on BQ25713RSNR | Suitable for cost-sensitive designs where peak-load buffering and fine-grained OTG voltage control are not required | Preferred for simpler USB-C power banks or docking stations without Intel CPU integration |
Compared with BQ25713BRSNR, the BQ25713RSNR offers identical hardware functionality but distinct factory defaults-making it ideal for designs requiring immediate IMVP9-compliant PROCHOT response without register writes.

FAQ
What is the primary function of the BQ25713RSNR in a portable computing system?
The BQ25713RSNR serves as the core NVDC buck-boost battery charge controller and system power manager. It regulates VSYS from diverse inputs (USB-C PD, legacy adapters), charges 1s–4s batteries with ±0.5% voltage accuracy, enables USB OTG power delivery, and generates IMVP8/IMVP9-compliant PROCHOT signals for CPU thermal throttling-all within a single 4 mm × 4 mm WQFN package. Its architecture ensures uninterrupted operation even with zero-battery or sudden load transients.
Does the BQ25713RSNR support USB Power Delivery 3.0 Programmable Power Supply (PPS)?
Yes, the BQ25713RSNR supports USB PD 3.0 PPS through its USB OTG mode. It delivers adjustable VOTG from 3.0 V to 20.8 V with 8-mV resolution and configurable slew rate-meeting the voltage step and ramp requirements defined in the USB PD 3.0 specification. This capability is implemented natively in hardware and does not require host microcontroller intervention for basic PPS compliance.
How does the Vmin Active Protection (VAP) feature work in the BQ25713RSNR?
The VAP feature in the BQ25713RSNR pre-charges the input decoupling capacitors from the battery when no external adapter is present. During system peak power demand-such as CPU turbo burst-the stored capacitor energy supplements instantaneous current draw, preventing VSYS from collapsing below the minimum regulated threshold. This avoids brownout resets and is explicitly designed to meet Intel's recommendations for 1S–2S battery platforms operating under high-SOC transient loads.
What are the key differences between BQ25713RSNR and BQ25713BRSNR?
The BQ25713RSNR and BQ25713BRSNR are pin- and software-compatible with identical electrical specifications, thermal performance, and functional capabilities. Their difference lies solely in factory-programmed default register values-particularly in PROCHOT triggering thresholds, VAP timing parameters, and charge voltage/current defaults. No hardware or layout changes are needed when substituting one for the other; only firmware initialization sequence may require adjustment to match desired out-of-box behavior.
Can the BQ25713RSNR operate without an I²C host controller?
Yes, the BQ25713RSNR can operate autonomously without I²C communication. Critical functions-including input current limiting (via ILIM_HIZ pin), OTG/VAP enable (via OTG/VAP pin), and basic charge configuration-are supported through hardware pins. However, advanced features like PROCHOT profile customization, real-time telemetry readback, dynamic VAP tuning, and fine-grained OTG voltage programming require I²C access. The device powers up in a safe, functional state using internal defaults.
