Texas Instruments BQ25710RSNR, Battery Monitor, Multi-Chemistry, SMBus Interface, 1-4 Cells, Fault Protection, -40°C to 85°C, 32-WFQFN Exposed Pad.
| Parameter | Value |
|---|---|
| Mounting type | Surface Mount |
| Interface | SMBus |
| Operating temperature | -40°C~85°C(TA) |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Function | Battery Monitor |
| Case | 32-WFQFN Exposed Pad |
| Number of cells | 1 ~ 4 |
| Fault protection | Over Current, Over Temperature, Over Voltage |

It integrates over-current, over-temperature, and over-voltage fault protection, which reduces external supervisory circuitry on the BOM.
The BQ25710 base product number indicates a family of SMBus battery monitors — the RSNR suffix denotes the 32-QFN package and tape-and-reel or cut-tape shipping format.
Yes, it supports 1 to 4 series cells and is multi-chemistry, so it works with 4S lithium-ion, LiFePO4, and other chemistries the host programs via SMBus.
The evidence does not specify whether external MOSFETs are needed — the part is a battery monitor, not a charger controller with integrated power FETs. Review the datasheet for the external component count in your application.
The BQ25710 and BQ25713 are siblings in the same SMBus battery monitor family. The evidence does not list parametric differences between them — compare the datasheet feature tables for charge current range, ADC resolution, or register map variations that may affect your host firmware.
