BQ25306RTER Description

Short technical summary and product information.

The BQ25306RTER from Texas Instruments is a standalone, high-efficiency, 1.2-MHz synchronous switch-mode buck battery charger designed for 1-cell and 2-cell Li-ion, Li-polymer, and LiFePO4 batteries. It supports a wide input voltage range from 4.1V to 17V, with an absolute maximum rating of 28V, and can deliver a maximum fast charge current of 3A. The device integrates reverse blocking and synchronous switching MOSFETs, internal input and charge current sensing, and loop compensation, contributing to a low Bill of Materials (BOM) cost.

 

Key features include a programmable charge voltage range of 3.4V to 9.0V, ±0.5% charge voltage regulation accuracy, and ±10% charge current regulation accuracy. It boasts a low quiescent current of 200nA at 4.5V V_BAT and 4.25µA VBUS supply current in IC disable mode, maximizing battery energy conservation. Safety features include thermal regulation and shutdown, input UVLO and OVP, battery overcharge protection, and cold/hot battery temperature protection.

 

The BQ25306RTER is available in a compact 16-WQFN (3x3mm) package, suitable for space-limited applications and designed for easy 2-layer PCB layout. Its high integration and efficiency make it ideal for applications such as wireless speakers, gaming devices, cradle chargers, and medical equipment.
