BQ25606 Description

Short technical summary and product information.

The BQ25606 from Texas Instruments is a highly integrated, synchronous switch-mode buck charger designed for standalone 1-cell Li-Ion/Li-Polymer battery applications. It supports an input voltage range from 3.9V to 13.5V, with an absolute maximum rating of 20V, making it suitable for various power sources including USB.

This charger IC features a maximum charge current of 3A and a battery charge voltage range of 4.2V to 4.4V. It boasts high efficiency, with up to 92% charge efficiency at 2A from a 5V input and 92% boost efficiency at 1A output. The device includes advanced features such as BAT temperature thermistor monitoring, IC thermal regulation, input current limit (IINDPM), input overvoltage protection (OVP), and input voltage regulation (VINDPM) to maximize adapter power.

Designed for flexibility, the BQ25606 integrates USB On-The-Go (OTG) functionality with a boost converter capable of up to 1.2A output. It supports USB SDP, DCP, and non-standard adapter detection. The charger also features narrow VDC (NVDC) power path management, enabling instant-on operation with no battery or deeply discharged batteries, and ideal diode operation in battery supplement mode. The package is a 24-pin VQFN measuring 4mm x 4mm.

Key electrical specifications include ±0.5% charge voltage regulation and ±6% charge current regulation at specific currents. It also offers ±5% input current regulation. The operating temperature range is -40°C to 85°C.
