BQ25672RQMR Description

Short technical summary and product information.

The BQ25672RQMR from Texas Instruments is a highly integrated, switch-mode buck charger suitable for 1-4 cell Li-ion and Li-polymer batteries. It offers a maximum charge current of 3A with 10-mA resolution and operates with a wide input voltage range of 3.6V to 24V, with an absolute maximum rating of 30V.

 

This device features Maximum Power Point Tracking (MPPT) for efficient charging from solar panels, utilizing an autonomous sampled open-circuit voltage (VOC) algorithm. It also supports dual-input power mux control for source selection and includes a narrow voltage DC (NVDC) power path management system. The BQ25672RQMR can provide USB On-The-Go (OTG) functionality, delivering a 5V to 12V buck-boost output voltage with up to 2A current.

 

Key electrical specifications include a switching frequency of 750kHz or 1.5MHz, high efficiency up to 96.5%, and integrated safety features like thermal regulation, thermal shutdown, and over-voltage/over-current protection. The charger operates within a temperature range of -40°C to 85°C and is housed in a 29-pin VQFN package measuring 4mm x 4mm, suitable for surface mounting.

 

Applications for the BQ25672RQMR include video doorbells, smart home controls, data concentrators, robotic lawn mowers, vacuum robots, asset tracking devices, mobile POS systems, multiparameter patient monitors, ECG devices, and ultrasound smart probes.
