BQ24192IRGET Description

Short technical summary and product information.

The BQ24192IRGET from Texas Instruments is a highly integrated, I2C-controlled buck battery charger IC. It is designed for single-cell Lithium-Ion or Lithium-Polymer battery applications, supporting a maximum charge current of 4.5A. The device operates with an input voltage range from 3.9V to 17V, with an absolute maximum rating of 22V.

 

This charger features Narrow Voltage DC (NVDC) Power Path Management, enabling instant-on operation even with no battery or a deeply discharged battery. It includes features like battery temperature monitoring, input current limit (IINDPM), input over-voltage protection (OVP), and USB OTG functionality. The operating temperature range is -40°C to 85°C.

 

The BQ24192IRGET is housed in a 24-VQFN (4x4 mm) package and is surface-mountable. It offers high charge efficiency, reaching up to 92% at 2A and 90% at 4A, and a 93% boost efficiency at 1A for its 5V synchronous boost converter operation. The control interface is I2C, providing flexible management.

 

Key electrical specifications include a battery charge voltage range of 3.5V to 4.4V, with high accuracy for voltage (±0.5%), current (±7%), and input current regulation (±7.5%). It also provides ±2% output regulation in boost mode. Safety features include over-current, over-temperature, and over-voltage protection.
