BQ25790YBGR

Battery Chargers Overview

The BQ25790YBGR is a fully integrated switch-mode buck-boost charger designed for 1 to 4-cell Li-ion and Li-polymer batteries. It features an I2C interface and supports input voltages up to 24 V with a maximum charge current of 5 A. The device integrates four switching FETs, a power path controller, and system load switches. It operates within a temperature range of -40°C to +85°C and utilizes a 56-pin XFBGA package.

Battery Chargers Feature Summary

• Integrates four switching FETs and a power path controller for efficient charging
• Supports NVDC (Non-Volatile Dual-Use) architecture for seamless system power management
• Includes programmable battery charge termination timer and voltage regulation

Battery Chargers Applications

• Portable computing devices
• Industrial equipment
• Medical devices

Battery Chargers Procurement Notes

Verify the specific suffix YBGR against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure compatibility with the required 56-pin XFBGA footprint during PCB layout. Confirm that the intended application environment falls within the specified operating temperature range of -40°C to +85°C before finalizing procurement.

Battery Chargers Selection Notes

Select this component when a compact solution for 1 to 4-cell battery charging is required. It is suitable for applications needing high efficiency through integrated FETs and precise control via I2C. Consider the thermal performance of the XFBGA package relative to the expected 5 A charge current in the target enclosure design.

Battery Chargers Part Context

This part belongs to Texas Instruments' family of highly integrated battery chargers. It is distinct from evaluation boards like the BQ25790EVM, which are used for testing rather than end-product integration. The device serves as a core power management IC for portable electronics requiring robust charging profiles.

Battery Chargers Replacement Considerations

Consult the manufacturer's cross-reference documentation for verified alternative part numbers. Do not assume functional equivalence with other models in the series without verifying pin compatibility and electrical parameters.
