Battery Chargers datasheet and documents for BQ25620RYKR

BQ25620RYKR

Battery Chargers Overview

The BQ25620RYKR is an I2C-controlled single-cell battery charger IC designed for lithium-ion and lithium-polymer batteries. It features a maximum input voltage of 18V and supports a programmable charge current up to 2A. The device integrates narrow VDC (NVDC) power path management, allowing simultaneous system powering and battery charging while maintaining VSYS below VBAT. It includes an integrated ADC for monitoring input voltage, battery voltage, and temperature, alongside OTG output capabilities.

Battery Chargers Feature Summary

I2C-controlled configuration for system setup and status reporting
Narrow VDC power path management for parallel system load and battery charging
Integrated analog-to-digital converter for precise parameter monitoring
On-the-go (OTG) output functionality for reverse boosting

Battery Chargers Applications

Smartphones and mobile phones
Tablets and portable computing devices
Portable medical equipment
Wearable electronics

Battery Chargers Procurement Notes

Verify the specific suffix RYKR against the official Texas Instruments datasheet to confirm package type and tape/reel specifications. Ensure compatibility with I2C interface requirements and NVDC power path design constraints. Confirm RoHS compliance status and moisture sensitivity level prior to integration into production assemblies.

Battery Chargers Selection Notes

Select this component for applications requiring efficient single-cell charging with integrated power path management. The I2C interface allows flexible configuration of charge parameters and system limits. Consider the 18V maximum input rating for adapter compatibility and the need for external thermistor support for battery temperature monitoring during operation.

Battery Chargers Part Context
