BQ25622ERYKR

Battery Chargers Overview

The BQ25622ERYKR is an I2C-controlled single-cell buck battery charger from Texas Instruments. It supports a maximum input voltage of 18 V and delivers up to 2 A charge current. The device features Narrow VDC (NVDC) power path management, allowing system operation with depleted batteries. It includes an integrated 12-bit ADC for monitoring voltage, current, and temperature. The component operates within a temperature range of -40°C to +85°C and is housed in a compact 18-WQFN-HR package.

Battery Chargers Feature Summary

• Narrow VDC power path management enables instant-on functionality and system load sharing
• I2C interface allows programmable configuration of charging parameters and system settings
• Integrated 12-bit analog-to-digital converter provides high-accuracy monitoring of electrical parameters

Battery Chargers Applications

• Tablet computing devices
• Portable medical equipment
• IP cameras and EPOS systems
• Gaming and computer accessories

Battery Chargers Procurement Notes

Verify the specific suffix ER against official datasheets to confirm pinout and thermal pad configurations. Ensure compatibility with the target PCB layout and thermal requirements. Confirm that the I2C address matches the system controller expectations. Validate that the input voltage range aligns with the available power sources.

Battery Chargers Selection Notes

Select this component when NVDC power path management is required to maintain system uptime during low battery conditions. It is suitable for applications needing precise charge regulation via I2C. Consider the 18-WQFN-HR package size for space-constrained designs. Ensure the host system can support the necessary I2C communication protocol for configuration.

Battery Chargers Part Context

This part belongs to the BQ2562x series of single-cell lithium-ion chargers. It shares functional similarities with the BQ25620 but offers higher current capabilities. The series is designed for portable electronics requiring efficient charging and robust power path management. It integrates protection features such as thermal regulation and safety timers.

Battery Chargers Replacement Considerations

BQ25620RYKR is a documented alternative within the same family. Verify if the lower current rating meets application needs. Check for pin-to-pin compatibility and identical package dimensions. Confirm that the I2C register map remains compatible for direct substitution.
