BQ2031PN-A5E4

Battery Chargers Overview

The BQ2031PN-A5E4 is a monolithic CMOS integrated circuit designed as a switch-mode charge controller for lead-acid batteries. It operates from a single 5V supply and supports through-hole mounting in a 16-pin PDIP package. The device implements a two-stage constant-current charging algorithm with thermal monitoring and fault protection, including over-temperature and over-voltage safeguards.

Battery Chargers Feature Summary

• Implements a two-stage constant-current charging profile optimized for lead-acid battery chemistries
• Integrates continuous thermal monitoring to suspend charging when temperature limits are exceeded
• Provides configurable LED driver outputs for visual indication of charge status and system faults

Battery Chargers Applications

• Lead-acid battery management systems requiring switch-mode charging control
• Uninterruptible power supplies (UPS) utilizing sealed lead-acid batteries
• Solar-powered storage systems managing single-cell lead-acid banks

Battery Chargers Procurement Notes

Verify the specific suffix E4 against official Texas Instruments documentation to confirm RoHS compliance and material composition details. Ensure the PDIP-16 package variant matches your PCB footprint requirements. Cross-reference the part number with current manufacturer lifecycle status to confirm availability and active production status before finalizing procurement plans.

Battery Chargers Selection Notes
