• Provides accurate trickle charge functionality for deeply discharged batteries
• Includes comprehensive protection against over-voltage, over-current, and thermal faults

Battery Chargers Applications

• Portable consumer electronics requiring single-cell Li-Ion/Polymer charging
• Battery-powered devices with limited power budget constraints
• Applications necessitating high reliability and compact form factor

Battery Chargers Procurement Notes

Verify the specific suffix RHDT corresponds to the tape and reel packaging configuration. Confirm that the component meets RoHS3 compliance standards as indicated by manufacturer documentation. Ensure compatibility with the intended PCB layout regarding the exposed thermal pad requirements for adequate heat dissipation during operation.

Battery Chargers Selection Notes

Select this component when designing systems with single-cell lithium-based chemistries. Consider the 28V input tolerance for robustness against transient spikes. Evaluate the thermal performance characteristics given the small package size and high current capability to ensure stable operation under varying load conditions.

Battery Chargers Part Context

This part belongs to the BQ2474x series of battery chargers from Texas Instruments. It shares functional similarities with the BQ24742 but differs in cell count support and specific parameter configurations. The series is characterized by integrated power switches and programmable charging profiles suitable for space-constrained designs.

Battery Chargers Replacement Considerations

Direct substitutes may include other single-cell chargers from the same family with compatible pinouts. Verify equivalent input voltage ranges and thermal specifications before substitution. Cross-reference datasheets to ensure identical protection feature sets and communication interfaces if applicable.
