BQ24202DGNG4

Battery Chargers Overview

The BQ24202DGNG4 is a linear Li-Ion battery charger manufactured by Texas Instruments, designed for current-limited applications. It supports single-cell lithium-ion or lithium-polymer batteries with a maximum charge current of 500 mA and a fixed 4.2-V output voltage. The device operates within an input voltage range of 4.2 V to 6 V and functions across a temperature range of -40°C to +85°C. It utilizes an MSOP-8 PowerPAD package.

Battery Chargers Feature Summary

• Integrated thermal regulation that dynamically reduces charge current to limit junction temperature
• Programmable charge termination based on input current limit detection
• Automatic recharge function triggered when battery voltage drops below the threshold

Battery Chargers Applications

• Portable devices requiring compact power management solutions
• Battery-powered equipment with limited input current availability
• Consumer electronics utilizing single-cell lithium-ion or lithium-polymer batteries

Battery Chargers Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's datasheet to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Cross-reference the component marking code with official documentation to authenticate the source and prevent counterfeit components.

Battery Chargers Selection Notes

Select this component for designs where space constraints necessitate a small MSOP-8 package and input current is strictly limited. It is suitable for low-power applications not requiring high-speed switching efficiency. Consider alternative switch-mode chargers if higher charge currents or greater energy conversion efficiency are required for the system.

Battery Chargers Part Context

This component belongs to the BQ2420x family of linear battery chargers from Texas Instruments. These devices are engineered for simplicity and minimal external component counts. They serve as cost-effective solutions for basic charging needs in portable electronics where thermal management and input current limiting are primary design constraints.

Battery Chargers Replacement Considerations

Direct replacements include other variants within the BQ2420x series, such as the BQ24200 or BQ24201, provided pin compatibility and electrical specifications align with the original design requirements.
