Overview
The AUR9801DGD is a single-cell lithium-ion and lithium-polymer battery charger integrated circuit manufactured by Diodes Incorporated. It operates within a supply voltage range of up to 5.5V and supports a maximum programmable charging current of 1A. The device is designed for a battery pack voltage of 4.2V and functions reliably across an operating temperature range of -40°C to +85°C. It utilizes a 10-WDFN package with exposed pad, specifically sized at 3x3mm, suitable for surface-mount assembly in compact portable electronics.
Feature Summary
- Supports constant-current/constant-voltage charging profiles for single-cell lithium-ion and lithium-polymer batteries
- Features programmable charging current capability for flexible power management
- Integrated thermal regulation to manage heat dissipation during the charging cycle
Applications
- Portable consumer electronics requiring single-cell battery charging
- Mobile communication devices
- Wearable technology with limited board space
Procurement Notes
Verify the specific suffix 'DGD' against the official Diodes Incorporated datasheet to confirm exact packaging and tape-and-reel specifications. Ensure the component meets the required RoHS compliance standards for your target market. Cross-reference the 10-WDFN footprint dimensions with your PCB layout guidelines to guarantee accurate placement and soldering reliability during manufacturing.
Selection Notes
Select this component when a single-cell Li-Ion or Li-Po charging solution is required with a maximum input voltage of 5.5V. It is appropriate for designs needing a 1A charge current limit and operation in temperatures down to -40°C. Consider the 10-WDFN package size if board real estate is constrained compared to larger packages like WSON or QFN variants.
Part Context
This part belongs to the AUR98xx series of battery chargers from Diodes Incorporated. The series focuses on efficient power management for portable devices. The AUR9801 variant specifically targets single-cell applications, distinguishing it from multi-cell solutions in the broader portfolio. It complements other PMIC offerings by providing dedicated charging functionality.
Replacement Considerations
Check for direct substitutes within the AUR98xx family, such as the AUR9801CGD, noting that package differences may exist. Verify pin compatibility and electrical parameters before substituting with other single-cell chargers from different manufacturers.
