ADP3820ART-4.1-RL7

Overview

The ADP3820ART-4.1-RL7 is a precision single-cell lithium-ion battery charge controller manufactured by Analog Devices Inc. It operates within the ADP3820 series and utilizes a SOT-23-6 surface-mount package. The device provides a fixed output voltage of 4.1 V with a charging current capability of 1 mA. Designed for low-power applications, it features a shutdown current of 1 µA to minimize power consumption during standby modes. The component supports operation across an industrial temperature range from -40°C to +85°C. It requires an external Power PMOS device to form the complete charging circuit.

Feature Summary

Precision single-cell Li-Ion battery charge controller architecture
Ultra-low shutdown current for extended battery life in standby
High accuracy voltage regulation for safe cell charging
Compact SOT-23-6 surface-mount packaging

Applications

Portable electronic devices requiring precise single-cell battery management
Low-power consumer electronics with strict standby current limits
Industrial sensors utilizing lithium-ion power sources
Medical devices demanding high charging accuracy and safety

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check current availability as supply may be limited. Ensure the external Power PMOS selection matches the controller's specifications for proper circuit integration.

Selection Notes

Select this component when designing circuits for single-cell lithium-ion batteries requiring minimal quiescent current. The fixed 4.1 V output suits specific cell chemistries. Consider the 1 mA current limit for small-capacity cells. Evaluate thermal performance within the specified -40°C to +85°C operating range. Verify compatibility with the required external PMOS transistor.

Part Context

This part belongs to the ADP3820 family of battery chargers from Analog Devices. The suffix '4.1' indicates the specific 4.1 V output variant. The 'ARTZ' designation refers to the lead-free SOT-23-6 package type. The '-RL7' suffix typically denotes reel packaging configuration for automated assembly processes.
