DS3923T+T

Current Regulation/Management Overview

The DS3923T+T is a current mirror integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within an input voltage range of 2.85 V to 3.63 V and delivers an output current of 2 mA. The device provides a precision accuracy of ±0.5 dB. Designed for surface mount installation, it is housed in a 24-TQFN (3.5x3.5) package with exposed pad. The component supports an extended operating temperature range from -40°C to +95°C.

Current Regulation/Management Feature Summary

• Provides precise current mirroring functionality with specified accuracy
• Operates on low single-supply voltage ranges suitable for portable systems
• Features compact surface-mount packaging for space-constrained designs

Current Regulation/Management Applications

• Current regulation in battery-powered devices
• Biasing circuits in portable electronics
• Power management subsystems requiring precise current replication

Current Regulation/Management Procurement Notes

Verify the specific suffix and tape-and-reel configuration against official datasheets before ordering. Confirm that the 24-TQFN footprint matches your PCB layout requirements. Ensure supply chain sources provide genuine components with traceable documentation to avoid counterfeit risks associated with limited availability parts.

Current Regulation/Management Selection Notes

Select this component when precise current replication is required within a narrow voltage window. The ±0.5 dB accuracy makes it suitable for applications demanding consistent current distribution. Consider the thermal performance of the TQFN package if high ambient temperatures are expected within the specified operational range.

Current Regulation/Management Part Context

This part belongs to the DS3923 series of current mirrors. It is distinct from other Maxim Integrated power management ICs like the DS3920 or DS3911 which serve different monitoring or conversion roles. The TQFN package distinguishes it from larger through-hole or standard QFN variants found in related product lines.
