CAT4002BTD-GT3

Overview

The CAT4002BTD-GT3 is a two-channel LED driver IC from onsemi, designed for portable applications. It features EZDim digital dimming interface and supports Buck/Boost topologies. Operating voltage ranges from 2.4V to 5.5V with adjustable output current up to 40mA per channel. The device utilizes a SC-70-6 surface-mount package and operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

Provides two matched low-dropout constant current sinks for precise LED brightness control
Integrates EZDim digital interface for linear dimming without external resistors
Supports flexible power supply configurations via integrated Buck and Boost converter topologies

Applications

Portable electronic device backlighting
Camera flash LED drivers
Mobile phone display illumination

Procurement Notes

Verify the specific suffix 'B' against official datasheets to confirm feature set compatibility. Confirm package designation matches SC-70-6 requirements. Ensure operating conditions align with the specified voltage and temperature ranges before integration.

Selection Notes

Select this component when dual-channel LED driving is required in space-constrained designs. The integrated topology support allows direct connection to single-cell lithium batteries or higher voltage sources without additional magnetic components.

Part Context

This part belongs to the CAT4002A/B series of programmable LED drivers. It shares functional similarities with the CAT4003 and CAT4004 series but offers a reduced two-channel configuration suitable for simpler lighting architectures requiring independent channel control.

Replacement Considerations

CAT4002ASD-GT3: Alternative package variant (SC-70-6 vs TSOT-23). Verify pinout compatibility and thermal performance differences between package types before substitution.
