LP5522TM/NOPB

LED Driver IC Overview

The LP5522TM/NOPB is a single-channel programmable LED driver manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and delivers a constant current output of up to 20 mA. The device supports LED on-time durations ranging from 1 ms to 255 ms and provides one to three programmable pulses. It is housed in a compact six-bump DSBGA package and functions across an operating temperature range of -30°C to +85°C.

LED Driver IC Feature Summary

• Integrates internal switching capability for efficient high-side constant current regulation
• Features programmable pulse generation with configurable LED on-time intervals
• Utilizes a minimal footprint six-bump DSBGA package for space-constrained designs

LED Driver IC Applications

• Indicator lighting systems requiring precise current control
• Portable electronic devices with limited board space
• Battery-powered applications needing efficient LED driving

LED Driver IC Procurement Notes

Verify the specific revision suffix (e.g., NOPB) against the manufacturer's latest documentation to ensure compliance with current RoHS standards and material specifications. Confirm that the six-bump DSBGA package dimensions align with your PCB footprint requirements. Cross-reference the part number with official Texas Instruments channels to validate authenticity and avoid counterfeit components during sourcing.

LED Driver IC Selection Notes

Select this component when a single-channel solution with programmable timing is required. Ensure the application voltage stays within the 2.7 V to 5.5 V input range. Consider the 20 mA output limit for LED brightness requirements. The DSBGA package necessitates appropriate surface-mount assembly processes. Verify thermal performance within the specified -30°C to +85°C operational window.

LED Driver IC Part Context

This part belongs to the LP5522 series of programmable LED drivers from Texas Instruments. It is designed for simple, cost-effective LED control where complex multi-channel architectures are unnecessary. The series focuses on providing essential dimming and pulsing functions in a highly integrated form factor suitable for consumer electronics and industrial indicators.

LED Driver IC Replacement Considerations

Consult Texas Instruments documentation for direct pin-to-pin or functionally equivalent alternatives within the LP55xx family. Verify compatibility regarding package type and electrical characteristics before substitution.
