LED Driver IC datasheet and documents for LP5891RRFR

LP5891RRFR

LED Driver IC Overview

The LP5891RRFR is a Texas Instruments LED lighting driver IC featuring a 48-channel, 16-line matrix architecture. It operates on a supply voltage range of 2.5 V to 5.5 V and supports PWM dimming with up to 16-bit grayscale control. The device integrates intelligent power-saving modes, reducing current consumption significantly during low-power states. Packaged in a VQFN-76 format, it functions within an operating temperature range of -40°C to +85°C.

LED Driver IC Feature Summary

Integrates 48 constant current sources and 16 scan FETs for high-density LED matrix driving
Supports up to 16-bit PWM grayscale control with independent color brightness adjustment
Features built-in diagnostic capabilities including open circuit and short circuit detection

LED Driver IC Applications

Mini and micro LED matrix displays
RGB LED backlighting for gaming keyboards
LED light panels with local dimming capabilities
Broadcast and audio mixing equipment indicators

LED Driver IC Procurement Notes

Verify the specific suffix RRFR against official datasheets to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and thermal management needs. Confirm that the intended application does not require automotive AEC-Q100 certification, as this variant differs from the Q1 series.

LED Driver IC Selection Notes

Select this component for applications requiring high channel density and precise grayscale control without automotive qualification. Compare against the LP5891-Q1 if automotive standards are mandatory. Evaluate the need for stackable configurations to support larger display matrices beyond the single-device capacity.

LED Driver IC Part Context

This part belongs to the LP5891 family of highly integrated LED matrix drivers designed for complex display architectures. It serves as a core driver element for systems requiring extensive channel counts within a compact footprint, enabling scalable designs through daisy-chain connectivity options.
