L99LDLH32TR

Overview

The L99LDLH32TR is a monolithic 32-channel linear current regulator designed for automotive external OLED rear lighting applications. It features a high-side configuration suitable for driving common-cathode OLED panels, providing an output drive capability of up to 35 V. The device integrates 32 individually programmable constant current sources ranging from 1 mA to 15 mA. It includes a CAN FD Light compatible communication interface with an integrated protocol handler and a high-precision internal oscillator, eliminating the need for external quartz components.

Feature Summary

Integrates 32 independent constant current output channels with high-side configuration for precise OLED pixel control
Features an embedded CAN FD Light compatible serial interface with protocol processing capabilities for direct ECU communication
Includes an integrated high-precision oscillator that removes the requirement for external quartz crystals
Supports standalone fail-safe and bus mode operations with timeout watchdog functionality

Applications

Automotive external OLED rear lighting systems
Common-cathode OLED panel driver circuits
Automotive body control modules requiring CAN FD Light connectivity

Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm AEC-Q100 qualification status for automotive grade requirements. Ensure the operating voltage range of 5.5 V to 40 V aligns with the target vehicle power system specifications before integration.

Selection Notes

Select this component for applications requiring high channel density in a single package for OLED backlighting. Consider the integrated CAN FD Light protocol handler to reduce external microcontroller load. Evaluate the 35 V output capability against the forward voltage requirements of the selected OLED panel technology.

Part Context

This device belongs to the L99LDL series of automotive LED drivers. It complements other variants like the L99LDLL16 by offering higher channel count and advanced communication protocols. The series targets modern automotive lighting architectures demanding high reliability and diagnostic capabilities.
