ISL97686IBZ

Overview

The ISL97686IBZ is a PWM-controlled LED driver IC designed for monitor and TV LCD backlight applications. It features four independent channels capable of driving 160mA per channel, with current sources rated up to 75V absolute maximum. The device operates from a 9V to 32V input supply and supports dimming modes including independent channel control via SPI, adjustable frequency PWM dimming, and VSYNC mode. It offers 10-bit dimming resolution and ±1% current matching. Integrated fault protection includes string open/short circuit, overvoltage, and over-temperature safeguards. The component is housed in a 28-lead SOIC package.

Feature Summary

Supports four independent LED current channels with integrated regulation FETs
Enables high-current operation through channel ganging capabilities
Provides comprehensive fault protection including open and short circuit detection

Applications

Monitor LCD backlighting
TV LCD backlighting
General industrial lighting
Automotive lighting

Procurement Notes

Verify the specific suffix IBZ confirms the 28-SOIC package variant. Confirm end-of-life status as public records indicate discontinuation. Ensure compatibility with existing SPI interfaces and thermal management requirements for the SOIC footprint before finalizing procurement plans.

Selection Notes

Select this component when four independent high-voltage LED channels are required for display backlighting. Consider the 9V to 32V input range and 160mA output capability. Evaluate the need for SPI-based dynamic dimming and integrated fault protection features suitable for critical display applications.

Part Context

This part belongs to the ISL97686 series of LED drivers from Renesas Electronics Corporation. It is specifically engineered for multi-channel backlighting solutions requiring precise current regulation and independent channel control. The series supports various packaging options to accommodate different board layout constraints.
