Overview
The ISL97694AIRTZ-T is a six-channel LED lighting driver IC manufactured by Renesas Electronics Corporation. It utilizes a boost topology to drive LEDs from a single-cell Li-Ion battery source, supporting an input voltage range of 2.4 V to 5.5 V and delivering up to 40 mA per channel. The device features 12-bit PWM dimming control and operates within a switching frequency range of 400 kHz to 1.5 MHz. It provides an output voltage capability of 26 V and includes open LED protection. The component is housed in a TQFN-20 package and functions reliably across a temperature range of -40°C to +85°C.
Feature Summary
- Six independent output channels for multi-zone LED driving
- Integrated 12-bit pulse width modulation dimming control
- Built-in open LED protection circuitry
Applications
- Li-Ion battery powered LED lighting systems
- Portable LED illumination devices
- Multi-channel backlight applications
Procurement Notes
This component is identified as End-of-Life (EOL) with discontinued status. Availability is restricted, and Mouser indicates non-sale in certain regions. Verify current stock levels and lead times through authorized distributors before design finalization. Consider obsolescence management strategies due to the lack of future production commitments.
Selection Notes
Select this part for designs requiring six synchronized LED channels driven by a single-cell lithium-ion battery. Ensure the application supports the specified 400 kHz to 1.5 MHz switching frequency and requires 12-bit resolution for brightness control. The TQFN-20 package and -40°C to +85°C operating range must align with thermal and spatial constraints.
Part Context
The ISL97694A series belongs to Renesas' portfolio of specialized LED lighting drivers designed for portable applications. This specific model extends functionality to six channels, differing from four-channel variants like the ISL97692. It shares architectural similarities with other Intersil-derived LED drivers but is distinct in its channel count and specific boost converter configuration for single-cell operation.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, direct pin-to-pin replacements are not explicitly listed. Designers should consult official cross-reference tools or contact Renesas support for validated alternatives.
