DS3881E+TR/C

Overview

The DS3881E+TR/C is a single-channel automotive CCFL controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.75V to 5.25V and draws a supply current of 12 mA. The device supports frequencies between 40kHz and 100kHz and features dimming capability. It is housed in a 24-TSSOP package with dimensions of 0.173 inches (4.40mm) width. The component functions reliably across an operating temperature range from -40°C to +105°C.

Feature Summary

• Single-channel control architecture for cold cathode fluorescent lamps
• Integrated dimming functionality for backlight adjustment
• Automotive-grade thermal performance rating

Applications

• Automotive liquid crystal display backlighting systems
• CCFL inverter driver circuits
• Industrial display illumination control

Procurement Notes

Verify the specific suffix configuration against official datasheets, as packaging designators such as TR or C denote distinct handling methods. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply conditions or end-of-life restrictions. Ensure compliance with RoHS directives and check for any REACH material declarations prior to final procurement decisions.

Selection Notes

Select this component when a single-channel solution is required for automotive CCFL applications. Verify that the 24-TSSOP surface-mount package fits the board layout constraints. Ensure the system power supply remains stable within the 4.75V to 5.25V range. Confirm that the operating environment stays within the specified -40°C to +105°C temperature limits for reliable operation.

Part Context

This part belongs to the DS3881/DS3882 family of CCFL controllers designed for display backlighting. The DS3881 variant specifically provides single-channel control, whereas related models like the DS3882 offer dual-channel capabilities. Both share similar operational principles and are intended for high-reliability environments requiring precise lamp management.
