CAT4016VSR-T2

Overview

The CAT4016VSR-T2 is a 16-channel constant current LED lighting driver IC manufactured by onsemi. It operates within a supply voltage range of 3 V to 5.5 V and delivers a maximum high-level output current of 150 mA per channel. The device is housed in a QSOP-24 package and supports surface mount installation. It functions across an operating temperature range from -40°C to +85°C, with a maximum power supply current of 10 mA.

Feature Summary

• Provides 16 independent constant current outputs for precise LED control
• Supports PWM dimming functionality for brightness adjustment
• Operates with low quiescent current consumption

Applications

• LED display drivers
• General LED lighting applications

Procurement Notes

Verify component authenticity through authorized distribution channels due to the discontinued lifecycle status. Confirm package integrity and pin alignment against the QSOP-24 specification before integration. Ensure design compatibility with the specified 3 V to 5.5 V input range and thermal requirements for the -40°C to +85°C operational window.

Selection Notes

Select this component for designs requiring multiple constant current channels without external boost circuitry. Verify that the required output current does not exceed the 150 mA limit per channel. Ensure the application environment remains within the specified industrial temperature range and that the QSOP-24 footprint aligns with the PCB layout constraints.

Part Context

This part belongs to the CAT4016 series of 16-channel constant current LED drivers. It serves as a linear shift register-based solution for driving LEDs directly from low-voltage sources. The device integrates internal current regulation to maintain consistent brightness across all channels under varying load conditions.
