CAT4016HV6-T2

Overview

The CAT4016HV6-T2 is a 16-channel constant current LED lighting driver IC manufactured by onsemi. It utilizes a boost topology to drive LEDs with an output current of 80 mA per channel. The device operates within a supply voltage range of 3 V to 5.5 V and supports a switching frequency of 25 MHz. It is housed in a TQFN-24 package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides 16 independent channels for constant current LED driving
• Integrates a boost converter topology for efficient power management
• Supports PWM dimming control for brightness adjustment

Applications

• LED backlighting systems
• General LED illumination circuits
• Portable electronic display modules

Procurement Notes

Verify the specific suffix 'HV6' against the official datasheet to confirm high-voltage capabilities and pinout compatibility. Confirm RoHS compliance status through the manufacturer's documentation. Ensure the TQFN-24 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring multiple independently controlled LED channels with a boost architecture. Consider the 80 mA output current limit and the 3 V to 5.5 V input voltage range. Evaluate thermal performance within the specified -40°C to +85°C operating range for the intended application environment.

Part Context

This part belongs to the CAT4016 series of LED drivers from onsemi, designed for multi-channel applications. It shares functional similarities with other members of the CAT4106 family but offers specific configuration options for high-voltage or specialized LED driving needs within the same product line ecosystem.

Replacement Considerations

Check for direct cross-references such as CAV4016 variants. Verify electrical parameters and pinouts against alternative 16-channel boost LED drivers if sourcing constraints exist.
