Overview
The CAT4016HV6-GT2 is a 16-channel LED lighting driver IC manufactured by onsemi. It utilizes a boost topology to drive LEDs with an output current of 100 mA per channel. The device operates within a supply voltage range of 3 V to 5.5 V and supports a maximum output voltage of 5.5 V. It features a four-wire interface and functions at a working frequency of 25 MHz. The component is housed in a TQFN-24 package and is rated for operation between -40°C and +85°C.
Feature Summary
- Provides independent constant current control for sixteen LED channels
- Integrates a boost converter topology for efficient LED driving
- Supports four-wire serial interface for configuration and control
Applications
- LED lighting systems requiring multi-channel current regulation
- General illumination applications utilizing boost-driven LED arrays
- Electronic devices needing compact, high-density LED driver solutions
Procurement Notes
Verify the specific ordering suffix GT2 to confirm the tape and reel packaging format. Ensure the selected variant matches the required thermal performance for the intended enclosure. Cross-reference the datasheet electrical characteristics against the target application's power supply constraints. Confirm RoHS compliance status if environmental regulations apply to the final product assembly.
Selection Notes
Select this component when a high channel count is required within a small footprint. The boost topology is suitable for applications where the LED forward voltage exceeds the supply rail. Evaluate the thermal dissipation capabilities of the TQFN-24 package relative to the total power load. Consider the 25 MHz interface speed for system timing requirements.
Part Context
This part belongs to the CAT4016 series of LED drivers from onsemi. The series focuses on providing flexible solutions for various LED lighting architectures. The HV designation typically indicates high-voltage handling capabilities or specific internal regulator configurations compared to standard variants.
Replacement Considerations
Consult official cross-reference lists for direct pin-compatible alternatives. Verify that any substitute maintains the 16-channel architecture and 100 mA output capability. Ensure the replacement package matches the TQFN-24 form factor for board compatibility.
