Overview
The CAT4106HV4-GT2 is a four-channel LED driver IC manufactured by onsemi, utilizing a boost topology to drive up to ten LEDs in series. It operates within an input voltage range of 3 V to 5.5 V and supports a maximum output voltage of 36 V. The device delivers a high-level output current of 175 mA and a low-level output current of 10 mA per channel. Designed for surface-mount applications, it is housed in a TQFN-16 package. The component functions reliably across a temperature range of -40°C to +85°C with a switching frequency of 1 MHz.
Feature Summary
- Integrates four independent constant-current channels for multi-string LED control
- Incorporates PWM dimming capability for precise brightness regulation
- Includes open LED protection mechanisms to enhance system reliability
Applications
- LED lighting driver circuits requiring boost topology
- Portable electronic devices with limited power supply voltages
- General illumination systems utilizing multiple LED strings
Procurement Notes
Verify the obsolescence status prior to procurement, as this component is listed as end-of-life and subject to manufacturer discontinuation. Confirm that the TQFN-16 package dimensions align with existing PCB footprints. Ensure compatibility with the specified 3 V to 5.5 V input range and 175 mA current requirements for the target application design.
Selection Notes
Select this component when a four-channel boost driver is required for driving series-connected LED arrays from low-voltage sources. Consider the 175 mA current limit and 36 V output ceiling against load requirements. Evaluate the TQFN-16 package for thermal management and space constraints. Verify that the operating temperature range meets environmental specifications.
Part Context
This part belongs to the CAT4106 series of LED drivers from onsemi. It is specifically designed for applications needing multiple independent channels with boost conversion capabilities. The HV4 suffix indicates specific pinout or feature variations within the family. It serves as a solution for compact LED lighting designs requiring efficient power management.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, alternative sourcing should focus on verifying functional equivalents with matching channel counts, boost topology, and package types.
