Overview
The CAT9552HV6I-GT2 is a 16-channel LED lighting driver IC manufactured by onsemi, designed for I2C-bus control. It operates within a supply voltage range of 2.3 V to 5.5 V and features low-level output currents of 25 mA per channel. The device is housed in a TQFN-24 package with a maximum power dissipation of 1 W. It supports surface mount installation and functions reliably across an operating temperature range from -40°C to +85°C. The component has a maximum supply current of 550 uA.
Feature Summary
- Provides 16 independent channels for LED driving via I2C bus interface
- Supports low-level sink current operation for LED control
- Operates with wide input voltage compatibility from 2.3 V to 5.5 V
Applications
- LED lighting systems requiring I2C control
- General-purpose LED driver circuits
- Electronic devices utilizing low-voltage LED arrays
Procurement Notes
Verify the specific suffix 'HV6I' against official datasheets to confirm pinout and electrical characteristics match design requirements. Confirm end-of-life status and availability through authorized distributors, as this component may be discontinued or subject to limited stock constraints. Ensure thermal management solutions account for the 1 W power dissipation limit in the TQFN-24 package during final assembly planning.
Selection Notes
Select this component when a 16-channel I2C-controlled LED driver is required with low-power consumption and wide voltage tolerance. Compare against similar models like the CAT9552YI-T2 for functional equivalence. Consider the TQFN-24 package size constraints and ensure PCB layout supports the specified thermal dissipation capabilities. Verify that the 25 mA low-level output current meets the specific LED load requirements of the target application.
Part Context
This part belongs to the CAT9552 series of LED drivers from onsemi. It shares the core functionality of 16-channel I2C control but differs in specific electrical ratings and packaging variants compared to other series members. The HV6I suffix indicates specific manufacturing and performance attributes defined by the manufacturer for this particular configuration within the broader product line.
Replacement Considerations
The CAT9552YI-T2 is listed as a related component with identical functional descriptions. Verify pin-to-pin compatibility and electrical parameter alignment before substitution. Check for any differences in package type or operating temperature ranges between the two parts.
