Overview
The CAT9532WI-T1 is a 16-bit programmable LED dimmer IC manufactured by onsemi. It features an I2C interface for control and supports PWM dimming with brightness control capabilities. The device operates within a supply voltage range of 2.3 V to 5.5 V and delivers a low-level output current of 25 mA per channel. It utilizes Boost and Buck topologies for adjustable output voltage. The component is housed in a 24-SOIC package (0.295" width) and functions within a temperature range of -40°C to +85°C, consuming a maximum power dissipation of 1 W.
Feature Summary
- Integrates 16 independent channels for linear LED dimming control via I2C communication.
- Supports Pulse Width Modulation (PWM) dimming for precise brightness adjustment.
- Incorporates Boost and Buck converter topologies to manage adjustable output voltages.
- Designed for low-power operation with integrated interrupt functionality.
Applications
- LED lighting driver systems requiring multi-channel control
- I2C/SMBus expander applications with LED dimming capabilities
- General-purpose LED brightness control circuits
Procurement Notes
Verify the specific suffix 'T1' against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the SOIC-24 package dimensions match your PCB footprint requirements. Cross-reference the operating temperature range (-40°C to +85°C) with your system's environmental conditions. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.
Selection Notes
Select this component when a 16-channel LED driver with I2C interface is required. It is suitable for designs needing 25 mA output current per channel. Consider the 2.3 V to 5.5 V input voltage range for compatibility with your power supply. The SOIC-24 package is appropriate for surface-mount assembly processes. Evaluate the need for Boost/Buck topology if voltage conversion is necessary for the LED load.
Part Context
The CAT9532 series belongs to onsemi's portfolio of LED lighting drivers and I/O expanders. This specific model integrates LED dimming functionality with standard I2C bus connectivity. It serves as a bridge between digital controllers and analog LED loads, offering a compact solution for managing multiple LEDs in space-constrained electronic devices.
Replacement Considerations
Consult onsemi's official cross-reference data for verified substitutes. Generic equivalents may not support the specific I2C protocol or 25 mA output current characteristics. Verify pinout compatibility and package dimensions before substitution.
