Overview
The TCA6507PWG4 is a low-voltage LED driver IC from Texas Instruments, featuring seven independent output channels. It supports I2C and SMBus interfaces for digital control. The device operates within an input voltage range of 1.65 V to 3.6 V and delivers up to 40 mA per channel. Outputs are open-drain type with a maximum voltage rating of 5.5 V. It functions at clock frequencies up to 400 kHz and is housed in a 14-TSSOP package. The component is rated for operating temperatures between -40°C and +85°C.
Feature Summary
- Integrates seven independent low-side LED drivers controlled via standard I2C or SMBus protocols.
- Supports linear dimming capabilities through digital interface commands for precise brightness adjustment.
- Operates on low supply voltages ranging from 1.65 V to 3.6 V, suitable for battery-powered systems.
- Features open-drain outputs capable of handling load voltages up to 5.5 V independently of the supply rail.
Applications
- Portable electronic devices requiring multi-channel LED backlighting
- Low-power indicator lighting systems in consumer electronics
- I2C-controlled ambient lighting modules
- Battery-operated display illumination circuits
Procurement Notes
Verify the specific suffix G4 indicates RoHS compliance and lead-free status as per Texas Instruments documentation. Confirm the 14-TSSOP package dimensions against your PCB footprint requirements. Check current availability status as this part may be subject to lifecycle changes or obsolescence notices. Ensure I2C address configuration matches your system design constraints before procurement.
Selection Notes
Select this component when designing low-voltage LED control systems requiring multiple channels managed via I2C. It is appropriate for applications needing linear dimming without external PWM hardware. Consider the 40 mA output limit per channel for LED current requirements. Evaluate the 14-TSSOP package size for space-constrained layouts. Compare against higher voltage drivers if system rails exceed 3.6 V.
Part Context
The TCA6507 series belongs to Texas Instruments' portfolio of low-voltage LED lighting drivers. This family focuses on simplifying LED control in portable devices by integrating digital interfaces directly into the driver stage. The PWG4 variant specifically denotes the TSSOP package option with green (RoHS) compliance. It serves as a bridge between microcontroller I2C buses and LED arrays.
Replacement Considerations
TCA6507PWR is listed as a manufacturer-recommended alternative, differing primarily in tape-and-reel packaging instead of tube. Verify that the functional specifications remain identical for direct substitution. No other public substitute part numbers are confirmed in available documentation.
