Overview
The TCA6507PWRG4 is a low-voltage LED driver IC manufactured by Texas Instruments, designed for I2C and SMBus control. It features seven open-drain outputs capable of sourcing up to 40 mA each, with a maximum output voltage of 5.5 V. The device operates on a supply voltage range of 1.65 V to 3.6 V and supports communication frequencies up to 400 kHz. It is housed in a 14-pin TSSOP package and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Supports I2C and SMBus interface protocols for digital control
- Provides seven independent low-side current sink channels
- Features open-drain output configuration for flexible load connection
Applications
- LED backlighting systems
- Indicator light arrays
- Low-power LED illumination modules
Procurement Notes
Verify the specific suffix 'PWRG4' against official Texas Instruments documentation to confirm the exact package type (TSSOP-14) and tape-and-reel specifications. Ensure compatibility with system voltage levels and I2C bus speeds before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status.
Selection Notes
Select this component when a multi-channel LED driver with digital interface control is required. It is suitable for applications needing precise current sinking without complex external circuitry. Consider the 40 mA per channel limit and the 5.5 V output voltage ceiling when designing the LED load network. Verify that the I2C address configuration meets system addressing requirements.
Part Context
This part belongs to the TCA6507 series of LED drivers from Texas Instruments. It is specifically engineered for low-voltage operation and digital dimming or switching applications. The device integrates control logic and power stages into a single compact package, simplifying PCB layout for LED management tasks in consumer and industrial electronics.
Replacement Considerations
Consult Texas Instruments official substitution guides for verified alternatives. Generic equivalents may not match the specific I2C protocol implementation or current sinking characteristics.
