Overview
The TLC5948DBQR is a 16-channel constant-current LED driver manufactured by Texas Instruments. It features 16-bit Enhanced Serial Pulse Width Modulation (ES-PWM) for high-resolution dimming and color mixing. The device operates within a supply voltage range of 3V to 5.5V and supports an output current of up to 60mA per channel. It utilizes a serial interface for data input and is housed in a 24-pin SSOP package, designed for operation across a temperature range of -40°C to +85°C.
Feature Summary
- Provides 16-bit ES-PWM resolution for precise individual channel control
- Supports linear shift register dimming with global brightness adjustment
- Integrates power save mode functionality for energy efficiency
Applications
- LED display systems requiring high refresh rates
- General-purpose LED lighting applications
- Electronic signage and visual displays
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm that the specific part number matches the required pinout and electrical specifications. Check for RoHS compliance status if environmental regulations apply to your project. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.
Selection Notes
Select this component when high-resolution grayscale control is necessary for multiple LEDs. Consider the 60mA output capability against total load requirements. Evaluate the serial interface compatibility with existing microcontroller or FPGA logic. Assess thermal management needs given the SSOP package constraints and operating temperature range.
Part Context
This device belongs to the TLC594x series of LED drivers from Texas Instruments. It shares architectural similarities with other members like the TLC5947 but offers distinct current drive capabilities. The series is designed for applications demanding flexible LED control without complex external circuitry, serving as a bridge between digital logic and analog LED loads.
Replacement Considerations
The TLC5948DBQR is marked as obsolete and no longer manufactured. Potential substitutes include the TLC5947 or TLC5940 series, though pinouts and current ratings may differ. Verify functional equivalence and interface compatibility before replacing.
