Overview
The TLC5930PWP is a 12-channel LED driver IC from Texas Instruments, housed in a 24-pin HTSSOP package. It provides constant-current sink drive capability ranging from 0.2 mA to 40 mA per channel. The device supports 12-bit PWM gray-scale dimming control for each output, enabling 1024 distinct brightness levels. An external resistor sets the maximum current value for all channels. It operates within a temperature range of -20°C to +85°C and features serial data input for interface connectivity.
Feature Summary
- Provides 12 independent constant-current sink outputs with adjustable drive current
- Supports 12-bit PWM gray-scale dimming for precise brightness control
- Utilizes serial data input for simplified interface connections
- Includes over-temperature protection for enhanced reliability
Applications
- LED display systems requiring multi-channel control
- Backlight drivers for LCD panels
- General-purpose LED lighting applications
- Portable devices with limited power budgets
Procurement Notes
Verify the specific suffix (PWP) confirms the 24-pin HTSSOP package and commercial temperature grade. Ensure the order matches the exact part number to avoid confusion with tape-and-reel variants like PWPR or lead-free designations. Confirm compatibility with system voltage levels and serial interface requirements before procurement.
Selection Notes
Select this component when 12 channels of constant-current LED driving are required with high-resolution dimming. It is suitable for applications needing an external resistor to set global current limits. Consider thermal management due to the HTSSOP package size. Verify that the serial interface timing meets system controller specifications.
Part Context
This part belongs to Texas Instruments' family of LED display drivers designed for cost-effective and space-constrained applications. The TLC5930 series offers integrated PWM control to reduce microcontroller load. It is commonly used in consumer electronics where multiple LEDs need synchronized yet individually controllable brightness levels without complex external circuitry.
Replacement Considerations
Check for direct pin-compatible alternatives such as the TLC5930PWPR for different packaging formats. Verify if the TLC5930PWPG4 meets environmental compliance needs. Ensure any substitute maintains the same 12-channel architecture and current drive capabilities.
