Overview
The TLC5904PZP is a 16-channel LED driver manufactured by Texas Instruments, housed in a 100-pin HTQFP package. It operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -20°C to +85°C. The device provides constant current output with a maximum sink current of 120 mA per channel and features a 12-bit grayscale PWM dimming capability. It utilizes a serial interface for data input and includes an XLAT pin for latch control.
Feature Summary
- Provides independent 12-bit grayscale PWM dimming for each of the 16 channels
- Features constant current sinks with programmable output current via a single external resistor
- Supports daisy-chaining multiple devices through a serial interface for expanded channel counts
Applications
- LED backlighting systems for displays
- General-purpose LED lighting arrays
- Multiplexed LED indicator panels
Procurement Notes
Verify the specific suffix PZP corresponds to the HTQFP-100 package and commercial temperature grade (-20 to +85 C) as documented in official Texas Instruments datasheets. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process. Ensure the ordering part number matches the exact package variant required for your PCB footprint design.
Selection Notes
Select this component when a high channel count with individual PWM control is required without external microcontroller processing overhead. The fixed 12-bit resolution suits applications requiring smooth brightness transitions. Consider the thermal dissipation capabilities of the HTQFP-100 package if driving multiple channels at maximum current simultaneously.
Part Context
This device belongs to the TLC5904 series of LED drivers designed for high-density lighting applications. It integrates grayscale and common cathode pulse width modulation (PWM) dimming into a single chip, reducing the need for complex external logic or additional controller pins.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative drivers based on pinout, electrical specifications, and package dimensions before substitution.
