概述

Description

TI TLC5928PWPR is an 8-channel constant-current LED sink driver with a simple SPI-like serial interface. It sinks current from up to eight LED strings to ground, making it suitable for displays, signage, backlighting, and indicator LEDs. Key points:
- 8 constant-current sinks; all channels share a programmable current set by an external ISET resistor.
- Serial control: SIN (data), CLK (clock), LE (latch); optional OE/BLANK for global off.
- Data is shifted in and latched to update outputs; supports cascading for more channels.
- Operates from roughly 3–5.5 V; compact PWPR packaging (TI package code).
- Uses a fixed, repeatable LED current with good accuracy; fast update times and low standby current.
Applications: LED matrices, backlighting, indicators, and other multi-LED drive needs where simple, synchronized current-controlled outputs are desired.

Features

Key features of TLC5928PWPR:
- 8-channel constant-current sink LED driver
- External IREF sets LED current per channel
- PWM/brightness control via a serial data stream (grayscale style)
- 3-wire SPI-like serial interface: SIN, SCLK, LE (latches outputs)
- Output enable/blanking control
- Wide supply range (typical 3.0–5.5 V); compatible with common logic levels
- Low quiescent current with protection features (short-circuit/thermal protection)
- Lightweight 16-pin PWPR package (suitable for compact boards)
Ideal for LED displays/backlighting requiring multiple controlled current sinks with simple serial control.

Package

28-pin HTSSOP (high‑temperature small outline) package.

Pinout

- Pin count: 28 pins (28‑pin package in the PWPR family)
- Function: 8‑channel constant‑current LED sink driver with PWM. It uses a serial input interface (data in, clock, latch) to drive 8 sink outputs (O0–O7) for LEDs. Includes control pins such as output enable/blank and a pin to set the current (ISET) via an external resistor, plus VCC and GND.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: American multinational semiconductor company that designs and manufactures integrated circuits, including analog and embedded processing ICs; one of the world’s largest semiconductor suppliers.

Application

Common applications for TLC5928PWPR:
- LED display/signage (matrix/graphic displays)
- LED backlighting for LCDs and panels
- Decorative/architectural lighting
- Automotive lighting and indicators
- LED matrix modules and multi-LED lighting projects
- General-purpose constant-current LED sink in consumer electronics

Equivalent

There isn’t an exact drop‑in cross reference for TLC5928PWPR. Closest alternatives are other 8‑channel constant‑current LED sink drivers with similar SPI/I2C interfaces, such as:
- Macroblock MBI5028 (8‑ch sink, SPI)
- Macroblock MBI5029 (8‑ch sink, SPI)
- NXP PCA962x family (16‑channel PWM with current setting)
Verify supply voltage, current, timing, and package for compatibility.
