The document is an introduction manual of tlc5930, which mainly introduces the characteristics and features of tlc5930, including 0.2-mA to 40-mA constant current sink capability, 12-bit output count, 1024 gray scale display, 3 brightness adjustment methods, 5 error information types and 2 gray scale clock modes.
The TLC5930 LED driver provides constant‑current sinking for up to twelve LED channels. It supports 12‑bit gray‑scale PWM control (1024 steps) and three brightness‑adjustment methods: plane, frequency‑division, and dot‑correction. The device communicates via a three‑signal DS‑Link interface and is offered in a 24‑pin HTSSOP (PWP) package to minimize board area.
Key features include thermal‑error flag, active wire‑check, LED leakage detection, and dual‑source gray‑scale clock. Recommended operating conditions, absolute‑maximum ratings, and timing diagrams are detailed in the handbook, along with pin functions and package options.
| Output current range | 0.2 mA to 40 mA |
|---|---|
| Supply voltage (VCC) | 3.0 V to 3.6 V |
| High‑level input voltage (VIH) | 2.0 V |
| Low‑level input voltage (VIL) | 0.8 V |
The device can sink a constant current from 0.2 mA up to 40 mA per channel.
It is a 12‑channel LED driver.
The part is offered in a 24‑pin HTSSOP (PWP) package, with several ordering codes such as TLC5930PWP and TLCO5930PWPR.
The maximum gray‑scale clock frequency is 25 MHz.
