Description and Introduction

16-Channel, 12-Bit PWM LED Driver, 6-Bit Dot Correction with Auto Output Off Function Removed 28-HTSSOP -40 to 85 The TLC59461PWP is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Channels:** 16  
- **Output Current:** 5–60 mA per channel (adjustable via external resistor)  
- **Supply Voltage:** 3.0 V to 5.5 V  
- **Data Transfer Rate:** Up to 30 MHz  
- **Dot Correction:** 6-bit (64 steps)  
- **Grayscale Control:** 12-bit (4096 steps)  
- **Package:** HTSSOP-28 (PWP)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The TLC59461PWP is designed for LED driving applications requiring high-precision current control.  
- It supports both dot correction (for brightness uniformity) and 12-bit grayscale PWM control.  
- The device includes an error detection circuit for open or shorted LEDs.  
- It uses a serial interface for daisy-chaining multiple drivers.  

### **Features:**
- **Constant-Current Sink Outputs:** Ensures uniform LED brightness.  
- **Dot Correction:** Compensates for LED forward voltage variations.  
- **12-Bit PWM Grayscale Control:** Enables high-resolution dimming.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Open/Short LED Detection:** Enhances system reliability.  
- **Daisy-Chainable:** Supports cascading multiple drivers with a single MCU interface.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.
