Description and Introduction

16-Channel 12-bit PWM with 7-bit Dot Correction 28-HTSSOP -40 to 85 The TLC5942PWP is a 16-channel, constant-current sink LED driver manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Channels:** 16  
- **Output Current:** 30 mA per channel (adjustable via external resistor)  
- **Supply Voltage (VCC):** 3.0 V to 5.5 V  
- **Logic Input Voltage:** 3.3 V or 5 V compatible  
- **Dot Correction (DC):** 64-step (6-bit) adjustable per channel  
- **Grayscale (GS) PWM Control:** 4096-step (12-bit) resolution  
- **Data Transfer Rate:** Up to 30 MHz  
- **Package:** HTSSOP-28 (PWP)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The TLC5942PWP is designed for LED driving applications requiring high precision and brightness control.  
- It includes dot correction to compensate for LED brightness variations and grayscale PWM for smooth dimming.  
- The device supports daisy-chaining for multiple ICs in large LED matrix applications.  
- It features a built-in error detection circuit for open-LED and shorted-LED conditions.  

### **Features:**  
- **Constant-Current Sink Outputs:** Ensures uniform LED brightness.  
- **Dot Correction:** Adjusts brightness variations between LEDs.  
- **High Grayscale Resolution:** 12-bit PWM for smooth dimming.  
- **Error Detection:** Flags open or shorted LED conditions.  
- **Daisy-Chaining Capability:** Supports cascading multiple drivers.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.  
- **Thermal Shutdown Protection:** Prevents overheating.  

This information is strictly factual and derived from Texas Instruments' documentation.

Application Scenarios & Design Considerations

16-Channel 12-bit PWM with 7-bit Dot Correction 28-HTSSOP -40 to 85

Alternative Part Number

  • TLC5941PWP --: Same TLC594x family, 16-channel LED driver in the same HTSSOP-28 package with similar serial interface, making it a close functional substitute.
  • TLC5947DAP --: 24-channel constant-current LED driver from the same TLC59xx family, offering more channels and comparable PWM control for LED driving applications.
  • PCA9685PW --: 16-channel 12-bit PWM LED controller with I2C interface in TSSOP-28, a widely used alternative for multi-channel LED dimming when pin-level compatibility is not mandatory.
  • LED1642GWPTR --: 16-channel constant-current LED driver with error detection and serial interface, suitable as a functional replacement.
  • IS31FL3236A-QFLS2-TR --: 36-channel constant-current LED driver with I2C control, offering comparable PWM LED driving capability for similar applications.
