Description and Introduction

Serially Interfaced, +2.7V to +5.5V, 5- and 8-Digit LED Display Drivers The MAX6951CEE+ is a versatile LED display driver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX6951CEE+  
- **Type:** LED Display Driver  
- **Package:** 16-QSOP (150 mil)  
- **Operating Voltage:** 2.7V to 5.5V  
- **Number of Segments:** Up to 28 (7-segment digits) or 56 (individual LEDs)  
- **Interface:** 4-wire SPI-compatible serial interface  
- **Max Clock Frequency:** 26 MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Dimming Control:** 16-step digital brightness control  
- **Current per Segment:** Adjustable via external resistor  

### **Descriptions:**  
The MAX6951CEE+ is a compact, high-performance LED driver designed to control up to 7-segment displays or discrete LEDs. It integrates a serial interface, reducing the need for multiple I/O pins from the microcontroller. The device supports multiplexed displays with built-in decoding, simplifying the design of LED-based applications.  

### **Features:**  
- Supports multiplexed common-cathode LED displays  
- On-chip segment current limiting with adjustable brightness  
- Built-in font decoding for 7-segment digits  
- Configurable as 28 segments (7 digits) or 56 discrete LEDs  
- Low-power shutdown mode  
- High-speed SPI-compatible interface (up to 26 MHz)  
- Robust ESD protection (±15kV HBM)
