Description and Introduction

Microprocessor Supervisory Circuits The MAX692A is a high-voltage, serial-interfaced, vacuum fluorescent display (VFD) tube driver manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage (V+):** +4.5V to +5.5V  
- **High-Voltage Output (VPP):** Up to 76V  
- **Serial Interface:** SPI-compatible (3-wire)  
- **Number of Outputs:** 20 (grid and segment drivers)  
- **Output Current:** 100mA (peak) per output  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 24-pin DIP or SO  

### **Descriptions:**  
The MAX692A is designed to drive VFD displays efficiently with a serial interface, reducing the number of microcontroller I/O pins required. It integrates both grid and segment drivers, supporting multiplexed VFD applications.  

### **Features:**  
- **High-Voltage Generation:** On-chip charge pump for VPP generation.  
- **Low Power Consumption:** Optimized for battery-powered applications.  
- **Serial Data Input:** Compatible with SPI/MICROWIRE interfaces.  
- **Output Protection:** Built-in current limiting and thermal shutdown.  
- **Cascadable:** Supports daisy-chaining for larger displays.
