Description and Introduction

20-Channel Serial-Input Vacuum-Fluorescent Display Driver for Anode/Grid The HV5812P is a high-voltage, serial-input, latched driver manufactured by SUPERTEX (now part of Microchip Technology). Here are its key specifications:  

- **Type**: 20-channel serial-input, latched driver  
- **Voltage Range**:  
  - Logic Supply Voltage (VDD): 4.5V to 5.5V  
  - High-Voltage Output Supply (VPP): Up to 200V  
- **Output Current**: 10mA per channel (sink)  
- **Logic Inputs**: CMOS/TTL compatible  
- **Serial Data Interface**:  
  - Clock frequency up to 10MHz  
  - Data shifted in on rising edge of CLK  
- **Latch Function**: Latches data on rising edge of LATCH input  
- **Package**: 28-pin DIP or SOIC  
- **Applications**: Used in printers, industrial controls, and other high-voltage switching applications.

Application Scenarios & Design Considerations

20-Channel Serial-Input Vacuum-Fluorescent Display Driver for Anode/Grid

Alternative Part Number

  • HV507 --: Microchip acquired Supertex and continues the high-voltage driver line; HV507 is a similar 64-channel high-voltage driver with comparable serial interface and output ratings, making it a strong functional substitute.
  • HV518 --: Another Supertex-lineage 80-channel high-voltage driver from Microchip with similar shift-register interface and high-voltage push-pull outputs, suitable where channel count and voltage ratings align.
  • STP16CP05 --: A 16-channel constant-current LED driver with serial input that can serve lower-channel-count applications; requires checking voltage and current ratings but offers a different-series alternative from a major supplier.
  • MAX6921AWI+ --: High-voltage 20-output serial shift register driver in a similar function class, widely used as a drop-in replacement for VFD driver applications.
  • STP16CP05MTR --: 16-channel constant-current LED sink driver with serial interface, suitable alternative when fewer outputs are acceptable.
  • TLC5928IDW --: 16-channel constant-current LED driver with serial control, offering comparable drive capability and easy sourcing.
