Microchip HV264TS-G: High-Voltage Serial-to-Parallel Converter with 64-Channel Output

In the realm of industrial automation, medical instrumentation, and advanced printing systems, the precise control of multiple high-voltage outputs is a critical requirement. The Microchip HV264TS-G addresses this need by serving as a sophisticated serial-to-parallel converter capable of driving up to 64 independent high-voltage channels. This integrated circuit (IC) is engineered to simplify system design while enhancing performance and reliability in demanding applications.

A standout feature of the HV264TS-G is its ability to operate with output voltages up to 100V, making it suitable for driving actuators, transducers, and other high-voltage components. The device integrates both the low-voltage logic and high-voltage output stages into a single package, significantly reducing the board space and component count compared to discrete solutions. Its serial peripheral interface (SPI) allows for straightforward communication with a host microcontroller, enabling efficient and rapid updates of the output states with minimal wiring.

The architecture of the HV264TS-G includes a 64-bit shift register, latches, and high-voltage output drivers. Data is clocked in serially via the SPI and then latched simultaneously to all outputs, ensuring precise timing synchronization across all channels. Each output can sink up to 15 mA, providing sufficient current for a wide range of loads. Additionally, the device incorporates built-in protection features such as thermal shutdown and overcurrent detection, which enhance system durability and prevent damage under fault conditions.

Another significant advantage is the device’s daisy-chain capability, allowing multiple units to be connected in series. This facilitates the control of hundreds of outputs from a single SPI port, making the solution highly scalable for large systems. The HV264TS-G is offered in a compact TSSOP package, which is conducive to high-density PCB layouts.
