Microchip Technology HV518PJ-G High Voltage Serial to Parallel Converter

The HV518PJ-G is a robust high voltage serial to parallel converter produced by Microchip Technology, designed to cater to a wide array of applications requiring high voltage outputs. This device is particularly well-suited for driving vacuum fluorescent displays (VFDs), but its versatility allows it to be integrated into various other applications such as LED displays, print heads, and other industrial control systems.

Constructed with an 8-bit shift register and latch, the HV518PJ-G can convert serial input data into parallel output format, thereby facilitating the control of up to 32 outputs. Each output can sustain a voltage of up to 80V, and the device can source up to 500mA of current, which is substantial for driving multiple high-voltage components simultaneously.

The HV518PJ-G operates over a broad temperature range, making it suitable for industrial environments. With a temperature range from -40°C to +85°C, this device ensures reliable performance even under extreme conditions. Its package, a 44-pin PLCC (Plastic Leaded Chip Carrier), provides a compact footprint while ensuring adequate pin spacing for high-voltage applications, thus preventing electrical arcing and ensuring device longevity.

Featuring a CMOS technology that ensures low power consumption, the HV518PJ-G is efficient and can be powered by a single 5V supply, which simplifies the power design of the system it is integrated into. The serial interface is compatible with SPI, QSPI™, and MICROWIRE, allowing for easy integration with most microcontrollers.

For added safety, the HV518PJ-G incorporates latch-up protection, which prevents device failure due to high current caused by unintended short circuits or other fault conditions. This protection, along with its high voltage capability, makes the HV518PJ-G a reliable choice for designers looking to incorporate high voltage outputs into their systems.

In summary, the HV518PJ-G from Microchip Technology is a versatile, high-voltage serial to parallel converter that offers reliability and efficiency for a wide range of applications. Its integration-friendly interface and robust design ensure it is a go-to choice for engineers requiring high voltage output control.
