Microchip Technology's HV5812WG-G High-Voltage Serial-to-Parallel Converter

The HV5812WG-G, manufactured by Microchip Technology, is a robust integrated circuit designed to interface low-voltage digital signals with high-voltage drive applications. This high-voltage serial-to-parallel converter is particularly suitable for driving vacuum fluorescent displays (VFDs), as well as other applications requiring high-voltage switching, such as industrial control systems, medical equipment, and automotive displays.

Constructed with a 20-channel output, the HV5812WG-G is capable of operating with an output voltage up to 80V and an output current of 45mA per channel, making it an ideal choice for managing multiple high-voltage lines. Its serial input data is clocked into the device's internal shift register on the rising edge of the serial clock input (CLK). The data is then latched into an internal storage register on a low-to-high transition of the storage register clock (LE).

The HV5812WG-G stands out with its CMOS technology, which ensures low power consumption while maintaining high data integrity during communication. Additionally, it features an output pull-down resistor to ensure that outputs are off at power-up, a safety feature that is critical in preventing unintended activation of connected devices.

Reliability is a key aspect of the HV5812WG-G, with its thermal protection circuitry that shuts down the device's outputs in the event of an over-temperature condition, protecting both the converter and the system it is a part of. The device is also designed with latch-up protection, further enhancing its robustness in various working environments.

Encased in a 28-lead, 0.300-inch wide, plastic leaded chip carrier (PLCC) package, the HV5812WG-G is not only powerful but also compact, enabling it to fit into space-constrained applications without sacrificing performance. Its green (RoHS compliant) packaging also indicates Microchip Technology's commitment to environmental sustainability.

Overall, the HV5812WG-G from Microchip Technology is a versatile and reliable solution for high-voltage digital-to-analog conversion, offering designers a high-performance option for their advanced electronic systems.
