HV514WG

The HV513WG and the HV514WG are low voltage serial to high voltage (HV) 8-channel parallel converter integrated circuits (ICs). They are both configured with one low voltage serial input to 8 parallel high voltage outputs. By combining high voltage and low voltage devices in one HV514WG, they replace a large number of discrete components including multiple high voltage N-channel and Pchannel MOSFETs in applications such as driving piezoelectric transducers and flat panel displays in push-pull mode. Both can operate at 250V and feature an output current of +/-20mA per channel driving heavy loads where a larger current is required to drive large transducers and displays.

The HV514WG serial input can operate up to 8MHz. These devices were also designed to drive medium to high capacitive loads, such as Braille and weaving machine applications. The 8-channel output configuration matches Braille modular application requirements and allows for a simplified replacement procedure. Only the HV513WG features output short circuit detection that is used to prevent damage to the HV514WG. Low power level shifting and break-before-make output control circuitry that reduces overall power consumption is common to both devices. For flat panel display and printer applications, their small size and fine output pitch allow them to easily fit on the back panel of displays or on the head of printers saving valuable space and reducing cost.
