The HV826MG301 is a high-voltage, serial-to-parallel converter IC from Supertex (now Microchip Technology). This device is primarily designed for driving electroluminescent (EL) lamps, but can also be used in other applications requiring high-voltage outputs. It converts serial data into parallel high-voltage outputs, allowing for control of multiple segments or pixels of an EL display with minimal control lines.

Additional Details

The HV826MG301 is typically available in a surface-mount package. It accepts serial data and converts it into parallel high-voltage outputs. These outputs can then be used to drive individual segments or pixels of an EL display, allowing for complex patterns and animations to be displayed. The device's high output voltage capability makes it suitable for driving EL lamps, which require relatively high voltages to operate. The serial data input minimizes the number of control lines required, simplifying the wiring and reducing the complexity of the control circuitry. The low quiescent current reduces power consumption, which is particularly important in battery-powered applications. The CMOS logic compatibility allows for easy interfacing with standard CMOS logic circuits. This IC is essential for applications requiring efficient and compact control of high-voltage loads, particularly EL displays.
