The Microchip Technology HV823LG-G is a high-voltage driver IC designed for EL lamps, processed with HVCMOS technology. It supports a wide operating supply voltage range from 2.0V to 9.5V and offers DC to AC conversion with a typical output voltage of 180V peak-to-peak. This device is capable of driving large output loads, typically up to 50nF, and allows for adjustable output lamp frequency to control lamp color, life, and power consumption. It also features an adjustable converter frequency to optimize power consumption and eliminate harmonics.
The HV823LG-G integrates two internal oscillators, a switching MOSFET, and a high-voltage EL lamp driver. The frequency of the switching converter MOSFET is set by an external resistor connected between the RSW-Osc pin and the VDD supply pin, while the EL lamp driver frequency is set by an external resistor connected between the REL-Osc pin and the VDD pin. An external inductor is connected between the LX pin and the VDD pin, and a capacitor is connected between the CS pin and GND. The EL lamp is connected between the VA and VB pins.
This IC is suitable for applications such as handheld personal computers, electronic personal organizers, GPS units, pagers, cellular phones, and portable instrumentation. It is supplied in an 8-SOIC package and is designed for surface mount applications. The operating temperature range is -25°C to 85°C.
