Maxim Integrated MAX749CSA+T LCD Bias Supply

The MAX749CSA+T from Maxim Integrated is a specialized integrated circuit designed to provide a reliable and efficient bias supply for liquid crystal displays (LCDs). This compact and high-performance component is an ideal solution for portable devices where space is at a premium and power efficiency is paramount.

The MAX749CSA+T operates by converting a low-voltage input into a high-voltage output, suitable for driving the rows and columns of passive matrix LCDs. It is capable of providing a positive output voltage up to +28V from a +2.7V to +5.5V input, making it versatile for different LCD requirements. Additionally, the device features a low quiescent current of 300µA (typical) and a shutdown mode that reduces the supply current to 0.1µA (typical), which is essential for battery-operated equipment.

This component is designed with ease of use in mind, requiring minimal external components to function. The inclusion of an on-chip oscillator eliminates the need for an external frequency-setting resistor or capacitor, simplifying the design process. Furthermore, the MAX749CSA+T is equipped with a thermal shutdown mechanism that protects the device from overheating, enhancing its reliability and longevity.

Enclosed in a small 8-pin SOIC package, the MAX749CSA+T is a space-saving solution that can easily be integrated into various electronic designs. Its temperature range from 0°C to +70°C ensures stable performance across a wide range of environmental conditions.

Key applications for the MAX749CSA+T include portable instruments, handheld devices, laptop computers, and any other applications where an efficient and compact LCD bias supply is required. Maxim Integrated's commitment to quality means that designers can trust this component to provide a stable and long-lasting LCD bias solution for their products.

With its combination of high efficiency, low power consumption, and small footprint, the Maxim Integrated MAX749CSA+T stands out as a smart choice for powering the next generation of compact LCD displays.
