Maxim Integrated MAX868EUB+T Charge Pump Voltage Inverter

The MAX868EUB+T is a high-efficiency charge pump voltage inverter produced by Maxim Integrated, a renowned manufacturer of analog and mixed-signal integrated circuits. This compact and versatile component is designed to provide a simple and effective solution for applications requiring a negative voltage rail generated from a positive input voltage.

With its capability to invert input voltages ranging from +1.5V to +5.5V, the MAX868EUB+T is an ideal choice for a variety of portable and battery-powered devices. The output voltage is equal to the negative of the input voltage, making it perfect for systems that need a dual supply from a single positive source.

The device comes in a tiny, space-saving 10-pin µMAX package, which is highly beneficial for space-constrained applications. It is also available in tape and reel packaging, denoted by the '+T' suffix, making it suitable for automated assembly processes.

One of the key features of the MAX868EUB+T is its high efficiency, which is achieved through a regulated charge pump that operates at 12kHz or 35kHz selectable switching frequencies. This allows for the use of small, low-cost capacitors while minimizing ripple voltage and noise, thereby ensuring a clean and stable negative output voltage.

Additional features include a low quiescent current, which helps to prolong battery life in portable devices, and a thermal shutdown mechanism that provides protection against overheating. The device also offers a 'shutdown' pin that can be used to disable the charge pump, reducing the quiescent current to a mere 1µA (typical) during standby mode, which is crucial for power-sensitive applications.

In summary, the Maxim Integrated MAX868EUB+T is a reliable and efficient solution for generating a negative voltage rail in a variety of electronic systems. Its high efficiency, compact form factor, and additional features make it an excellent choice for designers looking to optimize power management in their products.
