Specialized ICs

PQJ7981AHN/C0C,515 is an advanced integrated circuit (IC), which belongs to the broad category of Specialized ICs. This type of IC is unique as it is designed for specific tasks, instead of providing general functions like most of silicon chips. PQJ7981AHN/C0C,515 is a prime example of Specialized ICs, with its ability to provide what is called a “charge pump circuit” – a type of voltage converter. This voltage converter is designed to fulfill the need of certain devices demanding higher outputs than what their own power sources provide.

Application Fields

PQJ7981AHN/C0C,515 can be applied to a broad range of applications, such as powering sensors and meter indicators in consumer appliances, as well as medical devices and LCD polarity inversion drivers. In consumer electronics, PQJ7981AHN/C0C,515 can serve as a reliable and efficient power supply, providing the essential output needed. In medical equipment, PQJ7981AHN/C0C,515 can be put to work in facilitating the life-saving procedures of the device. In LCD drivers, PQJ7981AHN/C0C,515 can prove its worth in delivering signals with accuracy and consistency, providing the necessary power for a successful display.

Working Principle

At the core of PQJ7981AHN/C0C,515 is the charge pump circuit which enables the IC to produce the necessary output voltage. This charge pump circuit starts with a low voltage drop across two switches, preferable MOSFETs. As the switch is turned on and off repeatedly, the electric charge is stored in two buckets, the input voltage (Vin) and the output voltage (Vout). As the switches are toggled, the charge is pushed and pulled from one bucket to the other, making way for higher and higher output voltages, eventually reaching VC-max. The maximum voltage output from the IC is ensured by limiting the charge amount in each cycle, such that if the IC is overloaded, it will not be able to reach the maximum output voltage.

In addition to the charge pump circuit, PQJ7981AHN/C0C,515 also comes with tight tolerance of 0.V1 and an adjustable slew rate of (1 to20kHz). It has a wide operating range between 1.7V to 5.5V, making it perfectly suitable for applications with a broad range of input voltage. Furthermore, PQJ7981AHN/C0C,515 offers the best in class current leakage, measured at 30nA, making it ideal for low power applications with little or no noise produced.

The PQJ7981AHN/C0C,515 is a perfect example of a Specialized IC. Its combination of power, reliability and low voltage makes it suitable for many specialized applications, from consumer electronics to medical devices.
