Power Management Integrated Circuits (PMICs) are a key component in multiple electronic applications. PMICs are integrated circuits that include functions such as power conversion, power sequencing, voltage and current regulation, and gate driving. The LM2722MX/NOPB is an example of a PMIC that serves as a Gate Driver. In this article, we will cover the application field and working principle of LM2722MX/NOPB.

LM2722MX/NOPB is a specialized PMIC intended primarily for application in the automotive industry. It is a gate driver IC that features a high switching frequency and high accuracy for the automotive industry. It provides high-output current drive capability and integrated protection against short circuits, overvoltage, and under-voltage. With its cost-effective and higher efficiency, this gate driver IC is ideal for automotive applications such as power seats, wiper control, windshield defrosters, power window control, and headlight control.

When it comes to the working principle, the LM2722MX/NOPB is designed for driving low side and high side power MOSFETs, IGBTs, and high brightness LED (HBLED) applications. It operates in a single stage ground-referenced circuit, using the commonly known “flyback” method. This gate driver has power input and output circuits which are independent. The power output consists of two outputs, four switch connections, and two pulse current control inputs. When triggered, the two outputs convert the primary voltage into a high voltage, which then drives the switching devices. This high voltage is the source of power for the HBLED. The LM2722MX/NOPB also has an integrated protection against short-circuit, over-voltage, and under-voltage, which maximizes performance and safety.

In summary, the LM2722MX/NOPB is a reliable gate driver IC specially designed for automotive applications. It features a high switching frequency, high accuracy, and low cost — all of which ensure maximum performance and safety in such applications as power seats, wiper control, and windshield defrosters. The working principle of LM2722MX/NOPB includes two power input and output circuits, four switch connections, and two pulse current control inputs that convert the primary voltage into a high voltage, which then drives the switching devices.
