MP1907AGQ-P Application Field And Working Principle

PMIC - Gate Driver technology has been around for decades but is currently experiencing a boom in usage due to its wide range of advantages and capabilities. So, what exactly is a PMIC-Gate Driver? How does it work? And what is the MP1907AGQ-P application field and working principle? This article will answer all of your questions.

A PMIC-Gate Driver is a type of integrated circuit (IC) that is used to control the speed and signal level of high frequency pulses. The gate drivers serve as the interface between the signal source, (usually a transistor), and the high-speed integrated circuits (ICs) that need the signal. It boosts the current, voltage and slew rate of the pulse signal, allowing the IC to switch faster than it would otherwise be able to without the driver.

The MP1907AGQ-P from solid-state device manufacturer Monolithic Power Systems is designed as an ultra-fast gate driver that is capable of driving large external MOSFETs and IPMs in extremely fast switching systems. It is specifically designed to handle short rise times, fast fall times and high-currents.

The MP1907AGQ-P is a dual-channel gate driver with an integrated low-side MOSFET. It features two separate high-side gate drive channels and one integrated low-side channel. The high-side output can be configured to boost the voltage to levels sufficient enough to drive large external MOSFETs or IPMS, without the need for additional charge pumps.

Its low-side output can be configured as a grounded source stage to drive the low-side MOSFET directly, or as a push-pull stage for driving both high-side and low-side devices. The MP1907AGQ-P gate driver also comes with the Protection and Diagnostic functionalities for low-side gate driving to ensure maximum system reliability.

The working mechanism of the MP1907AGQ-P gate driver is based on a special combination of power MOSFETs and insulated-gate bipolar transistors (IGBTs) designed to provide extremely fast switching frequencies. This combination allows it to handle short rise times, fast fall times and enable very high-currents.

The two high-side channels are driven by two MOSFETs or IGBTs. The high-side channel is designed to drive large external MOSFETs and IPMS, while the low-side channel is designed to drive the low-side MOSFET directly or as a push-pull stage.

The MP1907AGQ-P gate driver is primarily used in applications such as automotive powertrain, high-voltage DC-DC converters, server and telecom power supplies, AC motor drives, and white goods. It is also used in semi-custom and custom power converters and power supplies.

In conclusion, the MP1907AGQ-P from Monolithic Power Systems is a specialized dual-channel gate driver integrated with a low-side MOSFET. It is optimized for fast switching applications requiring short rise times, fast fall times and high-currents. It is a great choice for automotive, server and telecom
