The LM2722M/NOPB is a Gate Driver from Texas Instruments’ Power Management and Interface (PMIC) family. It is a single-channel, low-side driver with a fixed 1.4 A limit and 0.7 A current-sense threshold that supports load currents up to 3 A. This integrated circuit is designed to drive two N-channel MOSFETs, making it a suitable solution for low-side power supply applications, such as batteries, portable devices, point-of-loads (POLs) and LED drivers.     

The LM2722M/NOPB is a low-side driver with a fixed 1.4 A current limit and 0.7 A current-sense threshold, which provides increased protection in the event of an overload. It also features a low-voltage supply of 2.8 V, allowing for more flexibility in design and providing higher efficiency. The LM2722M/NOPB can be used to drive two N-channel MOSFETs in paralel for a maximum load current of 3 A. It is also available in a QFN 3 × 3 mm package for space-constrained applications.

The LM2722M/NOPB has a robust thermal shutdown protection, with an over-temperature threshold of 165 °C, and is able to withstand a maximum junction temperature of 175 °C. Additionally, it has undervoltage and overvoltage protection. Standard safety certifications are also available, including UL Recognition, AEC-Q100 and IEC/EN/UL 60950.

The LM2722M/NOPB is designed to drive two N-channel MOSFETs in parallel, providing a maximum load current of 3 A. It has a low-side gate driver with a fixed 1.4 A current limit and 0.7 A current-sense threshold. It is capable of driving both low-side and high-side devices when used with an isolated gate driver. The gate driver features an adjustable firing circuit and synchronous rectification. Furthermore, it has a built-in fault detection, featuring an adjustable threshold that sets the shutdown voltage.

The principle of the operation of the LM2722M/NOPB can be seen as a combination of mechanical and electrical components. The mechanical component is a mechanical device in the form of a switch, which is triggered into action when a certain voltage is applied to it. The electrical component is a driver circuit, which is a component that controls the current that flows through the switch. In this case, the voltage is applied to the gate of the transistor in order to trigger the action of the switch. The driver circuit then controls the current that is allowed to flow through the switch in order to control the state of the switch.
