Power semiconductor products play an irreplaceable role in many electronic systems. However, before these products can work, they all need the drive power, which is the gate driver. Gate drivers can convert the low-voltage control signals of the microprocessor into high-voltage signals to drive the gates of the power devices. They also protect the power devices from overvoltage, overcurrent, and ESD, thereby extending their life. As part of the power management integrated circuit (PMIC), gate drivers are important components of the system.

The LM25101ASD-1/NOPB is a high-speed, low-power, integrated gate driver for a wide range of power switches. It is designed for synchronous rectification MOSFETs (SRM) , IGBTs (IGBTs) , GaN FETs(GaN), and power-related thyristors (SCRs). The discharge of the gate includes a low-impedance gate drive, intrinsic gate clamp, and gate pull-down resistor.

The LM25101ASD-1/NOPB is a complete power system solution, including the low-voltage part, gate drive circuit, gate discharge resistance, signal isolation circuit, ESD protection circuit and other components. It can support the application circuit of voltage range 4V-18V. It has excellent performance and functions including advanced fault protection, programmable undervoltage lockout (UVLO) , programmable overcurrent protection (OCP) , etc.

The LM25101ASD-1/NOPB has two short-circuit protection functions. The first one is Internal Short-circuit protection (ISC) that limits the peak current when an overheated device leads to an internal short circuit. The second protection function is External Short-circuit protection (ESC) which is based on the variable switch On Time. It applies to the external MOSFET in the circuit and can also reduce the risk of short-circuit caused by the open cell.

In addition to protection circuits, the LM25101ASD-1/NOPB also has many practical features, such as the programmable power-up delay and turn-on / turn-off delay. The startup and shutdown sequence of the power device can also be programmed to ensure that the power device starts up and shuts down correctly. The OTW pin is also available for the addition of a thermal shutdown circuit. All of these features make the LM25101ASD-1/NOPB a versatile, high performance gate driver.

The LM25101ASD-1/NOPB is also an energy-saving gate driver. It uses a wide voltage range and low voltage reduction strategy, which can reduce the total power consumption of the system. In addition to saving power, it also supports a wide range of operating temperature (up to 150℃) and ESD protection (up to 3.3KV).

In conclusion, the LM25101ASD-1/NOPB gate driver is an ideal choice for power semiconductor applications. It can protect the power device from overvoltage, overcurrent, and ESD and provide a high-performance, energy-efficient way to drive power devices. This makes it an ideal choice for a wide range of power management applications.
