SP310EET-L is an integrated driver, which consists of a gate driver and a half bridge MOSFET driver. It is especially suitable for designs requiring high-speed switching and high withstand voltages. It has small size, low power consumption and very high power efficiency. It is widely used in the field of large power electronic devices.

SP310EET-L Applications

The SP310EET-L is ideal for any applications requiring high-speed switching of power, such as power factor controllers, high frequency inverters, high voltage DC supplies, and synchronous rectification/surge protection. The SP310EET-Lis also ideal for applications requiring precise inductive load triggering, such as piezo actuators, motor drivers, and active headlamps.

The SP310EET-L can also be used in applications that require high voltage isolation and noise suppression, such as active clamps for protection against EMI, or for digital control or timing of high voltage devices. In addition, it can be used for the conversion of digitally-controlled power sources and digital power conditioning.

SP310EET-L Working Principle

The SP310EET-L uses a half bridge MOSFET driver to achieve high-speed switching with minimal voltage drops. The driver consists of two half-bridge MOSFETs connected in series, which can be switched alternatively in order to create a high-speed switching circuit. The gate driver is used to control the switching of the MOSFETs, by driving the gates of the MOSFETs at different voltages depending on the desired speed. The driver also includes a delay circuit, which can be used to ensure the MOSFETs are switched at the right time.

The SP310EET-L also includes a protection circuit to prevent the MOSFETs from overcurrent and overvoltage damage. It includes a voltage-limiting current source, which will shut down the MOSFETs when the current reaches a certain value. It also includes a temperature-sensing circuit, which will shut down the MOSFETs if the temperature of the MOSFETs exceeds a certain value. This will protect both the MOSFETs and the driver from overcurrent or overvoltage damage.

Conclusion

The SP310EET-L is a very useful integrated driver for high-speed switching applications, especially those requiring precise inductive load triggering. It is a very efficient driver, with a small size and low power consumption, and it is especially suited for applications that require high voltage isolation and noise suppression. The protective circuit ensures the safety of the driver and the MOSFETs.
