EL7222CSZ is a dual MOSFET driver. It belongs to Power Management IC (PMIC) - Gate Drivers family. This device is designed to drive high current, low voltage MOSFETs in synchronous buck converters. The EL7222CSZ is an integrated IC designed to drive two low side and two high side MOSFETs, so that it is much simpler to construct a synchronous buck converter. The IC offers very high peak output current capability, low supply current and wide operating temperature range. Therefore, this device is suitable for many applications where the synchronous buck converter is of utmost importance.

Application Field and Working Principle

The EL7222CSZ is suitable for applications such as automotive, industrial, medical, and power supplies. It has a wide operating temperature range, so it can also be used in a variety of extreme conditions. It is suitable for driving both high side and low side MOSFETs, or both from the same VDD supply, with a low supply current of 15mA. It also supports the widest range of operating voltages from 4.5V to 20V. Therefore, the EL7222CSZ is a perfect fit for automotive circuits, such as power steering, seatbelts and roof-mount ECUs.

In addition, the EL7222CSZ has a low quiescent current (15 mA). This is important as it keeps the total power consumption of the system low. Furthermore, this device can drive MOSFETs with a wide range of switching frequencies, making it very suitable for power supplies. Finally, this device has an integrated dead-time generator which prevents shoot-through current, making a synchronous buck converter more reliable and durable.

The EL7222CSZ has an operating principle that is similar to those of other gate drivers. It consists of two MOSFET drivers connected in parallel and each driver having two MOSFETs in series. This means that each driver can provide a peak output current of 2A and have a total peak output current of 4A. The driver also has a dedicated low-side driver, along with a dead-time generator, offering a synchronized switching between the high-side and low-side MOSFETs, which is important in preventing shoot-through current.

The EL7222CSZ also has various protection features such as over-temperature protection and under-voltage lock out (UVLO). Furthermore, it supports a wide operating voltage range and offers low EMI/EMC levels. The device has also been designed to work with a variety of different types of MOSFETs, and can be used with either N or P channel devices. This makes the device very versatile and suitable for a range of different applications.

Conclusion

The EL7222CSZ is a dual MOSFET driver from the PMIC - Gate Drivers family. It is suitable for a variety of applications and offers a wide operating temperature range, along with a low quiescent current of 15mA. This driver has a typical peak output current of 4A and features both a low side and high side driver, along with a dedicated dead-time generator. Furthermore, it supports a wide voltage range, provides an over-temperature protection, and offers low EMI/EMC levels. All these features make the EL7222CSZ a great choice when design a synchronous buck converter.
