Power management integrated circuits (PMICs) are semiconductor devices with numerous voltage regulating, current monitoring and temperature measuring functions. They are utilized in modern consumer electronics, for example, mobile phones, laptops, and tablets. PMICs are regularly incorporated with microprocessors and other system-on-chip (SoC) components to provide the processor with clean, constant power. One class of PMICs is gate drivers, which are components used in power management and voltage translation that can control the power flow inside and between devices. EL7202CSZ-T13 is an example of a gate driver.

Applications

Gate drivers serve to drive the control and protection circuitry of power management systems by providing high-current, high-voltage pulses and low-voltage, high-frequency signal control. El7202CSZ-T13 is one of the latest gate drivers offered by integrated circuit providers. It is suggested for applications such as IGBT and power MOSFET drives, LEDs and ESD protection, signal conditioning, and other power switching applications. Additionally, EL7202CSZ-T13 gate drives are specifically designed for intelligent power switch (IPS) applications and for polymer-tantalum capacitor protection.

Features

EL7202CSZ-T13 has various features that make it suitable for a range of power applications. It has an integrated minimum on-resistance of 600 milli-ohms (mΩ) for half-bridge topologies, which is a desirable feature for high-power applications requiring a relatively low resistance. It also operates across a wide temperature range of -40°C to +85°C and over-temperature and over-current protection. It features direct driving of IGBTs and power MOSFETs, enabling power switch control up to 500kHz.

Fitted with an output 1A maximum peak current, EL7202CSZ-T13 gate drivers are ideal for switching impedances up to 15kΩ and gate-source capacitances up to 1μF. It supports programmable dead time and floating gate driver, and has an output signal with maximum rise time of 2μs. Furthermore, the gate drivers have temperature, current and voltage monitoring, along with ESD protection for integrated circuit protection.

Working Principle

Gate drivers allow the power switch control and protection circuitry within a power management system to communicate with each other and external components. EL7202CSZ-T13 gate drivers provide the necessary drive for power semiconductor gate control, providing gate voltage and current output. This is done by taking the gate voltage needed to turn on the selected power device from low to high and then reversing the process when turning it off.

For example, when an IGBT is in the off-state, EL7202CSZ-T13 refers to the gate voltage level needed to turn on the device. The gate driver then takes the gate voltage to the same level, supplying the necessary current to keep it on. The device can then be turned off by reversing the signals, meaning the gate voltage is reduced back to the value it was before the device was turned on. This process is known as "switching" the IGBT, and EL7202CSZ-T13 gate drivers are well suited for this applications thanks to their integrated low on-resistance, high-current pulses and low-voltage, high-frequency signal control.

Advantages

EL7202CSZ-T13 gate drivers provide numerous benefits for modern power management and voltage translation. They are specifically designed for use in intelligent power switch applications and have integrated protection features to protect against over-temperature and over-current. The wide temperature range of operation, direct driving of IGBTs and power MOSFETs, and the low-resistance integrated into the driver are all benefits that make this type of gate driver an excellent choice. Additionally, it has the ability to switch highly capacitive devices and longer cables with its fast rise time, making it even more beneficial for use in power applications.

Conclusion

EL7202CSZ-T13 gate drivers are a powerful and efficient way to control power and voltage translation within a power management system. They are designed specifically for applications such as IGBT and power MOSFET drives, LEDs and ESD protection, and signal conditioning, and provide several advantages over other types of gate drivers. Their integrated protection against over-temperature and over-current and direct driving of IGBTs and power MOSFETs make EL7202CSZ-T13 gate drivers a reliable and effective choice for any power management application.
