Power management integrated circuits (PMICs) are an integral part of modern electronic devices. They provide power supply control, power monitoring, and power conversion in a single integrated circuit. Gate drivers are an important component of a PMIC, and they enable efficient and reliable control of power switches in power management applications. The EL7202CN is a two-channel, integrated high-voltage, high-side gate driver designed for automotive applications.

The EL7202CN integrates two independent high-voltage, high-side drivers with a common low side driver for automotive applications. The outputs of the high-side drivers can be connected in parallel to drive large loads. Each driver channel has its own enable pin, supply voltage monitor and output enable logic with adjustable dead time, over-temperature protection, and current sense amplifier capability.

The application field of EL7202CN includes switch mode power supplies (SMPS) for automotive applications such as light dimming, active braking, power conversion, and control of low voltage power sources. It can also be used in automotive battery management, fuel injection, and DC/DC conversion applications. The device’s programmable dead-time circuitry allows it to work in different systems with varying requirements. Its integrated over-temperature protection and current-sense amplifier capability ensure reliable circuit performance.

The EL7202CN supports a wide range of input voltage options (7V to 42V) and has a wide range of output voltage options (up to 400V). It also supports switching speeds up to 1MHz and has an adjustable dead time to reduce electromagnetic interference (EMI). The device also has protection features such as overcurrent, short-circuit, over-temperature, and over-voltage protection.

The EL7202CN works by using a pulse width modulation (PWM) technique. It uses an on/off signal to control the voltage output of an integrated high-voltage switch. The high-voltage switch is connected to the low-side driver and the high-side drivers. When the PWM signal is low, the integrated high-voltage switch is off, and the low-side driver and high-side drivers are inactive. When the PWM signal is high, the switch is on and the low-side driver and high-side drivers are active. The PWM signal can be used to control the voltage output of the system.

The EL7202CN gate driver is a versatile and reliable device for automotive applications. It can provide reliable control of multiple outputs with a single chip and has adjustable dead-time circuitry, over-temperature protection, and current-sense amplifier capability. It also supports a wide range of input and output voltages and a wide range of switching speeds. It is an ideal solution for automotive applications, as it is reliable and easy to implement.
