Power management integrated circuits, also known as PMIC, are a type of integrated circuit designed to monitor, manage and optimize electrical power consumption in various applications. Gate drivers are a type of peripheral equipment specifically designed for managing signals, improving signal isolation and galvanic isolation. The EL7202CS-T7 is a Power Management Interface Circuit (PMIC) for controlling the gate of a Power MOSFET. This article will discuss the application field and working principle of the EL7202CS-T7.

Application

EL7202CS-T7 is a System-on-Chip (SoC) solution primarily designed for switching applications, particularly those involving power MOSFETs. This PMIC is ideal for applications such as power management, motor control, and motor switching. In addition, the device is also capable of driving the gate of both low- and high-side MOSFETs in a synchronous boost or buck mode, which increases power efficiency and reduces power losses. The EL7202CS-T7 also features a low quiescent current and reverse battery protection, making it suitable for battery-powered applications.

The device is available in a small 6-pin SOIC package, making it easy to mount, and is rated for a maximum junction temperature of 130°C. This makes it more durable and reliable in both commercial and industrial applications. The EL7202CS-T7 also supports both TTL and CMOS logic inputs, making it an ideal choice for applications that require both digital and analog solutions.

Working Principle

The EL7202CS-T7 consists of two separate high and low side power MOSFETs, both of which can be individually enabled, disabled and pulsed. When a logic signal is applied to the enable pin, the device switches on and the external capacitor connected to the high-side is then charged. Meanwhile, the low-side MOSFET is off, ensuring that the load does not draw any current. When the enable signal is removed, the high-side MOSFET is off, allowing the voltage to be discharged through the load.

The device is designed with a range of features to ensure safe and efficient operation. The device features short circuit protection, over-temperature protection, thermal shutdown and under voltage lock-out (UVLO) for the high-side and low-side MOSFETs. For added safety and reliability, the EL7202CS-T7 also includes over-voltage protection and reverse battery protection capabilities.

The EL7202CS-T7 is also equipped with a slew rate control switch, which allows the user to adjust the rise and fall times of the output voltage waveform. This provides the user with more flexibility when it comes to controlling the switching frequency and voltage slew rate of the output waveform. In addition, the device is also equipped with built-in fault monitoring circuitry that can detect and report any faults or errors.

The EL7202CS-T7 is an advanced Power Management Interface Circuit (PMIC) designed for controlling the gate of a Power MOSFET. This device is designed for use in applications such as power management, motor control, and motor switching. It features a range of safety and efficiency features, including short circuit protection, over-temperature protection, thermal shutdown, under-voltage lock-out, over-voltage protection and reverse battery protection. The device is available in a small 6-pin SOIC package, making it easy to mount, and is rated for a maximum junction temperature of 130°C.
