GIB2404HE3/45

Diodes - Rectifiers - Arrays

The GIB2404HE3/45 is a high-pass filter rectifier array, integrated within a dual in-line package. It is suitable for a variety of applications including automotive, audio, and other consumer applications. This device offers multiple benefits, including improved electrical and thermal performance, an integrated low-pass filter, and an integrated open-drain output stage.

Application Field and Working Principle

The GIB2404HE3/45 is used in applications where high frequency signals need to be filtered, such as speakers, motor control, and jet engine control systems. It features two independent rectifier channels for flexibility in signal conditioning and integration of additional filter stages. The filter is designed to filter out signals higher in frequency than the filter\'s cut-off frequency, allowing lower-frequency signals to pass through. The filter is based on the principle of a low-pass filter, which is a type of RC filter (resistor-capacitor filter). In this filter, a resistive and a capacitive element are connected in series, and the output is taken after the connection. A low-pass filter absorbs high frequencies and passes low frequencies, so signals above the cut-off frequency (known as the 3 dB point) are greatly attenuated and signals below the 3 dB point are passed almost unaffected.

The GIB2404HE3/45 is specifically designed for automotive and power control applications. It features two channels with a two-stage filter, each with low-pass and high-pass filtering. The low-pass filter is designed to reject unwanted signals of higher frequencies, while the high-pass filter allows signals of lower frequencies to pass through. The filter stage has a 3 dB point of around 25 kHz, making it suitable for high frequency applications. The open-drain output stage provided also provides current-limiting and soft-drive functions.

The GIB2404HE3/45 is ideal for applications where high frequency signals must be filtered, and its small package size makes it suitable for use in compact designs. The integrated filter, low-pass filter stage, and open-drain output make it an excellent choice for automotive and power control applications.
