Specialized ICs

The DS34S104GN is an application specific integrated circuit (ASIC) used to provide manufacturers with a high performance automotive-grade solution. It is designed for use in conditions found in the automotive industry, such as high temperature, low voltage, and high reliability. This device is an ideal solution for automotive applications, including powertrain and chassis applications, telematics, infotainment systems, and advanced driver assistance systems (ADAS) amongst others.

The DS34S104GN integrates a 3.3V voltage regulator with an over current protection circuit, a reset signal output, a power-on-reset circuit, and a power-fail signal output. It is available in a small serial-type package, making it ideal for use in space constrained applications. The ASIC also has a built in temperature compensation circuit that can actively adjust the levels of output voltages.

Application Field

The DS34S104GN has a wide range of applicability in the automotive industry. It is suitable for use in powertrain and chassis applications, such as engine control, fuel injection systems and vehicle stability control, telematics, infotainment systems, and advanced driver assistance systems (ADAS), amongst others. The ASIC is designed to operate in high temperature, low voltage, and high reliability conditions, making it an ideal choice for these applications.

Working Principle

The DS34S104GN effectively combines a 3.3V voltage regulator circuit and an over current protection circuit into a single integrated circuit. The ASIC includes an input voltage protection circuit, a power-on-reset circuit, a power-fail signal, and a temperature compensation circuit. The ASIC automatically adjusts the level of output voltage in relation to the temperature. The ASIC also features short circuit protection, high power efficiency, and low shut-down current.

The 3.3V voltage regulator circuit is designed to regulate an input voltage of 4.5V-5.5V down to a safe and consistent 3.3V output. This allows for low power and high performance power distribution applications. The over current protection circuit functions by detecting any over current levels in the system, and then sending a signal to the power supply or system driver IC to shut down the system, thereby preventing any further damage to the system components.

The reset signal output provides a reset signal in order to reboot the system. The Power-on-reset circuit helps to detect and reset the system in case of abnormal power conditions. The power-fail signal helps to determine when the system is transferring from one power state to another.

The DS34S104GN is further equipped with a temperature compensation circuit which actively adjusts the level of output voltage in relation to the temperature. This allows the ASIC to operate efficiently and reliably in temperatures up to 125°C. The ASIC is designed to meet the automotive requirements of high temperature, low voltage, and high reliability.

The DS34S104GN is an ideal solution for automotive applications where a combination of high performance and reliability are necessary. It is designed to integrate the functions of a 3.3V voltage regulator, an over current protection circuit, a reset signal output, a power-on-reset circuit, and a power-fail signal into a single integrated circuit.
