DGD2190S8-13

Power management integrated circuits (PMIC) are used to manage the power of a system and ensure that it operates efficiently at all times. Gate drivers, a type of PMIC, are designed to drive the electrical signals necessary for switching power electronic switches. DGD2190S8-13 is an example of such a gate driver.

The DGD2190S8-13 is a dual-channel gate driver designed to drive low-side MOSFETs or IGBTs with a maximum source current of 0.35A. It offers high-side and low-side drivers with integrated level shift circuitry. The output voltage level can be modified externally with an optional resistor. The device also includes an adjustable overcurrent detector providing additional protection.

The DGD2190S8-13 provides a wide range of applications. It works in motor control applications where it drives motors with large load changes. It is also designed for high-speed power supplies and industrial server applications. In automotive applications, it is suitable for use in DC-DC converters, power steering systems and electric power assisted steering systems.

The DGD2190S8-13 has a working principle based on voltage level shifting. It features an input/output voltage level shifting circuit which allows a high-side/low-side level shifter to be used in order to minimize power losses. As the input voltage is increased, the output voltage is increased as well. This level shifter also reduces the number of components required, making the design simpler, smaller, and cheaper.

The device also includes an integrated overcurrent detection circuit which, when enabled, will periodically measure the gate driver output current and compare it with an adjustable threshold. If the current exceeds the threshold, the gate driver will shut off, protecting any connected power switches.

The DGD2190S8-13 is an advanced gate driver and is suitable for a wide range of applications. Its integrated voltage level shifter minimizes power losses while its integrated overcurrent detector provides additional protection. This makes it an ideal choice for driving low-side MOSFETs or IGBTs in motor control, high-speed power supplies, and automotive applications.
