The SN75374DR is a high-speed bidirectional universal switch driver. It is a product from Texas Instruments and is classified as a power management integrated circuit (PMIC) in the gate drivers category. This article will discuss the application field and working principle of the SN75374DR.

The SN75374DR is a highly efficient and cost-effective pre-driver IC for H bridge and bidirectional converters. It is designed to drive high efficiency motors, solenoids, and other inductive loads, with fantastic current capability up to 4A, compound with low power dissipation in both the high and low sides of the bridge. With monolithic circuitry, the SN75374DR is able to keep voltage drop to very minimum, which allows the design to save energy and even reduce board size. Furthermore, it is capable to provide a fast direction change with minimum noise, thanks to its wide output swing and differential triangular truncation control technology.

The SN75374DR is ideal for a variety of applications such as motor control, H bridge driver, and amplifier/inverter drive. It has the same pin and footprint with its predecessor, the SN75373DR, which provides an easier route for the design to upgrade from SN75373DR to SN75374DR. Ultimately, the SN75374DR is a powerful and suitable solution for switch driving applications with comparable and more improved performance compared to traditional circuit designs.

The SN75374DR is a TTL compatible, monolithic integrated circuit with two bidirectional switches. It can drive inductive loads of up to 4A at peak current and operates from 4.5V to 24V. Moreover, it comes with a logic enable/disable control pin to ensure correct enable/disable functions in a simplified manner. In addition, SN75374DR is protected against a wide range of current and temperature changes, making it deniable to short-circuit damage, thermally-induced stress, and other hazards during its application.

The SN75374DR works with a power pin and an enable pin. When the enable pin is in the working state, the power pin is activated and will supply current to the bridge when it is reversed. The power pin also provides feedback control so that the switches can be synchronized with the direction of the current shifting. An internal oscillator is used to set the switching frequency and ensure accurate operation. Furthermore, the SN75374DR has open-collector outputs that allow for safe and easy interfacing with microcontrollers.

In conclusion, the SN75374DR is a powerful gate driver for switching applications. It comes with accurate and reliable performance, monolithic circuitry, widevoltage range, and superior current capability all in a small package. Its excellent features make it ideal for applications such as motor control, H bridge driver, and amplifier/inverter drive. Additionally, SN75374DR is protected from most current and temperature changes, making it suitable for long-term usage. Last but not least, the SN75374DR is user-friendly with its enable/disable control logic and open-collector outputs.
