SN75452BPSRG4

The SN75452BPSRG4 is a high voltage, high-current dual full-bridge gate driver designed for high power applications such as motor control, power supplies and other related power applications. It has a high operating temperature range and a wide operating voltage range of 12V to 30V. The SN75452BPSRG4 is typically used in motor drivers, servo drives and power conditioning applications.

The SN75452BPSRG4 effectively operates at both low and high frequencies. It uses an output stage that can switch between two full-bridge configurations, allowing it to drive medium power loads from its input. The driver incorporates a logic input that is used with standard logic systems to control the driver. It also features an active output short circuit protection to ensure high reliability and quality performance. Furthermore, the SN75452BPSRG4 is fitted with a thermal shutdown circuit to protect the device from thermal overload.

The working principle of the SN75452BPSRG4 is based on the dual full-bridge gate driver configuration. In this configuration, two half-bridge transistors are connected in parallel. Each half-bridge has four transistors, two n-channel and two p-channel, connected in a full-bridge configuration. The inputs to the driver are the logic inputs and the enable and disable inputs. The logic inputs control the switching of the two half-bridges, while the enable and disable inputs enable or disable the driver.

The driver will operate with logic inputs from either a TTL system or an open-drain logic system. The outputs from the driver are the two full-bridges. Each bridge has one high side and one low side transistor. These are controlled by the logic inputs, allowing the driver to switch both high and low side transistors in either direction. The output of the driver is connected to the load, which is either a DC motor or other medium power load. The SN75452BPSRG4 provides a current capacity up to 8A per bridge with a maximum analog transmission rate of 2A.

The SN75452BPSRG4 is a versatile gate driver that can be used in a variety of applications. It is particularly suitable for motor control, power supplies, and power conditioning applications. Its wide supply voltage range of 12V to 30V makes it suitable for a variety of applications. Its active output short circuit protection and thermal shutdown safety features make it highly reliable. Finally, its dual full bridge gate driver configuration allows it to efficiently drive both high and low side transistors in either direction.
