Power semiconductors, such as transistors, are integrated into various systems to control the flow of electrical current. The IR2085S is a self-oscillating gate driver, which is used to increase the efficiency of power transistors. As a part of a PMIC (Power Management Integrated Circuit) device, the IR2085S can reduce system power consumption, lower EMI (Electro-Magnetic Interference) levels, and provide safety protection to enhance system reliability.

The IR2085S is an advanced, high-performance gate driver for MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors), IGBTs (Insulated-Gate Bipolar Transistors), and other power switching devices. It features a high-speed oscillator, precision current limit, and advanced fault protection, making it suitable for a wide range of applications such as power conversion, motor control, and automotive powertrain.

The IR2085S’s main advantage lies in its high-precision current limit design. This allows the device to operate at higher switching speeds with lower losses, as well as providing protection in the event of a short circuit or overload situation. The current limit is adjustable, allowing the user to fine-tune the device according to their specific needs.

The IR2085S is a logic- and voltage-controlled gate driver. It uses a CMOS- compatible logic input to determine when a device’s gate should receive a voltage pulse. A logic high signal triggers the oscillator and initiates a low-side MOSFET turn-on pulse, while a logic low signal triggers the oscillator and initiates a high-side MOSFET turn-off pulse. The IR2085S also supports standard and high-current options, with a maximum output current of 6A.

The working principle of the IR2085S is based on the Switch-Mode Oscillator (SMO). When the logic input is high, the SMO initiates an oscillation cycle to create a gate-drive pulse for the desired device, providing an adjustable gate-drive voltage. When the logic input is low, the oscillator is disabled, preventing any gate drive voltage from being generated. The gate-drive voltage generated by the SMO is adjustable for both the high-side and low-side MOSFETs by setting the external resistor values.

The IR2085S is an ideal device for power management applications. It can be used in a wide range of applications, such as electric vehicles, solar inverters, home appliances, consumer electronics, and power supplies. Additionally, the IR2085S supports a wide range of protection features, such as overvoltage protection, short-circuit protection, and current limiting.

In summary, the IR2085S gate driver is a powerful, high-performance device ideal for modern power management applications. It features a high-speed oscillator, adjustable current limit, and advanced fixed frequency fault protection, making it suitable for a wide range of design requirements. It is also a low-cost solution for systems looking to minimize power consumption and lower EMI levels.
