IRS2186STRPBF Overview
The IRS2186STRPBF is a high-performance gate driver from Infineon, designed for the efficient driving of MOSFETs and IGBTs. It uses proprietary High-Voltage Integrated Circuit (HVIC) and latch-immune CMOS technology, supporting independent high and low-side driving, and can operate stably in environments up to 600V. This device is suitable for direct use with standard control circuits.
In terms of performance, the IRS2186STRPBF provides a 4A source and sink current output, meeting the demand for fast switching and low power loss in single-phase circuits. Packaged in an 8-pin SOIC that supports surface mount (SMD/SMT), it saves circuit space and is easy to integrate into modern power designs. This makes the device widely valuable for applications in power electronics, industrial drives, and inverters.

IRS2186STRPBF Block Diagram
Based on the functional block diagram of the IRS2186STRPBF, the chip integrates two independent driver channels: one for the high side and one for the low side. The high-side driver uses a High-Voltage Level Shifter to transfer the input signal from a logic level to the high-voltage side. This signal is then modulated and optimized by a Pulse Generator and a Pulse Filter before finally driving the HO output. The high side also includes Undervoltage Lockout (UVLO) detection and a latch circuit to ensure the device shuts down promptly in the event of a low power supply voltage, preventing the power device from operating abnormally.
The low-side driver consists of a level shifter, a Delay unit, and logic gates. It receives the LIN input and drives the LO port output. This section also integrates an undervoltage detection module to ensure the driver is disabled during low-power conditions. The low-side design is simple and efficient, and together with the high-side driver, it can handle the driving needs of complete half-bridge or full-bridge topologies. Overall, the IRS2186STRPBF provides a stable gate driving capability through the combined operation of its high and low-side drivers, making it suitable for high-voltage, high-speed MOSFET and IGBT applications.
