Infineon IR2181SPBF MOSFET Driver, High/Low Side, SOIC-8
High-voltage MOSFET/IGBT driver, SOIC-8, surface mount. 600V high-side capability, 10-20V supply, robust performance.
The Infineon IR2181SPBF is a high-voltage, high-speed power MOSFET and IGBT driver with independent high and low-side referenced output channels. Its proprietary HVIC and latch-immune CMOS technology ensures ruggedized monolithic construction, making it a reliable choice for demanding power management applications.
This driver features a high pulse current buffer stage designed to minimise driver cross-conduction. The floating channel can drive an N-channel power MOSFET or IGBT in a high-side configuration, operating up to 600V. It is compatible with standard CMOS or LSTTL outputs, down to 3.3V logic, ensuring flexible integration with various control circuits.
Key Features:
- Tolerant to negative transient voltages and DV/DT immune for enhanced robustness.
- Under-voltage lockout for both channels ensures safe operation.
- Matched propagation delays for both channels.
- Lower DI/DT gate driver for improved noise immunity.
- Logic and power ground ±5V offset capability.
