I. Product Overview

IR2181SPBF is a gate driver designed for high-voltage and high-speed drive requirements. With its wide voltage range, strong anti-interference ability, perfect protection function and Infineon’s brand support, it has a wide range of applications in motor control, power management, industrial equipment and other fields. Its balance of performance and cost makes it an ideal choice for engineers in complex circuit design.

1. Supports high-voltage side floating voltage up to 600V, suitable for high-voltage environments.
2. The gate drive power supply voltage range is 10V to 20V, compatible with standard CMOS or LSTTL logic input (minimum compatible with 3.3V logic).
3. Output current: Source 1.4A, Sink 1.8A, can drive high-power switching devices.
4. dV/dt immunity: Tolerant to negative transient voltage, enhance system stability.
5. Dual-channel undervoltage lockout (UVLO): Automatically shut down the output when the power supply voltage is below the threshold to prevent device damage.
6. Logic and power ground bias: support ±5V offset to improve noise immunity.
7. Turn-on propagation delay of 180ns, turn-off propagation delay of 220ns, matched delays ensure synchronization of high and low side channels.
8. Operating temperature range of -40°C to 125°C, adaptable to harsh environments.
9. Adopt SOIC-8 surface mount package to save circuit board space.

Applications:
1. Motor control and drive: motor control in industrial motor drives, robots, and household appliances (such as refrigerators and air conditioning compressors). High-voltage drive scenarios such as power tools and automotive power optimizers.
2. Power management: high-efficiency power conversion applications such as uninterruptible power supplies (UPS), power adapters, and industrial power conversion.
3. Welding and heating equipment: driving high-power switching devices in industrial heating and welding equipment.
4. Automotive electronics: scenarios that require high-voltage drive, such as power tools and automotive power modules.
