It integrates two independent, non-inverting driver channels in an 8-SOIC package. The high-side driver is referenced to a bootstrap supply rated to 600 V maximum, allowing the part to drive the top transistor in a half-bridge leg directly from a low-voltage supply rail. ## Output current and switching speed Peak output current is specified at 1.9 A source and 2.3 A sink, which provides the gate charge needed to switch medium-power MOSFETs and IGBTs in the 10–100 kHz range without excessive crossover conduction. This switching speed keeps dead-time margins tight; the downstream power stage must be matched to the driver's timing to avoid shoot-through. ## Supply range and logic interface The supply voltage range of 10 V to 20 V covers the typical bias rails for industrial gate drive — 12 V and 15 V are the common operating points. The undervoltage lockout thresholds are set within this window to ensure the driver does not turn on the power stage below the gate threshold. ## Temperature grade and package Rated for operation from -40°C to 150°C junction temperature, the IR2181STRPBF covers industrial and automotive ambient conditions. The 150°C TJ ceiling allows the driver to sit close to the power stage without derating the output current. The narrow-body SOIC footprint is a standard layout for low-to-medium pin-count gate drivers. ## Production status and compliance The part is ROHS3 compliant, meeting the latest restriction-of-hazardous-substances directive for lead-free assembly.","metaTitle":"IR2181STRPBF Infineon Half-Bridge Gate Driver, 600V, 8-SOIC","metaDescription":"IR2181STRPBF half-bridge gate driver from Infineon, 600V bootstrap, 1.9A/2.3A peak output, 8-SOIC.
