Product Overview
The IRS2103STRPBF is a 600V high-side and low-side gate driver IC from Infineon Technologies. Housed in a SOIC-8N package, this half-bridge driver features independent high and low side outputs with integrated dead-time generation. Based on Infineon’s proprietary HVIC technology, the IRS2103 provides robust operation with high noise immunity and dV/dt tolerance. The device accepts a single PWM input and generates complementary high-side and low-side gate drive signals with built-in dead time, eliminating the need for external dead-time generation circuitry. Undervoltage lockout protection is provided for both channels to ensure reliable operation under all supply conditions.
