Product overview
IR2101S 600V High-Side & Low-Side Gate Driver IC – SOIC-8
The IR2101S is a high-voltage, high-speed high-side and low-side gate driver IC designed to drive power MOSFETs and IGBTs in half-bridge and related power-switching circuits.
Originally developed by International Rectifier and now supported by Infineon, the IR2101S incorporates independent high-side and low-side referenced output channels and a floating high-side channel capable of operation up to 600V.

Important Package Information
The “S” suffix in IR2101S identifies the 8-lead SOIC surface-mount version. The related IR2101 is also available in an 8-lead PDIP package, so the package must be checked before ordering a replacement.
Replacement Information
When replacing an existing gate-driver IC, verify the complete IR2101S part number, SOIC-8 package, pin configuration, supply voltage and surrounding MOSFET/IGBT circuitry. The IR2101 and IR2102 families should not be treated as identical because their input/output logic behavior differs.
