IR2125S Description

Short technical summary and product information.

The IR2125S from Infineon Technologies is a high voltage, high speed power MOSFET and IGBT driver. It is designed for high-side driving configurations and offers robust protection circuitry, including over-current limiting.

 

Key electrical specifications include a high-side floating offset voltage capability of up to 500V and a gate drive supply range of 12V to 18V. The device supports output currents of 1.6A and 3.3A, with typical turn-on and turn-off times of 150ns. Logic inputs are compatible with standard CMOS or LSTTL outputs down to 2.5V logic.

 

This gate driver IC is housed in a 16-SOIC package, suitable for surface mount applications. It operates within a junction temperature range of -40°C to 150°C. The IR2125S is designed to limit the current in the driven power transistor and provides an error lead to indicate fault conditions.

 

Features such as dV/dt immunity and undervoltage lockout contribute to its reliability in demanding power applications. The output is in phase with the input, simplifying circuit design.
