AUIRS21814STR Description

Short technical summary and product information.

The Infineon Technologies AUIRS21814STR is a high voltage, high speed power MOSFET and IGBT driver. It offers independent high and low-side referenced output channels, designed for bootstrap operation and fully operational up to 600 V. The device is tolerant to negative transient voltage and dV/dt immune.

 

Key electrical characteristics include a gate drive supply range of 10 V to 20 V, with output source and sink current capabilities of 1.9 A and 2.3 A, respectively. Turn-on and turn-off delay times are typically 160 ns and 200 ns. The logic input is compatible with 3.3 V and 5 V logic levels.

 

This gate driver is suitable for applications such as Piezo/common rail Injection, Starter/Alternator, Electric Power Steering, and Fan and compressor systems. It comes in a 14-SOIC package and supports surface mount.

 

The AUIRS21814STR operates within a temperature range of -40°C to 150°C (TJ). It is RoHS3 compliant and has an MSL rating of 1.
