AUIR3241STR Description

Short technical summary and product information.

The Infineon Technologies AUIR3241STR is a high-side MOSFET gate driver suitable for back-to-back switch applications. It offers very low quiescent current in both on and off states, making it energy-efficient.

 

This device operates within a wide voltage range of 3V to 36V and is compatible with 3.3V logic inputs. It features under-voltage lockout protection to prevent the MOSFET from operating in linear mode. The AUIR3241STR drives standard level MOSFETs, even at low battery voltages.

 

Packaged in an 8-SOIC surface-mount package, the AUIR3241STR has an operating temperature range of -40°C to 150°C (TJ). It is designed for applications such as power switches for Stop and Start systems and battery switches.

 

Key electrical specifications include an output current of 350mA, rise and fall times of 6µs, and low quiescent currents of 35µA (off) and 45µA (on) at 25°C.
