The AUIR3241STR is a high-side MOSFET driver designed for back-to-back switch applications. It operates within a voltage range of 3-36V and features very low quiescent current in both on and off states, making it suitable for power management in battery-operated devices. The driver includes a boost converter with an integrated diode, allowing it to drive standard level MOSFETs even at low battery voltages. It is compatible with 3.3V logic levels and incorporates under-voltage lockout protection to prevent operation in linear mode. The device is packaged in a SOIC8 format and is compliant with RoHS standards, ensuring it meets environmental regulations. Applications include battery switches and power management for automotive systems.
The AUIR3241S is a high side Mosfet driver for back to back topology targeting back to back switch. It features a very low quiescent current both on and off state. The AUIR3241S is a combination of a boost DC/DC converter using an external inductor and a gate driver. It drives standard level Mosfet even at low battery voltage. The input controls the gate voltage. The AUIR3241S integrates an under voltage lock out protection to prevent to drive the Mosfet in linear mode.
AUIRS3241S and AUIR3242S are basically identical, only difference is the operating level of the input pin. For instance, due to the active low level of input the AUIR3242S makes relay replacement very easy. The AUIRS3241S can be driven directly from the battery voltage.
