AUIRS20302S
Description
The AUIRS20302S is a three phase gate driver dedicated to BLDC motor drive up to 600W. Proprietary HVIC technology enables this rugged monolithic design with enforced Automotive ESD & Latch-up grades. Primarily designed for 24V battery application, its drive capability goes from 12v to 200V which cover all the abnormal conditions of the vehicle. The gate drive circuitry features cross-conduction preventive and minimum dead-time blocks. It is powered by a constant voltage so that the gate drives never exceed 17V including during Load Dump condition. An external MOSFET is acting as a pre-regulator. The inner charge pump and voltage control loop drives its gate in order to keep the VPR pin constant when the battery voltage varies. The AUIRS20302S also features an overcurrent protection that definitively shuts down all gates in case of short-circuit. The fault condition is reset by cycling the FRST pin while the I.C is disabled. A blanking time, synchronized with each high side switch command, avoids any premature triggering of the protection. The logic control block of the AUIRS20302S is developed in order to support a fast and reliable 3 phase BLDC design. For example, its inputs are compatible with the 3.3V logic processors and feature a short-pulse/noise rejection filter. The 6 commands include matched propagation delays, shoot-through protections and minimum dead-time. The bootstrap capacitor voltage of each phase is monitored independently (UVLO). Also, the maximum gate voltage is controlled by the pre-regulator in all conditions. No linear or abnormal gate drive is possible. The VPR pin can also supply the surrounding system components if the total consumption doesn’t exceed 0.1A.
