The SI8285CC-ISR is an isolated integrated gate-driver with advanced shoulder-shrug protection based on Fairchild\'s OptiMOS power MOSFET technology. This device is ideal for industrial and automotive applications, and its typical application fields include motor control, power supplies, solar inverters, and general power switching. As part of Fairchild\'s OptiMOS family of power switches, the SI8285CC-ISR isolates the power switch gate from its environment, providing superior protection for the low voltage control circuit while delivering an incredibly fast switching speed.

The SI8285CC-ISR is based on a balanced, bidirectional MOSFET driver, which is used to control two Silicon Carbide (SiC) MOSFETs in series. The efficiency of the two-stage driver is significantly improved, resulting in higher switching speed, improved conductance, and lower power losses. Furthermore, the two-stage process helps minimize shoot-through current, which leads to outstanding reliability and better safety in demanding operational environments.

The driver features integrated protection against short-circuiting, overtemperature, and undervoltage conditions. It also offers optional integrated inductor and capacitor for enhanced system-level design. With a supply voltage range of 4.5 to 22V, the device easily meets the demands of industrial and automotive contexts.

The SI8285CC-ISR uses a patented, dual-mode technology to reduce cross-conduction losses. In this operating mode, the device works like a bridge, and the output signal is applied to two switches simultaneously, one of which has an active and an inactive state while the other is always active. The phase-shifted gate signals minimize cross-conduction current and reduce switching losses.

The SI8285CC-ISR also takes advantage of the latest advances in integrated shoulder-shrug protection. This feature monitors the current load in the gate-drive circuit and prevents unintentional currents from flowing that could cause destruction of the device. It also reduces capacitive shifts and increases the immanent protection against potential hazards like electrostatic discharge (ESD) and short-circuit conditions.

The SI8285CC-ISR is an ideal solution for industrial and automotive applications where superior protection and fast switching are required. Its integrated, bidirectional driver design, enhanced system design capability, and robust protection features make it an excellent option for a wide range of applications.
