The MC33662BSEF is an integrated circuit driver IC from ON Semiconductor that combines a receiver, a gate driver and an isolated flyback with a fault indicator. It is a bi-directional line driver that includes a receiver, a driver, and a fault indication circuit. The driver is based on ON Semiconductor’s proprietary MDmesh™ MOSFET technology, incorporating a self-amplifying effect that is thermally stable and produces no ringing in the shift operation.

The MC33662BSEF Driver is designed to drive and interface with motor controllers and drive modules, motor control applications and general load switching. It is an isolated gate driver with integrated fault indication and separate flyback pin-out.

The MC33662BSEF can be used in a wide range of applications such as motor controllers, motor control applications, load switch applications, and general system level interface solutions. It has a wide operating temperature range of -40 °C to +125 °C.

Working principle

The MC33662BSEF is a line driver IC that uses a current-comparator architecture. This architecture allows for precision, fast switching and a low propagation delay. The receiver consists of two comparators and is used to detect and compare two logic levels and/or two voltage levels.

When a signal is received by the receiver, the output of the comparator is used to activate the Gate Driver, which then drives the FET, making the output Logic High. The Fault circuit is used to indicate a fault condition when the FET is not responding to the driver-input or is stuck in either logic state.

The MC33662BSEF also has a separate flyback-pinout, which is used to maintain a constant status level on the output line when the driver is not being activated, allowing the line to enter a non-driven or non-energized state. This makes it ideal for applications where the output needs to be idle, such as motor control applications.

Conclusion

The MC33662BSEF is an integrated circuit driver IC from ON Semiconductor which combines a receiver, gate driver, and fault indicator. It is a bi-directional line driver that is suitable for a range of applications such as motor controllers, motor control applications, load switch applications and general system level interface solutions. The MC33662BSEF features a current-comparator architecture for precision switching, low propagation delay, and separate flyback-pinout for constant status level on the output line.
