U2102B-MFPY Datasheet PDF - ATMEL

●Description

●The timer control circuit U2102B is based on bipolar technology. The output stage can switch either a MOSFET or an IGBT. Two sensor inputs and the retriggerable and adjustable tracking time useful for a wide range of applications. By using the reverse phase-control technique, the resistive load can be dimmed without the need of a compensation inductance. The integrated current monitoring function provides a very fast switch-off in case of a short-circuit condition. No additional fuse is needed.
