The IR2214SS/IR22141SS) is a gate driver suited to drive

Soft shutdown time (typ) 9.6µsec

a single half bridge in power switching applications. The

high gate driving capability (2A source, 3A sink) and the

low quiescent current enable bootstrap supply techniques in medium power

systems. The IR2214SS/IR22141SS driver features full short circuit protection by

Package

means of the power transistor desaturation detection. The IR2214SS/IR22141SS

manages all the half-bridge faults by turning off smoothly the desaturated tran-

sistor through the dedicated soft shut down pin, therefore preventing over-volt-

ages and reducing EM emissions. In multi-phase system IR2214SS/IR22141SS

drivers communicate using a dedicated local network (SY_FLT and FAULT/SD

signals) to properly manage phase-to-phase short circuits. The system controller

may force shutdown or read device fault state through the 3.3 V compatible CMOS

I/O pin (FAULT/SD). To improve the signal immunity from DC-bus noise, the
