IO+/- (typ.) 2.0 A / 3.0A VOUT 10.4V - 20V Deadtime matching (max) 75nsec Deadtime (typ) 330nsec Desat blanking time (typ) 3µsec DSH,DSL input voltage threshold (typ) 8.0V Soft shutdown time (typ) 9.6µsec Description LIN IR2214SS/IR22141SS IR2214 The IR2214SS/IR22141SS) is a gate driver suited to drive 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 means of the power transistor desaturation detection. The IR2214SS/IR22141SS manages all the half-bridge faults by turning off smoothly the desaturated transistor through the dedicated soft shut down pin, therefore preventing over-voltages 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 contr...
