The IR2114/21141/2214/IR22141 gate driver family is 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. These drivers feature full short circuit protection by means of the power transistor desaturation detection and 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 IR2114/21141/2214/IR22141 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 control and power ground use dedicated pins enabling low-side emitter current sensing as well. Undervoltage conditions in floating and low voltage circuits are managed independently.

IR21141SSPBF General Description
The IR211(4,41)/IR221(4,41) gate driver family is suited to drive a single half bridge in power switching applications. These drivers provide high gate driving capability (2 A source, 3 A sink) and require low quiescent current, which allows the use of bootstrap power supply techniques in medium power systems. These drivers feature full short circuit protection by means of power transistor desaturation detection and manage all half-bridge faults by smoothly turning off the desaturated transistor through the dedicated soft shutdown pin, therefore preventing over-voltages and reducing EM emissions. In multi-phase systems, the IR211(4,41)/ IR221(4,41) drivers communicate using a dedicated local network (123456789SY_FLT and 123456789FAULT/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 (123456789FAULT/SD). To improve the signal immunity from DC-bus noise, the control and power ground use dedicated pins enabling low-side emitter current sensing as well.
