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 (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.
