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 (SY_FLT and FAULT/SD signals) to properly manage phase-to-phase
short circuits. The system controller may force shutdown or readwww.DataSheet.co.kr 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.
