Description

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.
