Description
The IR21141/IR22141 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
electromagnetic emissions. In multi-phase systems, the IR21141/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.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to V
SS
, all currents are defined positive into any lead The thermal resistance
and power dissipation ratings are measured under board mounted and still air conditions.

While internal circuitry is operational below the indicated supply voltages, the UV lockout disables the output
drivers if the UV thresholds are not reached. A minimum supply voltage of 8V is recommended for the driver
to operate safely under switching conditions at VS pin (please refer to the “start-up sequence” in application
section of this document)
