The IR22141SS
The IR22141SS is a half bridge gate driver suited for power switching applications. The high side driver
can float up to 1200V. The IR22141SS have a high gate driving capability (2A source and 3A sink) with
a low quiescent current. The device is designed to manage all the half-bridge faults by turning off
smoothly the desaturated transistor through the dedicated soft shut down pin preventing over-voltages
and reducing EM emissions. In a multi-phase system the 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.
For further technical information see the IR2214/IR22141 datasheet at http://www.irf.com.
The power module
IRMD22141SS demo board is ECONO2 compatible with
SixPack? standard pin out.
Important Notice
IRMD22141SS demo board is supplied with a Bill Of Material
suitable for a 1200V/50A@100C power module. The BOM
presented on page 15 provides a suggestion for the above
mentioned power module.
It is strongly recommended to customize the demo board to fit the application requirements for the
power module that has been chosen.
Suggestions on passive sizing are also present in “Design Tips: Using monolithic high voltage gate
drivers”.
