ACPL-344JT
Automotive 2.5A Gate-Drive Optocoupler
with Integrated IGBT Desat Overcurrent Sensing,
Miller-Current Clamping, and Under-Voltage Lockout Feedback
Data Sheet
Description
The Avago Technologies Automotive 2.5A Gate-Drive
Optocoupler features fast propagation delay with
excellent timing-skew performance. Smart features that
are integrated to protect the IGBT include IGBT
desaturation sensing with soft-shutdown protection
and fault feedback, under-voltage lockout and feedback,
and active Miller-current clamping. This full-featured
and easy-to-implement IGBT gate-drive optocoupler
comes in a compact, surface-mountable SO-16 package
for space savings. It is suitable for traction power-train
inverter, power converter, battery charger, air-con, and
oil-pump motor drives in HEV and EV applications and
satisfies automotive AEC-Q100 semiconductor
requirements.
Avago's R2Coupler isolation products provide reinforced
insulation and reliability that deliver safe-signal isolation
critical in automotive and high-temperature industrial
applications.
