Automotive R²Coupler™ Photovoltaic MOSFET Driver

Currently Viewing:

The Broadcom ACPL-K30T is a photovoltaic MOSFET driver device specifically designed to drive high voltage MOSFETs. The device consists of an AlGaAs infrared light-emitting diode (LED) input stage optically coupled to an output detector circuit. The detector consists of a photovoltaic diode array and a turn-off circuit. The photovoltaic driver is turned on upon a minimum input current of 10 mA through the input LED. The photovoltaic driver is turned off upon an input voltage of 0.8 V or less.

The ACPL-K30T is available in a stretched SO-8 package compatible with standard surface mount processes.

Broadcom R2Coupler isolation products provide reinforced insulation and reliability needed for critical automotive and high temperature industrial applications.
