ACPL-K305T Automotive Photovoltaic Drivers
Broadcom ACPL-K305T Automotive Photovoltaic Drivers with R2Coupler™ isolation are designed to drive high-voltage MOSFETs and/or IGBTs. These drivers provide reinforced insulation and reliability that deliver safe signal isolation critical in automotive and high-temperature industrial applications. The ACPL-K305T drivers consist of an AlGaAs infrared 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 with a minimum input current of 3mA through the input LED. The MOSFET driver is turned off with an input voltage of 0.6V or less. The ACPL-K305T drivers are used in applications like solid-state relays, high-side power switch control, battery management systems, and precharge/active discharge circuits in high-voltage systems.
