Data Sheet ACPL-K43T, ACPL-K44T 2 Automotive R Coupler Wide Operating Temperature 1-MBd Digital Optocoupler in a Stretched 8-Pin Surface-Mount Plastic Package Description Features The Broadcom ACPL-K43T is a single-channel, High temperature and reliability low-speed digital interface for automotive applications high-temperature, high-CMR, high-speed digital optocoupler in an eight-lead miniature footprint specifically Ultra-low drive for status feedback at I = 0.8 mA or F 1.5 mA used in the automotive applications. The ACPL-K44T is a dual-channel equivalent of the ACPL-K43T. Both products 30 kV/s (typ.) high common-mode rejection at V = 1500V are available in the stretched SO-8 package outline CM designed to be compatible with standard surface-mount Compact, auto-insertable stretched SO8 packages processes. Qualified to AEC Q100 Grade 1 test guidelines Wide operating temperature range: 40C to +125C This digital optocoupler uses an insulating layer between High speed: 1 MBd the light-emitting diode and an integrated photo detector to Low propagation delay: 1 s max. at I = 10 mA F provide electrical insulation between input and output. Worldwide safety approval: Separate connections for the photodiode bias and output UL 1577 approval, 5 kV /1 min. transistor collector increase the speed up to a hundred RMS CSA approval times over that of a conventional photo-transistor coupler by IEC/EN/DIN EN 60747-5-5 reducing the base-collector capacitance. 2 Applications Broadcom R Coupler isolation products provide with reinforced insulation and reliability that deliver safe signal Automotive IPM driver for DC-DC converters and motor isolation, which is critical in automotive and inverters high-temperature industrial applications. Status feedback and wake-up signal isolation CANBus and SPI communications interface High-temperature digital/analog signal isolation CAUTION Take normal static precautions in handling and assembly of this component to prevent damage, degradation, or both, which may be induced by ESD.
