1 / 11 page ACPL-K43T, ACPL-K44T Automotive R2CouplerTM Wide Operating Temperature 1MBd Digital Optocoupler in a Stretched 8-Pin Surface Mount Plastic Package Data Sheet CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description The ACPL-K43T is a single channel, high temperature, high CMR, high speed digital optocoupler in an eight lead miniature footprint specifically used in the automotive applications. The ACPL-K44T is a dual channel equiva- lent of the ACPL-K43T. Both products are available in the stretched SO-8 package outline, designed to be compat- ible with standard surface mount processes. This digital optocoupler uses an insulating layer between the light emitting diode and an integrated photo detector to provide electrical insulation between input and output. Separate connections for the photodiode bias and output transistor collector increase the speed up to a hundred times over that of a conventional photo-transistor coupler by reducing the base-collector capacitance. Avago R2Coupler isolation products provide with rein- forced insulation and reliability that delivers safe signal isolation critical in automotive and high temperature industrial applications. Functional Diagram Note: The connection of a 0.1 F bypass capacitor between pins 5 and 8 is recommended. Features High Temperature and Reliability low speed digital interface for Automotive Application Ultra low drive for status feedback at IF = 0.8 mA or 1.5 mA 30 kV/s (Typ) High Common-Mode Rejection at VCM = 1500 V Compact, Auto-Insertable Stretched SO8 Packages Qualified to AEC Q100 Grade 1 Test Guidelines Wide Operating Temperature Range: -40° C to +125° C High Speed: 1 MBd Low Propagation Delay: 1 s max. at IF = 10 mA Worldwide Safety Approval: – UL 1577 approval, 5 kVRMS/1 min. – CSA Approval – IEC/EN/DIN EN 60747-5-5 Applications Automotive IPM Driver for DC-DC converters and motor inverters Status Feedback and Wake-Up Signal Isolation CANBus and SPI Communications Interface High Temperature Digital/Analog Signal Isolation Truth Table LED Vo ON LOW OFF HIGH 7 1 2 3 45 6 8 ANODE CATHODE NC NC VCC VO NC GND ACPL-K43T 7 1 2 3 45 6 8 ANODE1 CATHODE1 CATHODE2 ANODE2 VCC VO1 VO2 GND ACPL-K44T |
