ACPL-K49T Wide Operating Temperature Automotive R2CouplerTM 20 kBd Digital Optocoupler Configurable as Low Power, Low Leakage Phototransistor Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description Features The ACPL-K49T is a single channel, high temperature, high CMR, 20 kBd digital optocoupler, configurable as a low power, low leakage phototransistor, specifically for use in automotive applications. The stretched SO-8 stretched package outline is designed to be compatible with standard surface mount processes. • High Temperature and Reliability low speed digital interface for Automotive Application. 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.

Notes: 1. Current Transfer Ratio in percent is defined as the ratio of output collector current, IO, to the forward LED input current, IF, times 100. 2. Device considered a two terminal device: pins 1, 2, 3 and 4 shorted together, and pins 5, 6, 7 and 8 shorted together. 3. In accordance with UL 1577, each optocoupler is proof tested by applying an insulation test voltage > 6000 VRMS for 1 second. 4. Common transient immunity in a Logic High level is the maximum tolerable (positive) dVCM/dt on the rising edge of the common mode pulse, VCM, to assure that the output will remain in a Logic High state (i.e., Vo > 2.0 V). Common mode transient immunity in a Logic Low level is the maximum tolerable (negative) dVCM/dt on the falling edge of the common mode pulse signal, VCM to assure that the output will remain in a Logic Low state (i.e., Vo < 0.8 V). 6 NORMALIZED CURRENT TRANSFER RATIO NORMALIZED CURRENT TRANSFER RATIO 1.8 TA = 25° C VCC = 5 V VO = 0.4 V 1.6 1.4 1.2 1.0 0.8 0.6 0.4 0.2 0.0 0.1 1 10 IF - INPUT CURRENT (mA) 100 Figure 1.

Figure 12. Test Circuit for Transient Immunity and Typical Waveforms (4-Pin Configuration) Thermal Resistance Model for ACPL-K49T The diagram of ACPL-K49T for measurement is shown in Figure 13. Here, one die is heated first and the temperatures of all the dice are recorded after thermal equilibrium is reached. Then, the 2nd die is heated and all the dice temperatures are recorded. With the known ambient temperature, the die junction temperature and power dissipation, the thermal resistance can be calculated. The thermal resistance calculation can be cast in matrix form. This yields a 2 by 2 matrix for our case of two heat sources.
