产品特点 Features
- The ACPL-P343/W343 contains an AlGaAs LED, which is 4.0 A maximum peak output current optically coupled to an integrated circuit with a power
- 3.0 A minimum peak output current output stage. This optocoupler is ideally suited for driving
- 100 ns maximum propagation delay diff erence controlled devices. The voltage and high peak output
- LED current input with hysteresis current supplied by this optocoupler make it ideally suited for direct driving IGBT with ratings up to 1200 V 35 kV/s minimum Common Mode Rejection (CMR) at
- / 200 A. For IGBTs with higher ratings, this optocoupler V = 1500 V can be used to drive a discrete power stage which drives
- I CC = 3.0 mA maximum supply current the IGBT gate. The ACPL-P343 and ACPL-W343 have the
- Under Voltage Lock-Out protection (UVLO) with
- This thermal model assumes that an 6-pin single-channel cient gate voltage to the IGBT by forcing the ACPL-P343/ plastic package optocoupler is soldered into a 7.62 cm x
- W343 output low during power-up. IGBTs typically require
- 7.62 cm printed circuit board (PCB) per JEDEC standards.
- gate voltages of 15 V to achieve their rated V voltage.
- CE(ON) The temperature at the LED and Detector junctions of
- At gate voltages below 13 V typically, the V voltage
- CE(ON) the optocoupler can be calculated using the equations increases dramatically, especially at higher currents. At below.
- very low gate voltages (below 10 V), the IGBT may operate in the linear region and quickly overheat. The UVLO T 1 = (R 11 * P 1 + R 12 * P 2 ) + Ta (1) function causes the output to be clamped whenever
- T = (R * P + R * P ) + Ta (2)
