HCPL Power Bipolar Transistor Base Drive Optocoupler Data Sheet Description The HCPL consists of a Silicondoped GaAs LED optically coupled to an integrated circuit with a power output stage. This optocoupler is suited for driving power bipolar transistors and power Darlington devices used in motor control inverter applications. The high peak and steady state current capabilities of the output stage allow for direct interfacing to the power device without the need for an intermediate amplifier stage. With a CMR rating of kv/µs this optocoupler readily rejects transients found in inverter applications. The LED controls the state of the output stage. Transistor Q in the output stage is on with the LED off, allowing the base of the power device to be held low. Turning on the LED turns off transistor Q and switches on transistor Q in the output stage which provides current to drive the base of a power bipolar device. Features High output current: I O (. A Peak,. A continuous) I O (. A Peak,. A continuous) kv/µs minimum Common Mode Rejection (CMR) at V CM = V Wide range (. to volts) µs typical propagation delay Recognized under UL for dielectric withstand proof test voltage of vac, minute Applications Isolated bipolar transistor base drive AC and DC motor drives General purpose industrial inverters Uninterruptable power supply Functional Diagram HCPL ANODE CATHODE Q Q V O TRUTH TABLE LED OUTPUT ON HIGH LEVEL OFF LOW LEVEL Q ON OFF Q OFF ON THE USE OF A.µF BYPASS CAPACITOR CONNECTED BETWEEN PINS AND IS RECOMMENDED.

Recommended Protection for Output Transistors During switching transitions, the output transistors Q and Q of the HCPL can conduct large amounts of current. Figure describes a recommended circuit design showing current limiting resistors R and R which are necessary in order to prevent damage to the output transistors Q and Q (see Note ). A bypass capacitor C is also recommended to reduce power supply noise.

For the continuous voltage rating refer to the IEC/EN/DIN EN Insulation Characteristics Table (if applicable), your equipment level safety specification, or Avago Application Note, Optocoupler InputOutput Endurance Voltage. Notes:. Derate absolute maximum ratings with ambient temperatures as shown in Figures 9,, and.. A bypass capacitor of. µf or more is needed near the device between and when measuring output and transfer characteristics.. LH represents the forward current when the output goes from low to high.. Device considered a two terminal device; pins are shorted together and pin are shorted together.. For devices with minimum V ISO specified at V rms, in accordance with UL, each optocoupler is prooftested by applying an insulation test voltage V rms for one second (leakage current detection limit, I IO µa).. The t PLH and t PHL propagation delays are measured from the % level of the input pulse to the % level of the output pulse.. R sets the base current (I O in Figure ) supplied to the power bipolar device. R limits the peak current seen by Q when the device is turning off.
