They require a minimal amount of LED drive current to operate, making them ideal for battery powered and power consumption sensitive applications. The relays are constructed using a GaAlAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a high-voltage dielectrically isolated BCDMOS technology, is comprised of a photodiode array, switchcontrol circuitry, and MOSFET switches. In addition, the relays employ current-limiting circuitry enabling it to pass FCC 68.302 and other regulatory surge requirements when overvoltage protection is provided. The LH1525 (1 Form A) is packaged in an 8-pin, plastic SOP (LH1525ACD). Available in sticks or on tape and reel. Figure 1. LH1525ACD Functional/Pin Diagram S HEAT SINK 8 5 S S S 1 Siemens Microelectronics, Inc. • Optoelectronics Division www.smi.siemens.com/opto/ S' 8 of 25 2 3 S' 4 October 1998 Functional Description Figure 3 shows the switch characteristics of the relays. The relay exhibits an ON-resistance that is exceptionally linear through the origin and up to the knee current (Ik). Beyond Ik, the incremental resistance decreases, minimizing internal power dissipation. Overload currents are clamped at ILMT by the internal current-limit circuitry. The current-limiting circuitry exhibits a negative temperature coefficient, thereby reducing the current-limit value when relay temperature is increased. An extended clamp condition, which increases relay temperature, decreases the current-limit value, resulting in a current foldback characteristic. When the overload is removed, the relay resumes its normal ONresistance characteristic. In a 1 Form A relay, to turn the relay on, forward current is applied to the LED. The amount of current applied determines the amount of light produced for the photodiode array. This photodiode array develops a drivevoltage for the MOSFET switch outputs. For hightemperature or high-load current operations, more LED current is required. Thermal Considerations To minimize thermal resistance, pins 6 and 7 of the LH1525ACD are formed into a tab. This tab should be soldered to a printed circuit board land pattern of equal or greater size. Do Not run metal underneath the device or the input-to-output isolation could be jeopardized. Figure 3.

Input Control Circuit Input Control The LH1525 low turn-on current SSR has highly sensitive photo-detection circuits that will detect even the most minute currents flowing through the LED. Leakage current must be considered when designing a circuit to turn on and off these relays. Figure 23 shows a typical logic circuit for providing LED drive current. R1 is the input resistor that limits the amount of current flowing through the LED. For 5 V operation, a 2700 W resistor will limit the drive current to about 1.4 mA. Where high-speed actuation is desireable, use a lower value resistor for R1. An additional RC peaking circuit is not required with the LH1525 relay. VS R2 100 kW ANY TTL OR BUFFERED CMOS LOGIC R1 2700 W SSR R2 is an optional pull-up resistor which pulls the logic level high ouput (VOH) up toward the VS potential. The pull-up resistance is set at a high value to minimize the overall current drawn from the VS. The primary purpose of this resistor is to keep the differential voltage across the LED below its turn-on threshold. LED dropout voltage is graphed vs. temperature in the Typical Performance Characteristics section. When the logic gate is high, leakage current will flow through R2. R2 will draw up to 8 mA before developing a voltage potential which might possibly turn on the LED. Many applications will operate satisfactorily without a pull-up resistor. In the logic circuit in Figure 1 the only path for current to flow is back into the logic gate. Logic leakage is usually negligible. Each application should be evaluated, however, over the full operating temperature range to make sure that leakage current through the input control LED is kept to a value less than the minimum LED forward current for switch turn-off specification.

The relay features logic-level input control of isolated high-voltage switch outputs. The output is rated at 280 V and can handle loads up to 120 mA. The relay can switch both ac and dc loads and is ideal for audio frequency or dc applications. Typical ON-resistance at 25 mA is 25 W. The LH1191 relay consists of a GaAIAs LED that optically couples control signals to a monolithic integrated circuit. Optical coupling provides 1500 Vrms of input/output isolation. The integrated circuit is a dielectrically isolated, high-voltage die comprised of photodiode arrays, switch control circuitry, and high-voltage DMOS transistor switches. In operation, the device is exceptionally linear up to 55 mA. Beyond 55 mA, the incremental resistance decreases, thereby minimizing internal power dissipation. Overload currents are clamped at 210 mA by internal current limiting. An extended clamp condition, which increases relay temperature, results in a reduction in clamp current, thereby further reducing internal power dissipation and preserving the relay’s integrity.
