It requires a minimal amount of LED drive current to operate, making them ideal for battery powered and power consumption sensitive applications. • Battery powered switch applications • General telecom switching • Telephone line interface - On/off hook - Ring relay - Ground start 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, switch-control circuitry, and MOSFET switches. In addition, the relays employ current-limiting circuitry enabling it to pass lightning surge testing as per ANSI/TIA-968-B and other regulatory surge requirements when overvoltage protection is provided. • Programmable controllers • Instrumentation AGENCY APPROVALS UL1577: file no.

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 fold back characteristic. When the overload is removed, the relay resumes its normal on-resistance characteristic. +I 210 mA ILMT 10 Ω IK 60 mA 16 Ω - 1.5 V -V 16 Ω 1.5 V +V 60 mA IK 10 Ω ILMT - 210 mA -I ilh1540acd_01 Fig. 1 - Typical AC/DC on Characteristics 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 drive voltage for the MOSFET switch outputs. For high temperature or high-load current operations, more LED current is required.
