Toshiba – Rutronik presents new High-Speed Logic IC Coupler with Low-Power Consumption
By employing Toshiba’s high-output GaAIAs (MQW) infrared LEDs, operation is ensured from -40° up to +125°C. The LED’s high output and reliability enables low threshold input current of just 1.6mA (max.), a reduction of 54% in comparison with equivalent products. As the supply current per channel is reduced to 1mA, the TLP2361 and TLP2161 have a lower charging rate of up to 66% compared to conventional products.
Thanks to the lower input current rating, the photocouplers can be driven directly by the microprocessor without requiring a buffer, contributing to lower power consumption, lower component count and reduced costs. The receiver IC characteristics are guaranteed over a power voltage range from 2.7 to 5.5V.
TLP2361 comes in a compact SO6 package with guaranteed clearance and creepage distance of min. 5mm, and with insulation voltage of 3750Vrms.This is compliant with the reinforced insulation class of various safety standards. TLP2161, with an insulation voltage of min. 2500Vrms, combines two circuits into a SO8 package, reducing mounting area by approximately 40%, compared with two TLP2361 units. This contributes to downsizing and reducing PCB costs.
