Toshiba Electronics Europe has introduced two new high-speed optocouplers. The TLP2745 and TLP2748 IC output optocouplers feature low pulse width distortion (PWD) and low power consumption, enabling high-speed, high-temperature operation.
They are designed for applications such as high-speed digital interfaces for measurement or control equipment, intelligent power module (IPM) drivers, and programmable logic controllers for industrial environments.
TLP2745 is a buffer logic type (high input → high output) optocoupler, while TLP2748 is an inverter logic type (high input → low output) coupler, both of which provide the smallest isolation voltage. 5000Vrms.
In recent years, the demand for energy-saving products has brought about a demand for more efficient power systems. These new ICs have a high-speed propagation delay time of 120 ns (max), which improves operating efficiency, while “guaranteing” 40 ns (max) pulse width distortion and 70 ns (max) propagation delay skew, which can reduce inversion Device's dead time, thereby improving power efficiency as a whole. In addition, by guaranteeing a threshold input current of 1.6 mA (maximum), they allow direct drive from a microcomputer without buffering, thereby reducing energy consumption and costs.
These ICs have an operating temperature range of -40C to 110C and a wide supply voltage range (VCC = 4.5 to 30V) and are suitable for communication interfaces (such as RS232, RS422, and RS485), including data and data used in industrial applications. Transmission solution between circuits of different voltages. Both the TLP2745 and TLP2748 are available in SO6L packages with a size of 10mm x 3.8mm x 2.1mm. They ensure a minimum creepage distance. The company says 8 mm.
