New photocoupler for industrial motor control and inverter applications with extended operating temperature



Toshiba Electronics Europe (TEE) has announced an ultra-compact, extended temperature photocoupler that provides a space-saving solution for industrial applications that require an isolation interface between intelligent power modules (IPMs) and IC control circuitry. Ideally suited to industrial motor control and general-purpose inverter applications, the new TLP2404 provides a minimum isolation voltage of 3750Vrms. Operation is guaranteed across the extended industrial temperature range of -40°C to 125°C. Toshiba's TLP2404 features an inverter logic, open collector output and offers transmission rates up to 1Mbps. Maximum transmission delay time is only 550ns and maximum switching time dispersion is just 400ns. The new photocoupler is based around a GaAlAs LED that is optically coupled to an integrated, high-gain, high-speed photodetector. A wide input capability supports input voltages from 4.5V to 30V and an internal Faraday shield ensures a guaranteed, minimum common mode transient immunity of ±15kV/μs. Supplied in a surface mount SO8 package, the TLP2404 measures just 6.0mm x 5.1mm x 2.5mm.
