Gate drive optocouplers

10 July 2013 Opto-Electronics

Renesas Electronics and California Eastern Laboratories (CEL) have introduced three isolated gate drive optocouplers which were specifically designed to meet the demanding isolation requirements of motor controls and drives,

industrial inverters and induction heating equipment.

Each variant optimises a different feature set which allows end users to select the ideal component for their specific applications.

Geared specifically for the industrial market, the entire family extends the upper temperature limit to 110°C. Each variant also yields a common mode transient immunity (CMTI) of 25 kV/μs.

The PS9905 delivers the greatest creepage distance within the family with a rating of 14,5 mm. This allows the end user to design 690 V or greater drives while complying with IEC standards. Essentially this device replaces two optocouplers in traditional designs with a single isolator, thereby reducing the overall footprint by 30%.

The PS9308 offers the smallest form factor of the family, using only half the space of a standard 8-pin DIP. In addition, it provides the lowest current, fastest switching speed and highest noise immunity (i.e. CMTI performance).

The PS9402 adds desaturation detection and active Miller clamping to the optocoupler lineup, while offering excellent noise immunity, reduced current draw and expanded temperature ratings. Each of these features makes the PS9402 an ideal device for driving IGBTs and power MOSFETs.
