Beverly, Mass.Clare Inc. has released the CPC1580, the first device in a family of optically isolated MOSFET gate drivers, providing 3750-Vrms of input-to-output isolation.
An external power MOSFET is controlled by applying sufficient input LED current (2.5 to 10mA) in the CPC1580 to activate the internal load-side driver circuit. The CPC1580 IC connected to the load, together with an external storage capacitor, provides sufficient bias to the internal driver circuit, eliminating the external power supply.
The CPC1580 is designed for low duty cycle switching frequencies and offers isolated solid state control to replace large modules and multi-component discrete products.
The CPC1580 has a blocking voltage rating of 65V, which is paired with a corresponding external MOSFET for a variety of power switching applications. The CPC1580 features a typical turn-on time of 150 micro-seconds (Ton = 150s) and a typical turn-off time of 240 micro-seconds (Toff = 240s) with a 2.5mA LED current.
