January 31, 2022


Ideal for industrial, building automation, IoT, and other high-power electronics applications that require fast turn-on speeds. The CPC1596 is an optically isolated MOSFET Gate Driver that requires no external power supply. It regulates an input voltage up to 570V to 12.2V for internal use. It is specifically designed for low-duty-cycle switching and low frequency operation of external power MOSFETs with 4nF of gate capacitance. The CPC1596 can be used at up to 110°C.

These MOSFET drivers couple infrared light emitting diodes with proprietary photovoltaic integrated circuits. In addition to providing voltage for turn-on of discrete MOSFETs, these patented ICs feature a gate-clamping circuit to provide fast turn-off. These devices offer a significant reduction in drive circuit complexity, board space, and cost over alternate techniques for isolated switching of MOSFETs. Used in conjunction with discrete MOSFETs, these devices are ideal for use in programmable controls, process control, instrumentation and telecommunications, replacing TRIAC/driver, mechanical relays, and bipolar components.

When input current is applied to the LED, the emitted light will activate the photodiode array and generate a voltage at the output. The optical coupling provides a high level of input-to-output isolation. These gate drivers are well suited for use in discrete solid state relay designs and other isolated switching applications.
