HCPL-3180-060E

Isolators - Gate Drivers

HCPL-3180-060E is an optically coupled high-side MOSFET gate driver and data signal isolator. It provides galvanic isolation between the high-side MOSFET gate drive circuit and the low-side gate drive circuit, up to 2500Vrms, allowing functional operation even in extreme environments. This isolation prevents crosstalk between the switching elements and data signals in high reliability applications. The HCPL-3180-060E provides galvanic isolation even in the event of power supply failure.

Application Field

The HCPL-3180-060E is designed for use in isolating data signal lines as well as driving MOSFETs used in DC-DC converters, motor control, HVAC, industrial communication, and automation systems. It can also be applied in applications where AC line voltage or noise immunity need to be maintained.

Working Principle

The HCPL-3180-060E provides galvanic isolation between the low-side and high-side driver circuits. The device integrates a high-side logic-level MOSFET along with an optically coupled MOSFET gate driver circuit. The optical coupling barrier isolates the high side from the low-side gate drive circuitry.

The optically coupled MOSFET gate driver circuit accepts bidirectional data signals isolated from ground, which are then transmitted to the high-side MOSFET driver circuit. The HCPL-3180-060E driver circuit has an internal voltage output range bias circuit which allows for a more efficient operation. Heat dissipation during switching is minimized due to the low switching losses of the integrated driver circuit.

Specification

The HCPL-3180-060E series provides electrical isolation up to 2500Vrms and 3A of peak output current. It offers wide operating temperature ranges from -40°C to +105°C and a fast switching speed of <100ns. It also features a differential output voltage of 5V/Noise Rejection of 500ns and a 1kV surge rating.

Conclusion

The HCPL-3180-060E is an efficient optically coupled MOSFET gate driver that provides galvanic isolation up to 2500Vrms. Its wide operating temperature range, fast switching times, and 1kV surge rating make it an excellent choice for a variety of high reliability applications. It is ideal for isolated data signal lines, isolated DC-DC converters, motor control, HVAC, industrial communication, and automation systems.
