FAN7085CM_F085

Gate Driver Overview

The FAN7085CM_F085 is a single high-side gate driver IC designed for driving MOSFETs and IGBTs in high-voltage applications. It features an integrated charge pump with a built-in recharge FET, eliminating the need for external bootstrap components. The device supports supply voltages from 4.5 V to 20 V and operates with bus voltages up to 300 V. Key electrical parameters include a peak output current of 250 mA, rise and fall times of 200 ns, and maximum delay times of 1 µs (on) and 0.5 µs (off). It functions within a temperature range of -40 °C to +125 °C and is housed in an SOIC-8 surface-mount package.

Gate Driver Feature Summary

• Integrates a charge pump with a dedicated recharge FET for efficient high-side gate drive without external bootstrap capacitors.
• Provides robust high-voltage isolation capable of operating with source potentials up to 300 V.
• Features a reset input pin to ensure controlled shutdown and prevent unintended switching events.
• Utilizes advanced level-shifting technology to maintain stable operation under high dV/dt noise conditions.

Gate Driver Applications

Gate Driver Procurement Notes

Verify component authenticity through authorized onsemi distribution channels or certified partners. Confirm that the specific suffix matches the required packaging and automotive qualification standards. Request official datasheets and compliance certificates to validate technical specifications against application requirements before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a compact solution for high-side driving is required without external bootstrap circuitry. The integrated recharge FET simplifies PCB layout and reduces component count compared to traditional drivers. Ensure the 300 V voltage rating aligns with the system's bus voltage and consider the 250 mA output current capability relative to the target MOSFET or IGBT gate charge requirements.

Gate Driver Part Context

This part belongs to the FAN708x series of high-side gate drivers from onsemi. It shares architectural similarities with other models in the family but is distinguished by its specific voltage ratings and internal recharge capabilities. The series is engineered for reliability in harsh electromagnetic environments typical of industrial and automotive power electronics.

Gate Driver Replacement Considerations

Direct substitutes may include other high-side drivers with integrated recharge FETs from onsemi, such as the FAN7085M-GF085. Verify pin compatibility and electrical parameters before substitution. Note that some variants may be end-of-life; consult official replacement guides for active equivalents.
