Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required package and temperature grade. Request original manufacturer documentation to validate RoHS compliance and traceability. Ensure storage conditions maintain integrity prior to assembly.

Selection Notes

Select this component when high-side drive is required for voltages up to 80 V. Consider the MSOP-E package size constraints and thermal requirements. Evaluate the 2.4 A output current against the target MOSFET gate charge. Verify that the bootstrap circuit design accommodates the specified rise and fall times for the application frequency.

Part Context

This part belongs to the LTC4440 series of high-voltage gate drivers. It is specifically engineered for applications requiring robust high-side switching performance.
