LTC1177IN-5

Overview

The LTC1177IN-5 is a high-side gate driver IC manufactured by Analog Devices Inc. It operates with a supply voltage range of 4.75V to 5.25V and features a non-inverting configuration for driving power switches. The device is housed in an 18-DIP package, providing a width of 0.300 inches (7.62mm). It is designed for applications requiring reliable high-side switching control within standard logic voltage levels.

Feature Summary

• Non-inverting high-side gate driver configuration
• Compatible with standard 5V logic supply voltages
• Designed for driving external power switches

Applications

• High-side switching control in power management circuits
• Driver stages for MOSFET or IGBT power devices
• DC-DC converter topologies requiring isolated or floating high-side drive

Procurement Notes

Verify the specific suffix 'IN-5' against the official Analog Devices datasheet to confirm the 18-DIP package and 5V supply specification. Ensure compatibility with your system's logic voltage levels before integration. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a dedicated high-side driver is required for 5V logic systems. Consider the 18-DIP package constraints for PCB layout and thermal management. Verify that the load current requirements of the driven switch fall within the driver's output capabilities as defined in the electrical characteristics table.

Part Context

This part belongs to the Linear Technology (now Analog Devices) family of power management integrated circuits. It serves as a specialized interface between low-power control logic and high-power switching elements, ensuring efficient signal transmission in power conversion applications.

Replacement Considerations

Check for direct pin-compatible alternatives from Analog Devices such as other variants in the LTC1177 series. Verify that any substitute maintains the same 18-DIP footprint and 5V operating voltage range.
