LTC1693-1IS8#PBF

Overview

The LTC1693-1IS8#PBF is a high-speed N-channel MOSFET gate driver manufactured by Analog Devices. It operates within a supply voltage range of 4.5 V to 13.2 V and supports input voltages up to 14 V. The device features two drivers with non-inverting configuration, delivering an output current of 1.5 A. Key timing parameters include a propagation delay of 130 ns, rise time of 48 ns, and fall time of 42 ns. It functions reliably across an operating temperature range of -40°C to +85°C and is housed in an SOIC-8 surface-mount package.

Feature Summary

• Provides high-speed switching capabilities for N-channel MOSFETs with low propagation delay
• Supports both high-side and low-side driving configurations
• Delivers robust 1.5 A output current capability
• Operates with non-inverting logic inputs

Applications

• Synchronous rectification circuits
• DC-DC converter topologies
• Motor control systems

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the SOIC-8 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for any recent manufacturing changes or PCNs that may affect pinout or electrical characteristics.

Selection Notes

Select this component when high-speed switching of N-channel MOSFETs is required in compact designs. It is suitable for applications needing independent high-side and low-side drive signals from a single package. Consider the 1.5 A peak current capability against your MOSFET gate charge requirements. Evaluate the 4.5 V minimum supply voltage against your available logic levels.
