LTC4442IMS8E#PBF

Overview

The LTC4442IMS8E#PBF is a high-speed synchronous N-channel MOSFET gate driver manufactured by Analog Devices. It features two independent drivers in an MSOP-8 package, supporting input voltages up to 38 V and operating supply voltages between 6 V and 9.5 V. The device delivers 5 A output current with propagation delays of 20 ns, rise times of 12 ns, and fall times of 8 ns. It operates within a temperature range of -40°C to +85°C and consumes 730 µA of quiescent current.

Feature Summary

• Provides high-side and low-side drive capabilities for synchronous rectification applications
• Supports high input voltage operation up to 38 V for robust switching control
• Features fast switching characteristics with nanosecond-level rise and fall times

Applications

• High-speed synchronous rectifier circuits
• N-channel MOSFET gate driving in power conversion systems
• DC-DC converter topologies requiring isolated or floating gate drive

Procurement Notes

Verify the specific suffix E#PBF against the manufacturer's latest datasheet to confirm RoHS compliance and lead-free status. Confirm the MSOP-E-8 package dimensions match your PCB footprint requirements. Ensure the 38 V maximum input rating aligns with your system's transient voltage conditions to prevent device damage.

Selection Notes

Select this component when high-speed switching performance is required for N-channel MOSFETs in synchronous configurations. The 5 A peak drive current supports moderate load applications, while the wide input voltage range accommodates various bus voltages. Consider the MSOP-8 package size for space-constrained designs requiring dual-channel isolation.
