LT1160CN#PBF

Overview

The LT1160CN#PBF is a half-bridge N-channel power MOSFET driver manufactured by Analog Devices Inc. It operates with a supply voltage range of 5V to 20V and provides independent high-current drive outputs for both high-side and low-side MOSFETs. The device features a fixed 500ns dead-time control to prevent shoot-through currents in bridge configurations. It includes an enable input for power management and utilizes a standard 8-pin PDIP package suitable for through-hole mounting.

Feature Summary

• Independent dual-channel output configuration for driving high-side and low-side N-channel power MOSFETs in half-bridge applications
• Integrated fixed dead-time control mechanism designed to minimize cross-conduction risks during switching transitions
• Dedicated enable pin functionality allowing for precise system-level power state control and shutdown capabilities

Applications

• Half-bridge power MOSFET gate driving circuits
• Full-bridge power converter topologies requiring isolated or floating gate signals
• Motor drive systems utilizing N-channel power switches
• DC-DC converter stages employing half-bridge architectures

Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and temperature grade. Ensure the procurement channel sources components directly from authorized distributors to guarantee authenticity. Cross-reference the complete part number including the #PBF designation to confirm lead-free compliance status prior to finalizing acquisition orders.

Selection Notes

Select this component when designing half-bridge topologies that require robust N-channel MOSFET driving with integrated timing protection. Evaluate the 5V to 20V operating range against the available control logic levels. Consider the fixed dead-time characteristics relative to the target switching frequency and MOSFET turn-on/turn-off speeds to ensure adequate overlap prevention without excessive efficiency loss.

Part Context

The LT1160 belongs to a family of cost-effective gate drivers intended for medium-power switching applications. It complements other bridge driver solutions by offering a simplified architecture focused on N-channel devices. This specific variant represents the commercial grade version housed in a plastic dual in-line package, distinguishing it from higher performance or industrial grade alternatives within the broader driver portfolio.
