LT1160IS#PBF

Overview

The LT1160IS#PBF is a half-bridge and full-bridge N-channel power MOSFET driver manufactured by Analog Devices Inc. It is designed to drive high-side and low-side N-channel power MOSFETs in bridge configurations. The device operates with supply voltages up to 35V and provides sufficient current to rapidly switch external MOSFETs, minimizing switching losses. It features independent PWM inputs for the high-side and low-side drivers, allowing for precise control of the bridge output. The IS suffix indicates an industrial temperature range operation.

Feature Summary

• Provides robust gate drive capability for N-channel power MOSFETs in half-bridge and full-bridge topologies
• Features independent PWM inputs for high-side and low-side channels to enable flexible control schemes
• Designed for efficient switching performance to reduce power dissipation in motor drives and inverters

Applications

• Half-bridge and full-bridge DC motor controllers
• Inverter circuits for AC motor drives
• High-side and low-side switching applications requiring N-channel MOSFETs

Procurement Notes

Verify the specific package variant (SOIC-8) and temperature grade (Industrial) against the project requirements. Confirm RoHS compliance status as indicated by the PBF suffix. Check for obsolescence or lifecycle changes directly from Analog Devices documentation before finalizing procurement plans.

Selection Notes

Select this component when driving N-channel MOSFETs in bridge configurations is required. Ensure the input voltage levels are compatible with the logic family used. Verify that the peak output current capabilities meet the gate charge requirements of the selected power MOSFETs for the intended switching frequency.

Part Context

The LT1160 belongs to a family of cost-effective gate drivers from Analog Devices. It is often paired with complementary P-channel drivers or used in conjunction with other bridge drivers like the LT1162 for full-bridge implementations. The IS#PBF designation specifies the industrial temperature range and lead-free packaging.
