TS61002-QFNR

Power Management - Specialized Overview

The TS61002-QFNR is a full-bridge FET driver manufactured by Semtech Corporation. It is designed to drive high-side and low-side N-channel power MOSFETs in resonant converter topologies, such as LLC or half-bridge configurations. The device integrates bootstrap diodes and level-shifters to facilitate gate drive signals for high-side switches without requiring isolated power supplies. It supports switching frequencies up to several megahertz, ensuring efficient operation in wireless power transfer systems and other high-frequency DC-DC conversion applications.

Power Management - Specialized Procurement Notes

Verify the specific suffix -QFNR indicates automotive qualification (AEC-Q100) if required for your design. Confirm package availability and lead times with authorized distributors. Ensure the ordering part number matches the exact temperature range and packaging format specified in the latest datasheet revision.

Power Management - Specialized Selection Notes

Select this component when designing resonant converters requiring integrated high-side drive capabilities. Compare against competitors based on switching frequency limits, propagation delay matching, and thermal performance. Ensure the input voltage range aligns with your system's supply rails and that the output current capability meets the gate charge requirements of your selected MOSFETs.

Power Management - Specialized Part Context

The TS61002 belongs to Semtech's family of full-bridge drivers, often paired with controllers like the TS61001.
