LTC7001IMSE#PBF

Overview

The LTC7001IMSE#PBF is a high-speed, high-side N-channel MOSFET gate driver manufactured by Analog Devices Inc. It operates with a supply voltage range of 3.5V to 15V and supports drain voltages up to 135V, with an absolute maximum rating of 150V. The device features a 1Ω pull-down and 2.2Ω pull-up output stage, enabling fast switching with a typical propagation delay of 35ns and rise/fall times of 13ns for a 1000pF load. It includes an internal charge pump for 100% duty cycle capability, adjustable turn-on slew rate, and programmable under-voltage lockout (UVLO) and over-voltage lockout (OVL). Packaged in a 10-lead MSOP with exposed pad.

Feature Summary

• Internal charge pump enables full enhancement of external N-channel MOSFETs for indefinite on-state operation.
• Low impedance output stage provides rapid switching transitions to minimize power loss during high-frequency operation.
• Programmable protection thresholds allow customization of turn-on slew rates and over-voltage lockout levels.

Applications

• High-frequency switching power supplies
• Static switch applications requiring high-side control
• Motor drive systems utilizing N-channel MOSFETs

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm the package variant matches the required thermal performance and pinout compatibility for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to ensure all electrical characteristics and mechanical dimensions align with current production standards before finalizing procurement.

Selection Notes

Select this component for designs requiring precise control of high-side N-channel MOSFETs with minimal propagation delay. The adjustable UVLO and OVL features provide flexibility for varying input voltage conditions. Ensure the external MOSFET gate capacitance is compatible with the driver's output current capabilities to maintain the specified switching speeds without excessive heat generation.
