LTC7001MPMSE#PBF

Overview

The LTC7001MPMSE#PBF is a high-side N-channel MOSFET gate driver from Analog Devices, designed for fast switching and static switch applications. It operates with a supply voltage range of 3.5V to 15V and supports high-side voltages up to 135V (150V absolute maximum). The device features a 1Ω pull-down and 2.2Ω pull-up output stage, enabling rapid transitions with rise and fall times of 90ns and 40ns respectively. It includes an internal charge pump for 100% duty cycle capability, adjustable turn-on slew rate, and programmable undervoltage lockout thresholds. Packaged in a 16-lead MSOP with exposed pad, it supports junction temperatures up to 150°C.

Feature Summary

• Internal charge pump enables full enhancement of external N-channel MOSFETs for indefinite on-state operation
• Low impedance output stage provides fast switching speeds to minimize power loss during transitions
• Adjustable turn-on slew rate allows optimization of electromagnetic interference and switching performance
• Programmable overvoltage and undervoltage lockout thresholds provide flexible protection mechanisms

Applications

• High-frequency power conversion circuits requiring precise high-side control
• Static switch implementations where zero current flow is maintained indefinitely
• Automotive systems operating within extended temperature ranges
• Industrial motor drives utilizing high-voltage N-channel MOSFETs

Procurement Notes

Verify the specific suffix MPMSE against official Analog Devices documentation to confirm military-grade temperature ratings and material specifications. Ensure compatibility with existing board layouts regarding the MSOP-16 package dimensions and thermal pad requirements. Confirm availability status through authorized distributors as supply constraints may apply to specialized grade components.

Selection Notes

Select this component when driving high-side N-channel MOSFETs at voltages exceeding standard bootstrap limits. The internal charge pump eliminates the need for external bootstrapping diodes or capacitors in many configurations. Consider the adjustable slew rate feature if EMI reduction is critical. Verify that the input logic levels are compatible with the controlling microcontroller or FPGA signals.
