LTC7000HMSE#PBF

Overview

The LTC7000HMSE#PBF is a high-side N-channel MOSFET gate driver from Analog Devices, designed for static switching applications. It operates with an input supply voltage range of 3.5 V to 135 V and supports a bias voltage of 3.5 V to 15 V. The device features fast switching characteristics with a rise time of 90 ns and a fall time of 40 ns. It is housed in a 16-lead MSOP package with an exposed pad and functions within a temperature range of -40°C to +150°C.

Feature Summary

• Provides 100% duty cycle capability for indefinite on-state operation of external N-channel MOSFETs via an internal charge pump.
• Integrates overcurrent detection by monitoring the voltage across an external sense resistor connected in series with the switch drain.
• Includes automatic retry functionality following fault conditions, with the retry duration determined by an external timing capacitor.

Applications

• High-frequency static switching circuits
• Industrial motor control systems
• Power management modules requiring high-side protection

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the HMSE variant meets the required extended temperature rating of up to 150°C. Ensure the MSOP-16 package dimensions align with the target PCB footprint. Validate that the 135 V maximum operating voltage suits the system's peak transient requirements.

Selection Notes

Select this component when driving high-side N-channel MOSFETs with ground-referenced logic signals. It is suitable for applications requiring integrated current limiting and adjustable turn-on slew rates. Consider the LTC7000-1 if fewer control pins are needed, or the IMSE variant if industrial temperature ratings suffice.

Part Context

This part belongs to the LTC7000 family of high-voltage gate drivers. It shares core architecture with variants like the LTC7000IMSE but differs in thermal performance and packaging specifications. The family targets robust power switching solutions where high-side drive reliability and protection features are critical.

Replacement Considerations

LTC7000IMSE#PBF offers similar functionality with standard industrial temperature ratings. LTC7000EMSE-1#TRPBF provides tape-and-reel packaging options. Verify pin compatibility and thermal limits when substituting these related models.

FAQ

How does the LTC7000HMSE#PBF handle overcurrent conditions?

It detects overcurrent by monitoring the voltage across an external sense resistor. Upon detecting a fault, it shuts down the switch and initiates an automatic retry after a period set by an external capacitor.

What is the maximum operating voltage for this driver?

The device supports a maximum input supply voltage of 135 V, with a peak absolute maximum rating of 150 V.
