LTC4372HMS8#TRPBF

OR Controllers, Ideal Diodes Overview

The LTC4372HMS8#TRPBF is a low quiescent current ideal diode controller manufactured by Analog Devices Inc. It drives external N-channel MOSFETs to replace power Schottky diodes, significantly reducing conduction losses and heat generation. The device operates within a voltage range of 2.5V to 80V and features a typical operating current of 5μA with a shutdown current of 0.5μA. It provides reverse power protection down to -28V and achieves fast reverse current turn-off in ≤1.5μs. The component is housed in an 8-lead MSOP package and is rated for an industrial temperature range of -40°C to +125°C.

OR Controllers, Ideal Diodes Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm that the H-grade designation meets the required -40°C to +125°C operational temperature specifications for your application environment. Ensure compatibility with external N-channel MOSFET gate drive requirements before finalizing procurement orders.

OR Controllers, Ideal Diodes Selection Notes

Select this model for high-voltage applications requiring minimal standby power consumption. The H-grade variant is suitable for harsh environments demanding extended temperature stability. Consider the MSOP-8 footprint for space-constrained designs. Evaluate external MOSFET selection based on the controller's gate drive capabilities and the system's voltage and current ratings.
