LTC4372IMS8#PBF

OR Controllers, Ideal Diodes Overview

The LTC4372IMS8#PBF is a low quiescent current ideal diode controller manufactured by Analog Devices Inc. in an 8-lead MSOP package. It 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. The device provides reverse power protection down to -28V and achieves reverse current turn-off in 1.5μs or less. Designed for industrial applications, it supports a temperature range from -40°C to +85°C.

OR Controllers, Ideal Diodes Feature Summary

• Drives external N-channel MOSFETs to replace Schottky diodes, significantly reducing forward voltage drop and conduction losses.
• Provides rapid reverse current blocking within 1.5μs to protect against power supply faults and short circuits.
• Supports back-to-back MOSFET configurations for precise surge current control and load switching functions.

OR Controllers, Ideal Diodes Applications

• Redundant power systems utilizing N+1 OR-ing architectures
• Automotive battery protection circuits
• Solar panel bypass diode implementations
• Uninterruptible Power Supply (UPS) hold-up circuits

OR Controllers, Ideal Diodes Procurement Notes

Verify the IMS8 suffix confirms the industrial temperature grade (-40°C to +85°C) required for your specific environment. Confirm that the #PBF designation indicates lead-free compliance and RoHS adherence. Ensure the MSOP-8 footprint matches your PCB layout constraints before finalizing procurement orders.

OR Controllers, Ideal Diodes Selection Notes

Select this component when ultra-low static current is critical for battery life or standby efficiency. Choose the IMS8 variant specifically for standard industrial environments requiring operation up to 85°C. Consider the HMS8 variant if extended high-temperature performance up to 125°C is necessary for automotive or harsh industrial conditions.

OR Controllers, Ideal Diodes Part Context

This part belongs to the LTC4372 series of ideal diode controllers, designed to manage power flow efficiently using external MOSFETs. The IMS8 suffix distinguishes it as the industrial temperature grade version, differing from the commercial CMS8 and high-temperature HMS8 variants primarily by its specified operating temperature range limits.

OR Controllers, Ideal Diodes Replacement Considerations

LTC4372HMS8#PBF offers identical electrical specifications but extends the maximum operating temperature to 125°C for automotive use. LTC4372CMS8#PBF provides the same functionality with a reduced commercial temperature range of 0°C to 70°C.
