LTC2933IDHD#TRPBF

Supervisors Overview

The LTC2933IDHD#TRPBF is a hex programmable voltage monitoring device manufactured by Analog Devices Inc. It operates within a supply voltage range of 3.4 V to 13.9 V and features an operating supply current of 700 uA. The component provides six independent voltage supervision channels with open-drain or open-collector outputs and active low reset functionality. It utilizes a 16-pin DFN package and includes EEPROM for configuration storage. The device ensures robust power-system supervision in safety-critical automotive applications, maintaining operation between -40°C and +85°C.

Supervisors Feature Summary

• Hex programmable voltage monitoring with integrated EEPROM for flexible configuration
• Robust power-system supervision designed for safety-critical automotive applications
• Open-drain or open-collector output options with active low reset signal

Supervisors Applications

• Safety-critical automotive power system supervision
• Multi-voltage monitoring in industrial control systems
• Embedded processor supervisor circuits requiring configurable thresholds

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the manufacturer is Analog Devices Inc. as listed in official documentation. Check current availability status as distribution may vary. Ensure the part number matches the exact hex supervisor specification rather than similar single-channel variants.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous monitoring within a compact footprint. The integrated EEPROM allows field-adjustable thresholds without external components. Consider the 700 uA supply current for power-sensitive designs. Verify that the 3.4 V minimum supply voltage aligns with the system's lowest operating rail.

Supervisors Part Context

This part belongs to the LTC2933 series of multi-voltage supervisors from Analog Devices. It differs from single-channel monitors by offering six independent inputs. The IDHD suffix denotes the specific temperature grade and DFN-16 package variant. It serves as a comprehensive solution for complex power management architectures requiring precise voltage tracking.

Supervisors Replacement Considerations

LTC2933IGN#PBF is a documented alternative in the same family, differing primarily in package type (SSOP vs DFN) and tube packaging. Verify pin compatibility and thermal performance before substitution. Other series members like LTC2934 offer different channel counts and should be evaluated against specific design requirements.
