LTC2905HDDB#TRMPBF

Supervisors Overview

The LTC2905HDDB#TRMPBF is a dual-channel voltage supervisor manufactured by Analog Devices Inc. It monitors two independent supply voltages and asserts a reset signal when inputs fall below or exceed configured thresholds. The device features an open-drain or open-collector active-low reset output with a minimum reset timeout of 140ms. It operates within a temperature range of 0°C to 70°C and is housed in an 8-DFN (3x2) surface-mount package.

Supervisors Feature Summary

• Dual-channel voltage monitoring capability for independent supply lines
• Configurable threshold combinations for under-voltage and over-voltage detection
• Active-low reset output with configurable open-drain or open-collector topology

Supervisors Applications

• Multi-rail industrial control systems requiring simultaneous voltage supervision
• Embedded computing platforms needing reliable power-on reset sequencing
• Automotive electronics monitoring critical logic supply rails

Supervisors Procurement Notes

Verify the specific suffix HDDB against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the operating temperature range of 0°C to 70°C aligns with your environmental specifications. Confirm compatibility with your system's voltage levels before integration.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in a compact footprint. The 8-DFN package suits space-constrained designs. Verify that the available threshold combinations cover your specific voltage monitoring needs without external resistors.

Supervisors Part Context

This part belongs to the LTC2905 series of precision voltage supervisors from Analog Devices. It shares architectural similarities with the LTC2904 but offers dual-channel functionality. The series is designed for applications requiring accurate power management and system reliability through continuous voltage supervision.

Supervisors Replacement Considerations

The LTC2905CDDB#TRMPBF is a documented variant within the same family, differing primarily in temperature grade and threshold options. Verify electrical parameters and package compatibility before substitution.
