LTC2911CDDB-1#TRPBF

Supervisors Overview

The LTC2911CDDB-1#TRPBF is a multi-supply voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 5.5V and draws a typical quiescent current of 40µA. The device features three independent voltage monitoring channels with fixed thresholds for two channels and one adjustable threshold for the third. It provides an active-low reset output with a selectable timeout period ranging from 1ms to 1000ms. The component is housed in an 8-lead DFN package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Provides simultaneous monitoring of three distinct power rails using dedicated input pins.
• Features a configurable reset timeout period allowing customization of delay duration.
• Includes an open-drain or push-pull reset output compatible with various logic families.
• Operates with low quiescent current consumption suitable for battery-powered applications.

Supervisors Applications

• Multi-rail power sequencing in embedded systems
• Voltage supervision for microprocessors and FPGAs
• Battery-operated portable devices requiring efficient power management

Supervisors Procurement Notes

Verify the specific suffix codes against official datasheets to confirm pinout and threshold configurations. Ensure compatibility with your system's voltage levels and reset timing requirements before integration. Check for RoHS compliance status as per manufacturer declarations. Confirm availability through authorized distributors due to potential supply constraints.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with minimal standby current. Consider the adjustable threshold channel for flexible monitoring needs. Evaluate the required reset timeout duration against system startup specifications. Ensure the operating temperature range meets environmental conditions.

Supervisors Part Context

This part belongs to the LTC2911 series of supervisory circuits designed for compact, low-power applications. It complements other PMIC solutions by providing precise voltage monitoring without complex external components. The DFN package facilitates space-constrained PCB layouts.

Supervisors Replacement Considerations

Direct substitutes include other parts from the LTC2911 family with different suffixes indicating varied thresholds or packages. Cross-reference with similar multi-channel supervisors from Analog Devices ensuring matching voltage ranges and output types.
