Supervisors datasheet and documents for LTC2919CDDB-2.5#TRMPBF
Supervisors Overview
The LTC2919CDDB-2.5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.7V to 6V and consumes only 50µA of quiescent current. The device features three independent monitoring channels with open-drain outputs, supporting under-voltage, over-voltage, and negative voltage supervision. It utilizes a 10-WFDFN package with exposed pad for surface-mount installation.
Supervisors Feature Summary
- Provides simultaneous monitoring of up to three independent voltage inputs
- Features adjustable threshold voltages for customized supervision requirements
- Delivers low-power operation suitable for battery-supplied systems
Supervisors Applications
- Portable electronic devices requiring multi-rail power supervision
- Industrial control systems needing precise voltage tracking
- Telecommunications equipment monitoring critical power rails
Supervisors Procurement Notes
Verify the specific suffix #TRMPBF indicates tape-and-reel packaging configuration. Confirm the CDDB variant meets commercial temperature specifications. Ensure compatibility with existing PCB footprints for the 10-WFDFN package. Cross-reference datasheet revisions for any recent manufacturing changes.
Supervisors Selection Notes
Select this component when multiple voltage rails require individual supervision within a compact footprint. The adjustable thresholds allow flexibility for various system architectures. Consider the 50µA quiescent current impact on overall system efficiency during active and standby modes.
Supervisors Part Context
This part belongs to the LTC2919 series of precision supervisors. It shares functional similarities with the LTC2912 and LTC2915 but offers higher channel density. The family focuses on accurate voltage monitoring without manual reset capabilities or watchdog timers.
Supervisors Replacement Considerations
LTC2919CDDB-5#TRPBF is listed as a parameter-equivalent alternative in public distributor records.
