Frequently Asked Questions
How many supply channels does LTC2918CDDB-A1#TRMPBF monitor, and is the threshold fixed or adjustable?
The LTC2918CDDB-A1#TRMPBF monitors 1 supply channel with an adjustable threshold, allowing designers to set the undervoltage trip point using external resistors. This single adjustable-threshold architecture eliminates the need to stock multiple fixed-voltage reset IC variants, simplifying BOM management for designs with non-standard supply rails between 1V and 5V.
What reset output type does the LTC2918CDDB-A1#TRMPBF use, and how does it connect to a microcontroller reset pin?
The LTC2918CDDB-A1#TRMPBF provides an active-low, open-drain reset output that requires an external pull-up resistor, typically 10 kΩ to 100 kΩ, to the system supply voltage. This open-drain topology allows the reset line to be wire-OR'd with other reset sources or manual reset buttons, enabling flexible reset architecture in microcontroller and DSP-based embedded systems.
Is LTC2918CDDB-A1#TRMPBF qualified for automotive applications, and what package does it use?
Yes, the LTC2918CDDB-A1#TRMPBF carries automotive-grade qualification, making it suitable for ECU and body electronics applications subject to AEC-Q100 temperature and reliability standards. It is housed in a 10-pin DFN package with exposed pad measuring approximately 3x3 mm, providing a thermally efficient, compact footprint for automotive PCBs where board space is at a premium.
Does LTC2918CDDB-A1#TRMPBF include a manual reset input, and when is this feature useful?
Yes, the LTC2918CDDB-A1#TRMPBF includes a manual reset input (MNL RST: Y) that allows an external signal or button press to force the reset output active regardless of supply voltage status. This feature is valuable in automotive and industrial service tools that need to force a processor reset during diagnostics, firmware updates, or fault recovery without removing power from the monitored supply rail.
