Frequently Asked Questions
What supply voltage range does the TCM811TERCTR supervise, and what reset threshold does it use?
The TCM811TERCTR is designed to supervise 3.3 V or 5 V supply rails depending on the selected threshold variant, with a fixed reset threshold typically within ±2% accuracy. It asserts an active-low reset output when the monitored voltage drops below the programmed threshold, ensuring safe system restart during brownout conditions.
Which embedded designs benefit most from the TCM811TERCTR single-channel supervisor?
Microcontroller-based boards operating at 3.3 V, battery-powered IoT nodes, and industrial control modules all benefit from the TCM811TERCTR. It provides a single supervised reset channel with a minimum reset pulse width, preventing false starts during slow power ramp-up scenarios common in capacitive bulk supply designs with 10 µF or larger filter capacitors.
How does the SOT-143 package of the TCM811TERCTR compare to larger supervisor packages in board area?
The SOT-143 4-pin package occupies roughly 1.6 mm x 1.6 mm of PCB footprint, which is significantly smaller than SOT-23-5 or SOT-23-6 supervisor packages. This makes the TCM811TERCTR suitable for high-density layouts where saving 2 mm² or more per supervisory device is meaningful, such as wearables or compact industrial sensors running off a 3.3 V rail.
Is the TCM811TERCTR available in tape-and-reel packaging for automated SMT assembly?
Yes, the TERCTR suffix indicates tape-and-reel packaging on a standard 7-inch reel, typically containing 3000 units. This format is compatible with pick-and-place SMT equipment operating at standard component placement speeds, reducing manual handling for medium-to-high volume production runs of boards using the 4-pin SOT-143 footprint.
