- Factory-set voltage threshold with ±2 % typical accuracy ensures reliable brownout detection without external resistors or trim
- 5-pin SOT-23 package with active-high or active-low reset output fits the tightest PCB layouts in portable and embedded designs
- Wide operating supply range compatible with 1.8 V, 3.3 V, and 5 V systems for versatile multi-rail supervision
Applications
MIC2779L-1YM5 TR is used to supervise power rails in microcontroller-based systems, asserting a clean reset signal during startup, brownout, or power-fail conditions to prevent erratic firmware execution. It is well suited for battery-powered IoT nodes, industrial control boards, and automotive accessory modules where glitch-free power sequencing is critical. The SOT-23 footprint keeps solution size minimal in space-constrained wearable and handheld products.

Frequently Asked Questions
What voltage threshold accuracy does MIC2779L-1YM5 TR provide for brownout detection?
MIC2779L-1YM5 TR offers a factory-preset voltage threshold with approximately ±2 % accuracy, allowing it to detect brownout conditions reliably without external calibration resistors. This tight tolerance ensures the reset signal asserts and deasserts at consistent voltages across the full operating temperature range, protecting microcontrollers from executing code under under-voltage conditions.
In which board form factors can MIC2779L-1YM5 TR be used given its package size?
MIC2779L-1YM5 TR is housed in a 5-pin SOT-23 package, one of the smallest surface-mount IC packages available, with a footprint under 3 mm × 3 mm. This makes it suitable for wearables, IoT sensor nodes, handheld instruments, and any design where PCB real estate is limited but reliable voltage monitoring across a 1.8 V to 5 V range is still required.
How does MIC2779L-1YM5 TR compare to a discrete reset circuit using a resistor divider and comparator?
A discrete solution with a resistor divider and comparator requires at least 3–5 components and a separate hysteresis network, occupying several square centimetres of board space. MIC2779L-1YM5 TR integrates the threshold reference, hysteresis, and output driver into a single 5-pin SOT-23 chip less than 3 mm × 3 mm, reducing component count by approximately 4 parts and simplifying BOM management for high-volume production runs.
Is MIC2779L-1YM5 TR supplied in tape-and-reel format for automated assembly?
Yes, the TR suffix confirms MIC2779L-1YM5 TR ships in standard tape-and-reel format compatible with 8 mm carrier tape and pick-and-place machines. Reel quantities typically hold 3000 units, reducing manual handling in high-volume SMT assembly lines and enabling uninterrupted automated placement of the 5-pin SOT-23 package.
