Key Features
- Fixed 3 V supervisory threshold with active-low open-drain reset output directly compatible with 3.3 V microcontroller RESET pins without external level shifting
- Single-channel 1-function design minimizes BOM complexity for simple power-on reset applications in microcontroller and DSP systems
- SOT-143 4-pin package occupies less than 5 mm² of PCB area, enabling ultra-compact reset supervision in space-constrained wearables and IoT modules
Applications
The MIC6315-30D4UY-TR is a fixed-threshold voltage supervisor used to generate a clean power-on reset signal for microcontrollers, FPGAs, and DSPs operating on a 3 V or 3.3 V supply rail. It asserts a clean active-low reset during power-up and holds it asserted whenever the supply voltage drops below the 3 V supervisory threshold, preventing corrupted code execution during brownout conditions. Its tiny SOT-143 package and single-supply operation make it ideal for IoT sensor nodes, wearable electronics, and battery-powered embedded devices where PCB space and power budget are tightly constrained.

Frequently Asked Questions
At what supply voltage does MIC6315-30D4UY-TR assert its reset output, and how does this protect microcontrollers during power-up?
The MIC6315-30D4UY-TR asserts the active-low reset output whenever the supply voltage is below approximately 3 V. During power-up, this holds the microcontroller in reset until the supply stabilizes above 3 V, preventing the processor from executing code with an under-voltage supply that could corrupt flash memory writes or cause undefined register states during initialization.
How does the open-drain reset output of MIC6315-30D4UY-TR benefit designs with multiple microcontrollers sharing a common reset bus?
The open-drain output of the MIC6315-30D4UY-TR allows multiple devices with open-drain reset pins to be wire-OR connected on a shared reset line, so any single device pulling low asserts reset for the entire system. This eliminates additional reset buffer ICs when synchronizing power-on reset across 2 to 4 microcontrollers or memory devices, saving BOM cost and approximately 10 mm² of PCB area per omitted buffer.
Why choose MIC6315-30D4UY-TR over a simple RC reset circuit for 3 V microcontroller systems?
A simple RC reset circuit has a time constant determined by capacitor and resistor tolerances, which can vary by 20% or more, causing reset pulses shorter than 1 ms in worst-case corners. The MIC6315-30D4UY-TR provides a precisely trimmed 3 V threshold with a defined minimum reset pulse width, typically 140 ms, ensuring reliable processor initialization across the operating temperature range of -40°C to 125°C without component variation risk.
What package does MIC6315-30D4UY-TR use and how does it compare to SOT-23 supervisors in board area?
The MIC6315-30D4UY-TR is housed in a 4-pin SOT-143 package with a footprint of approximately 1.6 mm x 1.6 mm, occupying less than 3 mm² of PCB area. Compared to standard SOT-23-3 packages at about 3 mm x 1.75 mm, the SOT-143 is roughly 50% smaller in one dimension, making it ideal for wearable and IoT designs where every square millimeter of board space impacts product dimensions and weight.
