概要
Description
MIC37100-2.5WS is a fixed-threshold voltage supervisor (reset generator) from Micrel/Microchip. It continuously monitors the supply voltage and asserts a reset when Vcc falls below the 2.5 V threshold. When the supply stabilizes above the threshold, the device releases the reset after its built-in power‑on reset delay, ensuring a clean start for microcontrollers or processors.
Key points:
- Fixed 2.5 V threshold (provides brown‑out/power‑on reset protection).
- Generates a reset signal to ensure proper microcontroller startup.
- Typically features low quiescent current and a compact WS package for space-constrained boards.
- Suitable for supervising 2.5 V cores or rails derived from higher voltages, and for safe‑boot/power‑on sequencing.
Typical applications include microcontroller supervision, brown‑out protection, and reliable reset timing in embedded systems. For exact electrical specs, timing, polarity of the reset output, and package details, refer to the datasheet.
