MCP131X/2X is a voltage supervisor device designed to keep a microcontroller in Reset until the system voltage has reached and stabilized at the proper level for reliable system operation.
The MCP131X/2X family are voltage supervisor devices that keep a microcontroller in reset until the supply voltage reaches a safe level. The document provides detailed electrical specifications, pin functions, and timing characteristics for each device variant.
Key features include low supply current, selectable trip points, multiple reset output options, and wide operating temperature and voltage ranges. The data sheet also covers code‑protection information and compliance statements.
| Low supply current | 1 pA typ., 10 µA max. |
|---|---|
| Operating voltage range | 1.0 V to 5.5 V |
| Temperature range (trip points 2.0‑2.4 V) | -40 °C to +85 °C |
| Temperature range (trip points >2.5 V) | -40 °C to +125 °C |
| RST low‑level output voltage (push‑pull) | 0.3 V |
| Input leakage current (MR and WDI pins) | 0.003 µA |
The devices draw as little as 1 pA typical, with a maximum of 10 µA.
They operate from 1.0 V up to 5.5 V supply voltage.
The devices are rated from –40 °C to +85 °C for lower trip points and up to +125 °C for higher trip points.
