MCP131X/2X is a series of voltage supervisor devices introduced by Microchip Technology Inc., designed to keep a microcontroller in Reset until the system voltage has reached and stabilized at the proper level for reliable system operation. This family of devices also offers a Watchdog Timer to monitor system operation and a Manual Reset input.
The MCP131X/2X family of voltage supervisor devices monitors system voltage and provides a reset signal until the voltage reaches a stable level. The devices also include a watchdog timer and manual reset input, with selectable trip points and reset‑delay options.
The datasheet lists detailed electrical specifications, package options, and timing parameters for each part number (MCP1316, MCP1317, MCP1318, MCP1319, MCP1320‑22). It also describes reset‑output configurations, temperature ranges, and code‑protection features.
| Operating Voltage Range | 1.0 V to 5.5 V |
|---|---|
| Temperature Range | -40°C to +125°C |
| Supply Current (typical) | 5 µA |
| Reset Output Options | Push‑Pull (active‑high or active‑low) and Open‑Drain |
The devices operate from 1.0 V up to 5.5 V.
Both push‑pull (active‑high or active‑low) and open‑drain (with internal or external pull‑up) outputs are supported.
The reset‑delay can be set to 1.4 ms, 30 ms, 200 ms, or 1.6 s (typical).
They are rated for operation from –40 °C to +125 °C.
