Microchip MCP202X LIN Transceiver
The MCP202X family provides a LIN transceiver with an on‑chip voltage regulator (5 V or 3.3 V, 50 mA). It supports LIN bus specifications 1.3‑2.1, SAE J2602, and baud rates up to 20 kbaud (LIN) or 50 kbaud (ISO‑9141). The device operates from a wide supply range (6 V‑18 V continuous, up to 30 V input) and includes load‑dump, short‑circuit, thermal shutdown, ESD, and ground‑loss protection.
The document describes pin assignments, operational modes (Power‑On‑Reset, Power‑Down, Ready, Operation, Transmitter‑Off), typical application circuits, and mechanical package options (DFN‑8, PDIP‑8, SOIC‑8, PDIP‑14, TSSOP‑14). It also provides protection guidelines and regulatory compliance notes.
