This document introduces the features and characteristics of MCP201 products, including supported baud rates, power supply voltage range, working temperature range, interface standards, etc.
The MCP201 is a LIN transceiver with an on‑board low‑dropout 5 V regulator, supporting baud rates up to 20 kbaud and a wide supply range of 6 V to 18 V. It offers protection against 40 V load‑dump transients, reverse‑battery connections, and includes thermal shutdown and short‑circuit protection.
The device provides a half‑duplex, bidirectional interface between a microcontroller and a LIN bus, with configurable CS/WAKE control, multiple operational modes (Power‑down, Ready, Ready1, Operation), and a pinout that includes RXD, TXD, VREG, LIN, VBAT, FAULT/SLPS, and CS/WAKE. Typical applications and circuit examples are shown, along with detailed electrical specifications.
| Supply voltage range | 6.0 V – 18.0 V |
|---|---|
| Maximum input voltage | 30 V |
| Output voltage (regulator) | 5 V ±5 % |
| Maximum regulator output current | 50 mA |
| LIN bus drive current | 40 mA – 200 mA |
| Operating temperature range | -40 °C to +125 °C |
| Load‑dump protection | Up to 40 V |
| Number of LIN nodes supported | 1 master + up to 16 slaves |
The on‑board regulator provides a 5 V output with a tolerance of ±5 %.
The LIN specification allows one master and up to 16 slave nodes on the bus.
The device is protected against load‑dump transients up to 40 V.
