What are the key features of MCP2003BT-E/SN?
- Single LIN 2.x transceiver providing physical layer interface between a microcontroller UART and the LIN bus up to 20 kbps
- Integrated slew-rate control and bus fault protection for robust automotive and industrial network designs
- Standard SOIC-8 package with 1.27 mm pitch enables easy PCB assembly and hand-soldering in prototype builds
What is MCP2003BT-E/SN used for?
MCP2003BT-E/SN serves as the physical layer interface in LIN bus networks for automotive body electronics including seat control, mirror adjustment, window lifters, and lighting modules communicating at up to 20 kbps. In industrial automation, it connects microcontroller UARTs to LIN-based sensor clusters and actuator networks where low-speed serial communication over a single wire reduces wiring harness complexity. The SOIC-8 package simplifies integration alongside PIC or AVR MCUs on slave node PCBs.

Frequently Asked Questions
What maximum data rate does MCP2003BT-E/SN support on a LIN bus network?
MCP2003BT-E/SN supports LIN bus data rates up to 20 kbps as specified by LIN 2.x standards. At 20 kbps the transceiver provides a single-wire half-duplex interface between the microcontroller UART and the bus, with integrated slew-rate control that keeps electromagnetic emissions within automotive EMC limits even across cable lengths of several metres typical in vehicle harnesses.
How does MCP2003BT-E/SN protect the LIN bus node from wiring faults in automotive environments?
MCP2003BT-E/SN incorporates bus fault protection features that tolerate shorts to battery voltage (up to +40 V load dump) and shorts to ground on the LIN pin without damaging the device. This protection is critical in automotive harnesses where wiring faults during assembly or operation can expose bus nodes to transient voltages well above the 12 V nominal supply, saving costly ECU replacement in the field.
For a LIN slave node design, when should an engineer choose MCP2003BT-E/SN over integrating LIN PHY inside an MCU?
When using a general-purpose PIC or AVR microcontroller that lacks a built-in LIN PHY, MCP2003BT-E/SN adds full LIN 2.x physical layer compliance via a standard UART interface at the cost of only 1 additional SOIC-8 IC and minimal passives. Integrated LIN PHY MCUs typically cost 20–50 % more per unit; for high-volume slave nodes such as window switches or mirror actuators where hundreds of thousands of units are built annually, the external transceiver approach can reduce BOM cost despite the added component.
