MCP201
LIN Transceiver with Voltage Regulator
Features
• Supports baud rates up to 20 Kbaud
• 40V load dump protected
• Wide supply voltage, 6.0 – 18.0V, continuous
- Maximum input voltage of 30V
• Extended Temperature Range: -40°C to +125°C
• Interface to standard USARTs
• Compatible with LIN Spec 1.3
• Local Interconnect Network (LIN) Line pin:
- Internal pull-up resistor and diode
- Protected against ground shorts (LIN pin to
ground)
- Protected against LIN pin loss of ground
- High current drive, 40 mA ≤ IOL ≤ 200 mA
• Automatic thermal shutdown
• On-board Voltage Regulator:
- Output voltage of 5V with ±5% tolerances
over temperature range
- Maximum output current of 50 mA
- Able to drive an external series-pass
transistor for increased current supply
capability
- Internal thermal overload protection
- Internal short-circuit current limit
- External components limited to filter capacitor
only and load capacitor
