DS22018F-page 1 MCP2021/2/1P/2P Features • The MCP2021/2/1P/2P are compliant with LIN Bus Specifications 1.3, 2.0, and 2.1 and are compliant to SAE J2602 • Support Baud Rates up to 20 Kbaud with LIN-compatible output driver • 43V Load dump protected • Very low EMI meets stringent OEM requirements • Wide supply voltage, 6.0V - 18.0V continuous: - Maximum input voltage of 30V • Extended Temperature Range: -40 to +125°C • Interface to PIC EUSART and standard USARTs • Local Interconnect Network (LIN) bus pin: - Internal pull-up resistor and diode - Protected against ground shorts - Protected against loss of ground - High current drive • Automatic thermal shutdown • On-Chip Voltage Regulator: - Output voltage of 5.0V with tolerances of ±3% overtemperature range - Available with alternate output voltage of 3.3V with tolerances of ±3% overtemperature range - Maximum continuous input voltage of 30V - Internal thermal overload protection - Internal short circuit current limit - External components limited to filter capacitor only and load capacitor • Two low-power modes: - Receiver on, Transmitter off, voltage regulator on ( ≅ 85 µA) - Receiver monitoring bus, Transmitter off, voltage regulator off ( ≅ 16 µA) Description The MCP2021/2/1P/2P provides a bidirectional, half- duplex communication physical interface to automotive and industrial LIN systems that meets the LIN bus specification Revision 2.0. The devices incorporate a voltage regulator with 5V at 50 mA or 3.3V at 50 mA regulated power-supply outputs. The regulator is short-circuit protected, and is protected by an internal thermal shutdown circuit. The device has been specifically designed to operate in the automotive operating environment and will survive all specified transient conditions while meeting all of the stringent quiescent current requirements. The MCP2021/2/1P/2P family of devices includes the following packages. 8-pin PDIP, DFN and SOIC packages: • MCP2021-330, LIN-compatible driver, 8-pin, 3.3V regulator, wake up on dominant level of LBUS • MCP2021-500, LIN-compatible driver, 8-pin, 5.0V regulator, wake up on dominant level of LBUS • MCP2021P-330, LIN-compatible driver, 8-pin, 3.3V regulator, wake up at falling edge of LBUS voltage • MCP2021P-500, LIN-compatible driver, 8-pin, 5.0V regulator, wake up at falling edge of LBUS voltage 14-pin PDIP, TSSOP and SOIC packages with RESET output: • MCP2022-330, LIN-compatible driver, 14-pin, 3.3V regulator, RESET output, wake up on domi- nant level of LBUS • MCP2022-500, LIN-compatible driver, 14-pin, 5.0V regulator, RESET output, wake up on domi- nant level of LBUS • MCP2022P-330, LIN-compatible driver, 14-pin, 3.3V regulator, RESET output, wake up at falling edge of LBUS voltage • MCP2022P-500, LIN-compatible driver, 14-pin, 5.0V regulator, RESET output, wake up at falling edge of LBUS voltage LIN Transceiver with Voltage Regulator |
