BIN1021S-C

BIN1021-C is a Local Interconnect Network (LIN) transceiver. LIN is a low-speed UART communication protocol supporting automotive in-vehicle networks. The BIN1021-C controls the LIN bus state via the TXD pin with optimized slew rate and waveform shaping to minimize EME, and reports bus status through its open-drain RXD output pin. The BIN1021-C supports 12V applications through a wide input voltage range, along with a low-power sleep mode. The device supports wake-up from the LIN, WAKE_N, and SLP_N pins. Through the INH pin, the device can selectively enable various power supplies present at the node, thereby reducing battery current consumption at the system level. The BIN1021-C integrates resistors for slave node applications and ESD protection, reducing the number of external components in system applications. In the event of ground drift or supply voltage disconnection, the device prevents reverse current from flowing through LIN to the supply input. The BIN1021 is an interface device between a LIN protocol controller and the physical bus, suitable for trucks, buses, passenger vehicles, and industrial control applications, with a data transfer rate of up to 20kbps. The BIN1021 receives the transmit data stream from the protocol controller at the TXD input and converts it into bus signals with optimized slew rate and waveform shaping; input data on the LIN bus is output to an external MCU via the receiver's RXD port. This device is compatible with the LIN 2.x/ISO 17987-4:2016/SAE J2602 standard. The LIN bus features output short-circuit protection, and when overheating occurs, the internal over-temperature protection circuit sets the bus to a high-impedance state.
