LIN Overview  Local Interconnect Network (LIN) is a low-cost serial communication network defined for distributed electronic systems in vehicles used to control such systems. LIN complements other automotive multiplex networks like Controller Area Network (CAN) for applications with moderate requirements for bandwidth, performance, or fault tolerance.  By creating a basic serial network between actuators, sensors, switches, and ECUs, LIN significantly reduces design costs for automakers, with typical applications to be found in lighting, doors, windows, power seats, air conditioning, and sensors.  TPT102xQ Series Introduction  TPT102xQ Series LIN transceivers meet ISO 17987-4, SAE J2602, and LIN2.0, LIN2.1, LIN2.2, and LIN2.2A physical layer standards, and support data speeds of up to 20 kbps.  These transceivers feature a wide power supply input range, ultra-low power standby and sleep modes, ±45-V bus fault tolerance on the LIN bus side, support for LIN bus wake-up and local wake-up via pin control, and the INH pin on the TPT1021Q can control an external power supply to facilitate system-level power reduction.  The TPT102xQ Series of LIN transceivers offers comprehensive protection features with IEC ESD protection of ±8 kV, while the IEC ESD protection of the TPT1021Q is ±15 kV to enhance the reliability and robustness of the system and network.  The TPT1021Q, TPT1022Q, and TPT1024Q support single, dual, and quad LIN bus communication, respectively.  The TPT1022Q and TPT1024Q deliver dual and quad LIN in a compact package, reducing the board footprint required for system applications and allowing smaller system design.  3PEAK TPT1021Q Performance Comparison with Competitors  TPT102xQ Series Advantages  1: TPT1021Q IEC-61000-4-2 Features a Globally Leading ESD Capacity of ±15-kV  2: Wide Input Power Range of 5.5V–40V, Surpassing Equivalent Industry Products and Satisfying ISO7637 Transient Drop Test Conditions  3: Bus Slope Control to Optimize the LIN Transceiver's External Radiation Levels and Excellent EMI Capabilities  4: Ultra-Low Power Sleep Mode, with Power Use as Low as 5.9 μA in Sleep Mode  5: TXD Dominant Time-Out Protection to Prevent Prolonged Bus Occupation  6: Comprehensive Protection Mechanisms, Including Under-Voltage and Over-Temperature Protection  7: The DFN Package in the TPT102xQ Series Uses the Wettable Flank Process  This enhances solder joint visibility for AOI inspection and the reliability of the solder.

<span style='color:red'>3PEAK</span> Announces TPM2351x Series Isolated Gate Drivers with ±150-kV/μs CMTI!
  3PEAK (stock code: 688536), a semiconductor company focusing on the development of high-performance analog chips and embedded processors, has recently unveiled the TPM2351x series isolated gate drivers with ±150-kV/μs CMTI, which can be widely used in IGBTs, SiC MOSFETs, and other power devices.  Highlights of TPM2351x  Single-Channel Isolated Gate Driver Compatible with Optocoupler Input  Outputs 4.5-A Peak Source Current and 5-A Peak Sink Current  40-V Output Power Voltage  Input Stage with 6-V Polarity Reversal Voltage Handling Capability  70-ns Transfer Delay  25-ns Inter-Device Delay Matching  35-ns Pulse Width Distortion  5-kVrms Enhanced Isolation Level  Minimum Common-Mode Transient Immunity (CMTI) of ±150 kV/μs  WSOP Wide Package  Operating Temperature Range: –40°C to +125°C  Advantages of TPM2351x  Minimum CMTI: ±150 kV/μs  3PEAK TPM2351x series products can withstand Common-Mode Transient Immunity (CMTI) of ±150 kV/μs or more. Therefore, they are extensively used in IGBTs, SiC MOSFETs, and other power devices. The figure below shows the output waveform of TPM2351X at ±160-kV/μs CMT, which indicates that the output is not affected by high transient interference at the primary and secondary edges.  TPM23514M provides a built-in Miller clamp to reduce the risk of power device crosstalk under high-speed switching. The following figure uses a double-pulse experiment to compare the waveforms of the gate-source voltage (Vgs) of the power device before and after the Miller clamp is applied. Before the Miller clamp is applied, the voltage change (ΔV) of the high-side switch Vgs reaches 5 V during the turn-on transient of the low-side switch. After the Miller clamp is applied, the voltage change (ΔV) is reduced to 2 V, which greatly reduces the risk of crosstalk for the high-side switch.  Typical Application of TPM2351x Products  The TPM2351x series drivers support bipolar power supply and can effectively drive SiC MOSFETs, IGBTs, and other power devices. In addition, TPM23514M provides a built-in Miller clamp function, which can reduce the risk of power device mis-conductivity under high-speed switching.
