Half-duplex Enhanced RS-485 Interface Chip Compatible With Traditional 485 Chip

 SCM3401A is a half-duplex enhanced transceiver designed for RS-485 data bus networks. Powered by 5V supply, the SCM3401A is fully compliant with TIA/EIA-485A standard and is suitable for data transmission of up to 1Mbps. Receivers have exceptionally high input impedance, which places only 1/8 of the standard load on a shared bus and up to 256 transceivers.

      SCM3401A's pin and performance are compatible with traditional IC, the reliability design of A, B pin is emphasized, including driver output over current protection and enhanced ESD design. The ESD protection level of A, B pin can be up to 15KV (Human Body Model). 

 

Features:

▶ 5.0V Single Supply Operation

▶ Baud Rate Up to 1Mbps

▶ 1/8 Unit Load-Up to 256 Nodes on a Bus

▶ Low Quiescent Power

   -0.3mA Active Mode

   -50nA Shutdown Mode

▶ Bus-Pin ESD Protection Up to 15KV

▶ Driver short circuit protection

Current-mode PWM Controller Integrated Circuit SCM1733ASA with 75mW Standby Consumption And 650V Power MOS

图片
  Introduction of   current mode pwm controller  SCM1733ASA   In order to achieve wider application range and lower price requirements, MORNSUN launched a new current-mode PWM controller SCM1733ASA applied to small and medium-power flyback   AC/DC converter    with ultra-low standby consumption of ＜ 75mW, a maximum output power of 20W, built-in high-voltage MOS and better price-performance. It features low starting current and working currently to achieve reliable start-up and achieving low consumptions.   When the AC/DC integrated circuit (IC) is fully loaded, the PWM switching frequency is fixed; after the load is reduced, the green mode is entered, and the switching frequency will step down; during no-load and light load, it will switch the intermittent mode to reduce consumptions. Multiple control modes also can provide soft-start control that reduces MOS stress and frequency jitter control to obtain good EMI. The frequency of intermittent mode is higher than 22KHz without audio no

SOIC-16 package isolated CAN/485 transceiver (R5 Bus IC)

图片
  Based on the IC integration requirement, Mornsun switching power supply factory   launched its SOIC package isolated Bus transceiver products, also called R5 Bus IC, this May.   Advantages:   1 ） Integrated power solution with superior performance R5 bus IC integrates power supply and digital isolation in circuit design to achieve power supply isolation and signal isolation. Take TDA51SCANHC and TDA51S-41HC as examples: only 5V voltage input is requested, and up to 110 nodes of nanosecond CAN bus signal transmission can be easily achieved at 1M frequency.   2 ） High reliability design, withstand voltage up to 5000Vrms R5 bus ICs are designed according to industry standards, taking TDA51SCANHC and TDA51S-41HC as examples, the products meet the requirements of ISO11898-2 standard, meanwhile, based on the requirements of UL1577 standard, the isolation voltage is up to 5000Vrms and CMTI is up to 150kV/us. The product integrates a variety of protections such as short-circuit protection, o
