Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC2975IUP is a 4-channel power system manager for sequencing, trimming (servoing), margining, monitoring, managing faults, providing remote sampling, and creating fault logs.PMBus commands support power sequencing, precision point-of-load voltage regulation, and margining.The DAC employs a proprietary softwire algorithm to maximise power supply perturbation suppression. Monitoring features include overcurrent and undercurrent, voltage, and temperature thresholds for the four power output channels, as well as overvoltage and undervoltage thresholds on a single power input channel. Programmable fault response can deactivate the power supply with the option to "perform a retry after a fault is detected". Faults that cause the power supply to deactivate automatically trigger the black box EEPROM memory to record the fault status and associated remote samples. An internal 16-bit ADC monitors four output voltages, four output currents, four external temperatures, input voltages and currents, and chip temperature. In addition, input power, energy and output power are calculated. A programmable watchdog timer monitors the microprocessor operation for stall conditions and resets the microprocessor if necessary. A single-wire bus enables power synchronisation across multiple LTC power system management (PSM) devices. The configuration EEPROM supports autonomous operation and does not require additional software.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
