Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The AMC21C12DENR is an isolated window comparator with a short response time. The open-drain output is galvanically isolated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. The isolation barrier supports a working voltage up to 200 VRMS or 280 VDC and transient over voltages of up to 570 VRMS or 800 VDC.

Features

• Wide high-side supply range: 3 V to 27 V

• Low-side supply range: 2.7 V to 5.5 V

• Adjustable threshold:

– Window-comparator mode: ±20 mV to ±300 mV

– Positive-comparator mode: 600 mV to 2.7 V

• Reference for threshold adjustment: 100 μA, ±1%

• Trip threshold error: ±1% (max) at 250 mV

• Open-drain output with optional latch mode

• Propagation delay: 280 ns (typ)

• High CMTI: 55 V/ns (min)

• Functional Isolation:

– Working voltage: 200 VRMS, 280 VDC

– Transient overvoltage (60 s): 570 VRMS, 800VDC

• Small, 0.65-mm pitch, leadless package with 1-mm creepage and clearance

• Fully specified over the extended industrial temperature range: –40°C to +125°C

Applications

• Overcurrent or overvoltage detection in:

– Telecom power supplies

– Analog I/O modules

– Motor drives

– Frequency inverters

• 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?
