The LM74700-Q1 is an automotive AEC Q100
qualified ideal diode controller which operates in
conjunction with an external N-channel MOSFET as
an ideal diode rectifier for low loss reverse polarity
protection with a 20-mV forward voltage drop. The
wide supply input range of 3.2 V to 65 V allows control
of many popular DC bus voltages such as 12-V, 24-V
and 48-V automotive battery systems. The 3.2-V input
voltage support is particularly well suited for severe
cold crank requirements in automotive systems. The
device can withstand and protect the loads from
negative supply voltages down to –65 V.
The device controls the GATE of the MOSFET to
regulate the forward voltage drop at 20 mV. The
regulation scheme enables graceful turn off of the
MOSFET during a reverse current event and ensures
zero DC reverse current flow. Fast response (< 0.75
μs) to Reverse Current Blocking makes the device
suitable for systems with output voltage holdup
requirements during ISO7637 pulse testing as well as
power fail and input micro-short conditions.
The LM74700-Q1 controller provides a charge pump
gate drive for an external N-channel MOSFET. The
high voltage rating of LM74700-Q1 helps to simplify
the system designs for automotive ISO7637
protection. With the enable pin low, the controller is off
and draws approximately 1 μA of current.

All the products will packing in anti-staticbag. Ship with ESD antistatic protection.
Outside ESD packing’s lable will use ourcompany’s information: Part Mumber, Brand and Quantity.
We will inspect all the goods before shipment,ensure all the products at good condition and ensure the parts are new originalmatch datasheet.
After all the goods are ensure no problems afterpacking, we will packing safely and send by global express. It exhibitsexcellent puncture and tear resistance along with good seal integrity.
1.We provide 90 days warranty.
2.If some of the items you received aren't of perfect quality, we would resiponsibly arrange your refund or replacement. But the items must remain their orginal condition.
Q: How does Perceptive guarantee that MF10CN is the original manufacturer or agent of MAX?
We have a professional business development department to strictly test and verify the qualifications of MAX original manufacturers and agents. All MAX suppliers must pass the qualification review before they can publish their MF10CN devices; we pay more attention to the channels and quality of MF10CN products than any other customer. We strictly implement supplier audits, so you can purchase with confidence.
Q: How to find the detailed information of MF10CN chips? Including MAX original factory information, Active Filter application, MF10CN pictures?
You can use Perceptive's intelligent search engine, or filter by Active Filter category, or find it through MAX brand manufacturer page.
Q: Are the MAX's MF10CN price and stock displayed on the platform accurate?
The MAX's inventory fluctuates greatly and cannot be updated in time, it will be updated periodically within 24 hours. After submitting an order for MF10CN, it is recommended to confirm the order with Perceptive salesperson or online customer service before payment.
Q: What forms of payment can I use in Perceptive?
TT Bank, Paypal, Credit Card, Western Union, and Escrow is all acceptable.
Q: How is the shipping arranged and track my package?

Once your order has been processed for shipment, our sales will send you an e-mail advising you of the shipping status and tracking number.
Note: It may take up to 24 hours before carriers will display tracking information. In normal conditions, Express delivery needs 3-5 days, Registered Mail needs 25-60 days.
Q: What is the process for returns or replacement of MF10CN?
All goods will implement Pre-Shipment Inspection (PSI), selected at random from all batches of your order to do a systematic inspection before arranging the shipment. If there is something wrong with the MF10CN we delivered, we will accept the replacement or return of the MF10CN only when all of the below conditions are fulfilled:
(1)Such as a deficiency in quantity, delivery of wrong items, and apparent external defects (breakage and rust, etc.), and we acknowledge such problems.
(2)We are informed of the defect described above within 90 days after the delivery of MF10CN.
(3)The MF10CN is unused and only in the original unpacked packaging.
Two processes to return the products:
(1)Inform us within 90 days
(2)Obtain Requesting Return Authorizations
