Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The MCT8316Z0RQRGFRQ1 provides a single-chip, code-free induction ladder solution for customers driving 12-V brushless DC motors in automobiles. The integration of three 1/2-H bridges with 40 V absolute maximum capability and ultra-low RDS(ON) of 95 mOhms (HV-side and LV-side combined) enables high power drive capability. Current detection uses an integrated current detection function, eliminating the need for external detection resistors. The power management functions of the adjustable buck regulator and LDO generate the necessary voltage rails for the device and can power external circuits.

The MCT8316Z0RQRGFRQ1 implements inductive trapezoidal control in a fixed-function state machine, thus eliminating the need for an external microcontroller to rotate a brushless DC motor. The device integrates three analogue Hall comparators for position sensing to implement inductive ladder brushless DC motor control. The control scheme is highly configurable via hardware pins or register settings, including motor current limit behaviour and fault response. Speed can be controlled via the PWM input.

• 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.
