TLE9872QTW40: MOTIX™ Three-Phase Bridge Driver IC, TQFP-48

Basic Information:

Model: TLE9872QTW40

Package: TQFP-48

Type: MOTIX™ Three-Phase Bridge Driver IC

The TLE9872QTW40 is a single-chip, 3-phase motor driver that integrates the industry-standard Arm® Cortex®-M3 core, enabling advanced motor control algorithms such as field-oriented control. It includes six fully integrated NFET drivers optimised to drive 3-phase motors with six external power NFETs, a charge pump for low-voltage operation and programmable currents, and current ramp control to optimise EMC. The peripheral set includes a current sensor, a successive approximation ADC synchronised with the capture and compare unit for PWM control, and a 16-bit timer. In addition, a LIN transceiver and multiple general-purpose input/output interfaces are integrated for communication with devices. It includes an on-chip linear regulator to power external loads.

TLE9872QTW40 Product Features:

Six current-programmable drivers with N-channel MOSFET charge pumps

Integrated LIN transceiver, compatible with LIN 2.2 and SAEJ2602

Two full-duplex serial interfaces (UARTs) with LIN support

Two synchronous serial channels (SSC)

On-chip OSC and PLL for clock generation

One high-voltage monitor input with wake-up function

High-speed operational amplifiers for sensing motor currents via shunts

Measurement unit:

8-bit ADC module with 10 multiplexed inputs

10-bit ADC module with 8 multiplexed inputs, 5 external analogue inputs

On-chip temperature and battery voltage measurement unit

Temperature shutdown enhancements to support operation up to Tjmax = 175 °C

Individually programmable window watchdog

5V/1.5V internal supply

External supply (VDDEXT): 5V+/-2% @ 20mA

• 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.
