TLE9877QXW40XUMA2

Overview

The TLE9877QXW40XUMA2 is a single-chip three-phase motor driver from Infineon's TLE987x family, designed for automotive applications. It integrates an ARM Cortex-M3 core operating at up to 40 MHz with 64 kB Flash and 6 kB RAM. The device features six integrated NFET drivers optimized for external power MOSFETs, a charge pump for low-voltage operation, and programmable current control. Key peripherals include a LIN transceiver, a high-speed operational amplifier for current sensing, and a 10-bit ADC synchronized with PWM capture/compare units. It operates on a single supply of 5.5 V to 27 V within an extended temperature range of -40°C to +175°C in a VQFN-48 package.

• Operates on a single supply voltage of 5.5 V to 27 V with an extended junction temperature range up to 175°C.

Applications

• Brushless DC (BLDC) motor control for automotive cooling fans and HVAC blowers.
• Water pump and fuel pump drive systems.
• Sensor-less and sensor-based BLDC motor applications controlled via LIN or PWM.

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before procurement planning. Confirm that the specific suffix XUMA2 corresponds to the required tape-and-reel packaging format. Ensure design timelines account for potential end-of-life constraints associated with this lifecycle stage.

Selection Notes

Select this part for applications requiring integrated motor drive capabilities alongside LIN communication in a compact VQFN-48 footprint. Verify compatibility with external power MOSFETs and ensure the system voltage remains within the 5.5 V to 27 V range. Consider the NRND status if long-term production availability is a critical requirement for the target application.

Part Context

This component belongs to the Infineon MOTIX™ TLE987x series of embedded power ICs. It is specifically engineered for automotive-grade reliability, meeting AEC-Q100 standards. The device consolidates microcontroller, power driver, and communication interfaces into a single solution to reduce bill-of-materials count and board space.

Replacement Considerations

Consult official Infineon documentation for qualified alternatives within the TLE987x family. Potential substitutes may include variants with different memory sizes or package types, such as the TLE9877QXA40 series, subject to pinout and functional compatibility verification.
