Strengthening the link between the real and the digital worldTLE9868QXB20
TLE9868QXB20 offers high-performance and cost-optimization for wiper and comfort drives
The TLE9868QXB20 is part of the TLE986x product family. The TLE9868QXA20 is a single chip 2-Phase motor driver that integrates the industry standard Arm® Cortex®-M3 core, enabling the implementation of advanced motor control algorithms. It includes four fully integrated NFET drivers optimized to drive a 2-Phase motor via four external power NFETs, a charge pump enabling low voltage operation and programmable current along with current slope control for optimized EMC behavior. Its peripheral set includes a current sensor, a successive approximation ADC synchronized with the capture and compare unit for PWM control and 16-bit timers. Additionally, two differential 14-bit Sigma Delta ADCs are implemented for high precision sensor measurement. A LIN transceiver is also integrated to enable communication to the device along with a number of general purpose I/Os. It includes an on-chip linear voltage regulator to supply external loads.
It is a highly integrated automotive qualified device enabling cost and space efficient solutions for mechatronic DC motor drive applications such as wiper, sunroof and power window lift.

Additional Tools for Design-in
Embedded Power ICs provide a built-in boot strap loader (BSL) for programming the system-on-chip devices over the built-in LIN transceiver or UART. The uIO Stick acts as an interface between the TLE98xx device and a PC. It handles the BSL protocols as well as the physical layers. A PC application (uIO BSL Tool) provides access to all BSL functions of the Embedded Power device.
