TLE9851QXW optimizes single-phase DC pumps and fans such as HVAC blower
TLE9851QXW is part of the TLE985x Infineon Embedded Power IC product family. The single chip single-phase motor driver integrates the industry standard Arm® Cortex®-M0 core with an NFET driver. This System-on-Chip solution includes a fully integrated NFET driver optimized to drive a single-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. 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.
Produced on Infineon's first-in-industry automotive qualified 130 nm Smart Power technology, the Infineon Embedded Power System-on-Chip solution offers an unmatched level of integration as well as system cost to performance optimization for the target application segments.
The TLE985x product family is offered in a leadless VQFN-48 package to save board space.

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.
Micro Inspector Pro is a graphical visualization tool within Infineon Toolbox to interact with Infineon embedded systems based on Arm® Cortex®-M cores.
Micro Inspector Pro in unregistered mode (without entering a license key) allows the complete usage of existing dashboards. With the registered version, saving a modified or newly created dashboard is possible.
The license key to register can be requested via Infineon support channel: https://www.infineon.com/tac
IHR and Vector are proven partners for drivers and driver configuration tools compatible with Infineon´s range of Embedded Power ICs, and support LIN specifications 1.3, 2.0 and 2.1. The offered solution provides a wide range of options for designers, with reliable testing specifications, intuitive operation, and diagnostic services.
QM-parts in Functional Safety Applications (ASIL)
Infineon´s Embedded Power ICs are developed as QM-parts, but nonetheless can be and are already used in a variety of motor control application that require Functional Safety (ISO26262) up to ASIL-B such as but not limited to Window Lift (ASIL-A), Sunroof (ASIL-A), Auxiliary pumps (ASIL-B) or Engine Cooling Fan (ASIL-B).
Infineon offers the following design-in support for its Embedded Power ICs:
- FIT data information (ISO26262)
- Function/Blocks vs. Area Breakdown
