TLE9850QX
TLE9850QX is designed for unidirectional automotive applications such as HVAC Blower
TLE9850QX is part of the Infineon TLE985x MOTIX™ 32-bit motor control SoC 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 two fully integrated NFET drivers 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 MOTIX™ 32-bit motor control SoC 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.
