Infineon Technologies TLE985x H-Bridge MOSFET Driver ICs
Infineon Technologies TLE985x H-Bridge MOSFET Driver ICs are single-chip 2-phase motor drivers that integrate an Arm® Cortex® M0 core with an NFET driver. These ICs feature four fully integrated NFET drivers, a charge pump enabling low voltage operation, and programmable current along with current slope control. The four fully integrated NFET drivers optimized to drive a 2-phase motor via four external power NFETs. The TLE985x ICs come in a leadless VQFN-48 package to save board space. These ICs supply external loads with the help of an on-chip linear voltage regulator.
The TLE985x IC's peripheral set includes a successive approximation ADC synchronized with the capture and compare unit for PWM control, a current sensor, and 16-bit timers. These ICs also include an integrated LIN transceiver to enable communication to the device along with a number of general purpose I/Os. Typical applications include window lift, sunroof, electrical fan, electrical pumps, and LIN addressed motor control.
