TLE92104-232QX
The TLE92104-232QX is a MOTIX™ Multi MOSFET Driver IC with an adaptive multi-stage MOSFET gate control
Infineon’s MOTIX™ multiple MOSFET driver can drive up to 8 external n-channel MOSFETs and provides a unique Adaptive MOSFET Control concept to eliminate end-of-line calibration to MOSFET characteristic spreads and guarantees an optimized balancing between power dissipation and EMC behavior. Outstanding low sleep current, advanced protection and diagnostic makes the device to an optimal solution for automotive applications like seat and power lift gate control and various use cases in body control module (BCM) as centralized door lock or washer pumps. An integrated motor brake function is furthermore increasing the reliability and protection for the system. Last but not least, it can control half-bridges with dual supply.
