Product Overview
TLF11251LDXUMA1 is an Infineon automotive integrated half-bridge intended as a high-current companion stage for OPTIREG PMIC and AURIX microcontroller core-supply architectures. It combines a P-channel high-side MOSFET, N-channel low-side MOSFET, gate drivers and level shifting in one 2.5 A output stage.
Integrated dead-time control, current sensing/limiting and over-temperature protection reduce the external circuitry needed around the half bridge.

Automotive Integration Considerations
The half bridge is intended to work with the surrounding PMIC and processor-core regulation concept. Current limit and thermal protection are safeguards, not substitutes for inductor, load-transient and PCB thermal design.
