Description
The OPTIREG™ PMIC TLF11251LD is a 2.5 A half bridge with integrated driver and level shifter. It also contains
a high side P-channel MOSFET and a low side N-channel MOSFET in a single package. The integrated level
shifting stage allows for conversion of the input logic signals to the supply voltage level of the gate drivers. The
input signal levels are CMOS compatible. The level shifter and the gate driver provide a dead time generation
to simplify the interface with the embedded core voltage regulator of the AURIX™ TC3xx microcontroller. The
low propagation delay allows for use in closed loop control applications with limited requirements for timing.
The output stage allows for a high switching frequency. The TLF11251LD integrates protection features against
overcurrent at the high side MOSFET and at the low side MOSFET as well as against overtemperature events.
Internal power-on reset releases the digital logic and ensures its operation for the supply voltage within the
specified range.
