Product validation Qualified for automotive applications. Product validation according to AEC-Q100/101. Description The TLF11251 is an integrated gate driver and half-bridge with 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 TM 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 TLF11251 integrates protection features against overcurrent at high-side MOSFETs and low-side MOSFETs and against overtemperature events. Internal power-on reset releases the digital logic and ensures its operation for supply voltage within the specified range.
