DATASHEET 00V/2A Peak, Low ost, High Frequency Half Bridge Driver FN4022 Rev 5.00 The is a high frequency, 00V Half Bridge N-hannel power MOSFET driver I. The low-side and high-side gate drivers are independently controlled and matched to 8ns. This gives the user maximum flexibility in dead-time selection and driver protocol. Undervoltage protection on both the low-side and high-side supplies force the outputs low. An on-chip diode eliminates the discrete diode required with other driver Is. A new level-shifter topology yields the low-power benefits of pulsed operation with the safety of D operation. Unlike some competitors, the high-side output returns to its correct state after a momentary undervoltage of the high-side supply.
