ISL6594A and ISL6594B are high -frequency MOSFETs designed to drive up and down power to synchronize the N -channel MOSFET converter topology in the rectification buck. These drivers form a complete core voltage advanced microprocessor regulator solution with the ISL6592 digital multi -phase lower -voltage pulse controller N channel MOSFET. ISL6594A drives the upper grid to 12V , and the lower grille can independently drive 12V.ISL6594B to the upper and lower grille 5V to 12V within the range of 5V to 5V. This driving voltage provides the flexibility required for optimizing applications, including the balance between door charge and conduction loss. Adaptive zero penetration protection is integrated until the up and down MOSFET transmission is reduced at the same time as much as possible. These products increase the operation overvoltage protection function connected to the gate MOSFET (LGATE) at the low -voltage side before VCC exceeds its opening threshold. The output voltage of the converter is then limited by the low -side MOSFET threshold to provide some protection for microprocessors. If the initial startup period, MOSFET is short -circuit. These drivers also have a three -state PWM input that work with the multi -phase PWM controller of the Intersil, and the output is closed. This characteristic eliminates the diode in some Schartky system to protect the load from reverse output voltage events.
