ISL6613CBZ-T

DATASHEET ISL6612, ISL6613 Advanced Synchronous Rectified Buck MOSFET Drivers with Protection Features The ISL6612 and ISL6613 are high frequency MOSFET drivers specifically designed to drive upper and lower power N-Channel MOSFETs in a synchronous rectified buck converter topology. These drivers combined with HIP63xx or ISL65xx Multi-Phase Buck PWM controllers and N-Channel MOSFETs form complete core-voltage regulator solutions for advanced microprocessors. The ISL6612 drives the upper gate to 12V, while the lower gate can be independently driven over a range from 5V to 12V. The ISL6613 drives both upper and lower gates over a range of 5V to 12V. This drive-voltage provides the flexibility necessary to optimize applications involving trade-offs between gate charge and conduction losses. An advanced adaptive zero shoot-through protection is integrated to prevent both the upper and lower MOSFETs from conducting simultaneously and to minimize the dead time. These products add an overvoltage protection feature operational before VCC exceeds its turn-on threshold, at which the PHASE node is connected to the gate of the low side MOSFET (LGATE). The output voltage of the converter is then limited by the threshold of the low side MOSFET, which provides some protection to the microprocessor if the upper MOSFET(s) is shorted during startup. The over-temperature protection feature prevents failures resulting from excessive power dissipation by shutting off the outputs when its junction temperature exceeds +150°C (typically). The driver resets once its junction temperature returns to +108°C (typically). These drivers also feature a three-state PWM input which, working together with Intersil’s multi-phase PWM controllers, prevents a negative transient on the output voltage when the output is shut down. This feature eliminates the Schottky diode that is used in some systems for protecting the load from reversed output voltage events.
