ISL6614
Dual Advanced Synchronous Rectified Buck MOSFET Drivers with Protection
Features
The ISL6614 integrates two ISL6613 MOSFET drivers and is
specifically designed to drive two independent power
channels in a Multi-Phase interleaved 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 ISL6614 drives both the upper and lower gates
simultaneously over a range from 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).
The ISL6614 also features 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.
