High-Frequency 6A Sink Synchronous

MOSFET Drivers with Protection Features

The ISL6615 is a high-speed MOSFET driver optimized to

drive upper and lower power N-Channel MOSFETs in a

synchronous rectified buck converter topology. This driver,

combined with an Intersil Digital or Analog multiphase PWM

controller, forms a complete high frequency and high

efficiency voltage regulator.

The ISL6615 drives both upper and lower gates over a range

of 4.5V to 13.2V. This drive-voltage provides the flexibility

necessary to optimize applications involving trade-offs

between gate charge and conduction losses.

The ISL6615 features 6A typical sink current for the low-side

gate driver, enhancing the lower MOSFET gate hold-down

capability during PHASE node rising edge, preventing power

loss caused by the self turn-on of the lower MOSFET due to

the high dV/dt of the switching node.

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. The ISL6615 includes 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 load if

the upper MOSFET(s) is shorted.

The ISL6615 also features an input that recognizes a

high-impedance state, working together with Intersil

multiphase PWM controllers to prevent negative transients

on the controlled output voltage when operation is

suspended. This feature eliminates the need for the Schottky

diode that may be utilized in a power system to protect the

load from negative output voltage damage.
