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

Features

• Dual MOSFET Drives for Synchronous Rectified Bridge

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.

• Advanced Adaptive Zero Shoot-Through Protection

- Body Diode Detection

- LGATE Detection

- Auto-zero of r

DS(ON)

Conduction Offset Effect

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.

• Adjustable Gate Voltage for Optimal Efficiency

• 36V Internal Bootstrap Schottky Diode

• Bootstrap Capacitor Overcharging Prevention

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.

• Supports High Switching Frequency (up to 1MHz)

- 6A LGATE Sinking Current Capability

- Fast Rise/Fall Times and Low Propagation Delays

• Support 3.3V PWM Input logic

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.

• Tri-State PWM Input for Safe Output Stage Shutdown

• Tri-State PWM Input Hysteresis for Applications with

Power Sequencing Requirement

• Pre-POR Overvoltage Protection

• VCC Undervoltage Protection

• Expandable Bottom Copper PAD for Better Heat

Spreading

• Dual Flat No-Lead (DFN) Package

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.

- Near Chip-Scale Package Footprint; Improves PCB

Efficiency and Thinner in Profile

• Pb-Free (RoHS Compliant)

Applications

• Optimized for POL DC/DC Converters for IBA Systems

• Core Regulators for Intel® and AMD® Microprocessors

• High Current Low-Profile DC/DC Converters

• High Frequency and High Efficiency VRM and VRD

• Synchronous Rectification for Isolated Power Supplies
