High-Frequency 6A Sink Synchronous MOSFET

Drivers with Protection Features

ISL6615A

Features

• Dual MOSFET Drives for Synchronous Rectified

Bridge

The ISL6615A 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.

• Advanced Adaptive Zero Shoot-Through Protection

- Body Diode Detection

- LGATE Detection

- Auto-zero of r

DS(ON)

Conduction Offset Effect

The ISL6615A 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

• Supports High Switching Frequency (up to 1MHz)

- 6A LGATE Sinking Current Capability

The ISL6615A 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.

- Fast Rise/Fall Times and Low Propagation Delays

• Support 5V PWM Input Logic

• Tri-State PWM Input for Safe Output Stage Shutdown

• Tri-State PWM Input Hysteresis for Applications with

Power Sequencing Requirement

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 ISL6615A 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.

• Pre-POR Overvoltage Protection

• VCC Undervoltage Protection

• Expandable Bottom Copper PAD for Better Heat

Spreading

• Dual Flat No-Lead (DFN) Package

- Near Chip-Scale Package Footprint; Improves PCB

Efficiency and Thinner in Profile

The ISL6615A 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.

• Pb-free (RoHS compliant)

Applications*(see page 10)

• 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
