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.

Features

• Pin-to-pin Compatible with HIP6602 SOIC family for Better

Performance and Extra Protection Features

• Quad N-Channel MOSFET Drives for Two Synchronous

Rectified Bridges

• Advanced Adaptive Zero Shoot-Through Protection

- Body Diode Detection

- Auto-zero of r

Conduction Offset Effect

DS(ON)

• Adjustable Gate Voltage (5V to 12V) for Optimal Efficiency

• Internal Bootstrap Schottky Diode

• Bootstrap Capacitor Overcharging Prevention

• Supports High Switching Frequency (up to 1MHz)

- 3A Sinking Current Capability

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.

- Fast Rise/Fall Times and Low Propagation Delays

• Three-State PWM Input for Output Stage Shutdown

• Three-State PWM Input Hysteresis for Applications With

Power Sequencing Requirement

• Pre-POR Overvoltage +Protection

• VCC Undervoltage Protection

• Over Temperature Protection (OTP) with 42°C Hysteresis

• Expandable Bottom Copper Pad for Enhanced Heat

Sinking

• QFN Package:

- Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat

No Leads - Package Outline

- Near Chip Scale Package footprint, which improves

PCB efficiency and has a thinner profile

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).

• Pb-Free Plus Anneal Available (RoHS Compliant)

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.

Applications

• Core Regulators for Intel® and AMD® Microprocessors

• High Current DC-DC Converters

• High Frequency and High Efficiency VRM and VRD

Processing Moisture Sensitive Surface Mount Devices

(SMDs)”

Layout Guidelines, and Feedback Compensation Design

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
