High-Frequency 6A Sink Synchronous MOSFET Drivers with Protection Features

The ISL6615A is a high-speed MOSFET driver optimized to

Features

drive upper and lower power N-Channel MOSFETs in a

• 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

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.

- Auto-zero of r

DS(ON)

Conduction Offset Effect

• Adjustable Gate Voltage for Optimal Efficiency

• 36V Internal Bootstrap Schottky Diode

• Bootstrap Capacitor Overcharging Prevention

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.

• Supports High Switching Frequency (up to 1MHz)

- 6A LGATE Sinking Current Capability

- Fast Rise/Fall Times and Low Propagation Delays

• Support 5V 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 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.

• 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

- 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

• 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

Processing Moisture Sensitive Surface Mount Devices
