MIC4606

85V Full-Bridge MOSFET Drivers with Adaptive Dead Time and

Shoot-Through Protection

Features

General Description

• 5.5V to 16V Gate Drive Supply Voltage Range

• Advanced Adaptive Dead Time

• Intelligent Shoot-Through Protection

• MIC4606-1: Four Independent TTL Inputs

• MIC4606-2: Two PWM Inputs

• Enable Input for On/Off Control

• On-Chip Bootstrap Diodes

• Fast 35 ns Propagation Times

• Drives 1000 pF Load with 20 ns Rise and

Fall Times

The MIC4606 is an 85V full-bridge MOSFET driver that

features adaptive dead time and shoot-through protec-

tion. The adaptive dead-time circuitry actively monitors

both sides of the full bridge to minimize the time

between high-side and low-side MOSFET transitions,

thus maximizing power efficiency. Anti-shoot-through

circuitry prevents erroneous inputs and noise from

turning both MOSFETs of each side of the bridge on at

the same time.

The MIC4606 also offers a wide 5.5V to 16V operating

supply range to maximize system efficiency. The low

5.5V operating voltage allows longer run times in

battery-powered applications. Additionally, the MIC4606

device’s adjustable gate drive sets the gate drive voltage

to V_DDfor optimal MOSFET R_DS(ON), which minimizes

• Low Power Consumption: 235 µA Total Quiescent

Current

• Separate High-Side and Low-Side Undervoltage

Protection

• -40°C to +125°C Junction Temperature Range

power loss due to the MOSFET’s R_DS(ON)

Applications

The MIC4606-1 features four independent inputs while

the MIC4606-2 utilizes two PWM inputs, one for each

side of the H-bridge. The MIC4606-1 and MIC4606-2

are available in a 16-pin 4 mm x 4 mm QFN package,

and a 16-pin 4 mm x 5 mm TSSOP package with an

operating temperature range of -40°C to +125°C.

• Full-Bridge Motor Drives

• Power Inverters

• High-Voltage Step-Down Regulators

• Distributed Power Systems

• Stepper Motors
