To-kanals MOSFET driver kan levere 6A

Intersil introducerer hvad firmaet betegner som verdens første high-speed, to-kanals 6A MOSFET driver

Intersil Corp. introduces the ISL89367, the industry's first dual channel 6A MOSFET driver capable of driving two outputs each with 6A of peak drive current. This unique part provides designers with an integrated solution for high speed driving of large, high current MOSFETs. The device is ideally suited for applications such as switching power supplies, motor drivers and Class-D amplifiers.

The driver's fast rise and fall times assure lower power losses and significant improvements in efficiency over competitive devices with drive voltages ranging from 4.5V to 16V. Programmable switching delay times prevent shoot-through current between MOSFETs, and allow optimization for maximum efficiency and reduced electromagnetic interference.

For isolated applications, the ISL89367's precision logic thresholds simplify the design of synchronous rectification on the secondary side of the transformer. Internal timers can be programmed to provide up to 270ns of drive delay. For applications that require longer times, precision comparator input thresholds allow simple RC circuits to generate longer time delays.

Features and specifications
• Industry's fastest 6A MOSFET driver
o 25ns propagation delay
o 20ns rise and fall times
• Wide 4.5V to 16V operation
• Accurate programmable delay times
• Unique precision logic input thresholds (+/-3.75%)
• Typical ON-resistance of only 1 Ohm
• 'Miller plateau' drive current of 5A

The ISL89367 available now in a 3mm x 5mm, 16-pin TDFN package and is priced at $4.00 each in 1,000-unit quantities.
