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 4.5 V to 16 V. 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 270 ns of drive delay. For applications that require longer times, precision comparator input thresholds allow simple RC circuits to generate longer time delays.
The ISL89367 available now in a 3 mm x 5 mm, 16-pin TDFN package and is priced at $4.00 each in 1,000-unit quantities.
