Renesas Electronics Corporation Gate Drivers ISL6614AIBZ-T

The ISL6614AIBZ-T is a dual advanced synchronous rectified buck MOSFET driver designed to drive two N-Channel MOSFETs in synchronous rectified buck converter applications. It operates with a gate drive voltage range of 5V to 12V, allowing for optimization between gate charge and conduction losses. The driver features advanced adaptive zero shoot-through protection to prevent simultaneous conduction of the upper and lower MOSFETs, minimizing dead time. This product includes a pre-POR overvoltage protection feature that activates before the VCC exceeds its turn-on threshold, providing additional safety for connected microprocessors. The ISL6614AIBZ-T supports high switching frequencies of up to 1MHz and has a sinking current capability of 3A, ensuring fast rise and fall times with low propagation delays. It also incorporates a three-state PWM input for output stage shutdown, which helps eliminate negative transients during shutdown. The device is available in a 14-lead SOIC package and is compliant with RoHS standards. It is suitable for applications such as core voltage regulators for Intel and AMD microprocessors, high current DC/DC converters, and high-frequency, high-efficiency voltage regulator modules.
