ISL6612ACRZ

Gate Driver Overview

The ISL6612ACRZ is a half-bridge gate driver designed for synchronous rectified buck converter topologies. It drives upper and lower N-channel MOSFETs with independent output voltage control, supporting high-frequency operation. Key electrical parameters include a supply voltage range of 10.8V to 13.2V, peak output currents of 1.25A and 2A, and propagation delays of 26ns (rise) and 18ns (fall). The device operates within a junction temperature range of 0°C to 125°C and features adaptive zero shoot-through protection.

Gate Driver Feature Summary

• Integrates advanced adaptive zero shoot-through protection to prevent simultaneous conduction of upper and lower MOSFETs while minimizing dead time.
• Provides independent drive voltage control, allowing the lower gate to be driven over a range from 5V to 12V for optimization of gate charge and conduction losses.
• Includes pre-power-on reset (Pre-POR) overvoltage protection that limits output voltage by connecting the phase node to the low-side gate during initial startup.
• Features a three-state PWM input that prevents negative transients on the output voltage when the output is shut down.

Gate Driver Applications

• Core voltage regulators for Intel and AMD microprocessors
• High current DC/DC converters
• High frequency and high efficiency VRM and VRD applications

Gate Driver Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to availability of counterfeits. Confirm package integrity and marking consistency against official datasheets. Check for moisture sensitivity level compliance if storage conditions are uncertain. Validate lot codes and traceability documentation prior to integration into production systems.

Gate Driver Selection Notes

Select this driver for synchronous buck applications requiring independent high-side and low-side gate voltage adjustment. Ensure compatibility with multi-phase PWM controllers such as HIP63xx or ISL65xx series. Verify that the required switching frequency aligns with the specified rise and fall times. Consider thermal management requirements given the operating temperature range and power dissipation characteristics.
