ISL6614IBZR5238

Gate Driver Overview

The ISL6614IBZR5238 is a dual synchronous buck gate driver manufactured by Intersil, housed in a 14-SOIC package. It provides non-inverting half-bridge drive capabilities with peak output currents of 1.25A sourcing and 2A sinking. The device supports high switching frequencies up to 1MHz and features advanced adaptive zero shoot-through protection. Operating parameters include a supply voltage range of 10.8V to 13.2V, propagation delay of 10ns maximum, rise time of 26ns, and fall time of 18ns.

Gate Driver Feature Summary

• Advanced adaptive zero shoot-through protection utilizing body diode detection and auto-zero conduction offset compensation
• Supports high switching frequencies up to 1MHz with dedicated 3A sinking current capability
• Includes internal bootstrap Schottky diode and bootstrap capacitor overcharging prevention mechanisms
• Features three-state PWM input with hysteresis for precise output stage shutdown control

Gate Driver Applications

• Synchronous rectified bridge drives
• High-frequency DC-DC converter topologies
• Power management integrated circuits requiring adaptive dead-time control

Gate Driver Procurement Notes

Verify the specific suffix IBZR5238 against official Renesas or Intersil documentation to confirm pinout and electrical characteristics match the 14-SOIC dual sync buck configuration. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the datasheet. Cross-reference part numbers carefully as suffixes often indicate packaging variations or manufacturing site changes that may affect physical dimensions or handling requirements without altering core functionality.

Gate Driver Selection Notes

Select this component when designing synchronous buck converters requiring adaptive shoot-through protection and high-speed switching performance. The dual channel architecture suits applications needing independent control of high-side and low-side MOSFETs. Consider the 14-SOIC package for surface-mount assembly constraints. Evaluate the 1.25A source and 2A sink currents against the target MOSFET gate charge requirements at the intended operating frequency to ensure adequate drive strength.

Gate Driver Part Context

This device belongs to the ISL6614 family of gate drivers designed for power management applications. It integrates specialized protection features to enhance efficiency in synchronous rectification schemes. The manufacturer transitioned from Intersil to Renesas Electronics, maintaining the same functional specifications under the updated corporate branding structure.

Gate Driver Replacement Considerations

Direct substitutes include other models within the ISL6614 series such as ISL6614CRZ or ISL6614ACBZR, provided the package type and pinout are compatible. Verify that alternative parts maintain the same adaptive zero shoot-through protection and current drive capabilities.
