ISL15110IRZ

Overview

The ISL15110IRZ is a dual, high-speed MOSFET driver manufactured by Renesas Electronics. It features two independent drivers capable of delivering a peak output current of 3.5 A. The device operates within an input supply voltage range of 2.7 V to 5.5 V and supports a maximum operating frequency of 70 MHz. Typical propagation delays are 40 ns for both turn-on and turn-off states. Rise and fall times are specified at 6.2 ns and 6.9 ns, respectively. The component is housed in a 16-lead QFN package with dimensions of 4 mm x 4 mm and a height of 0.85 mm. It functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel architecture providing independent control for multiple power switches
• High peak output current capability designed for rapid MOSFET switching
• Integrated bootstrap diode simplifies high-side driver implementation
• Low propagation delay ensures precise timing synchronization

Applications

• Synchronous buck and boost DC-DC converter topologies
• Motor drive gate driving circuits
• High-frequency power supply designs

Procurement Notes

Verify the specific suffix 'IRZ' to confirm the lead-free RoHS-compliant variant and QFN packaging configuration. Ensure the ordering code matches the exact pin count and thermal pad requirements for your PCB layout. Confirm that the manufacturer designation aligns with Renesas Electronics to avoid counterfeit components. Cross-reference the date code against current production status to ensure availability.

Selection Notes

Select this component when dual isolated or non-isolated high-speed switching is required within a low-voltage logic domain. The 3.5 A peak current rating suits medium-power MOSFETs where fast transition times reduce switching losses. Consider the QFN package for applications requiring compact footprints and efficient thermal dissipation through the exposed pad. Evaluate the 70 MHz frequency limit against your specific switching requirements.
