ISL6237IRZ

Special Purpose Regulators Overview

The ISL6237IRZ is a hot-swap voltage controller designed for notebook power systems, supporting the Intel IMVP-6 specification. It features four output channels and operates within an input voltage range of 5.5V to 25V. The device is housed in a 32-pin QFN package measuring 5x5 mm with an exposed pad. It supports a wide operating temperature range from -40°C to +100°C and carries a Moisture Sensitivity Level (MSL) rating of 3.

Special Purpose Regulators Feature Summary

• Implements Intel IMVP-6 protocol for synchronized multi-phase control
• Integrates hot-swap protection circuitry for safe power insertion
• Supports four independent output channels for complex power rails

Special Purpose Regulators Applications

• Notebook computer power management systems
• Intel IMVP-6 compliant motherboard designs
• Multi-rail DC-DC conversion architectures

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors due to end-of-life status. Confirm RoHS compliance documentation matches current regulatory requirements. Check for moisture sensitivity handling precautions during storage and assembly. Validate package marking against official datasheet specifications to prevent counterfeit substitution.

Special Purpose Regulators Selection Notes

Select this controller for legacy notebook platforms requiring IMVP-6 compatibility. Ensure input supply voltage remains within the 5.5V to 25V operational window. Verify thermal design accommodates the 5x5 QFN package constraints. Consider obsolescence implications for long-term production support when integrating into new hardware designs.
