ISL99227IRZ-T7A

Overview

The ISL99227IRZ-T7A is a Smart Power Stage (SPS) module from the ISL99227 series, manufactured by Renesas Electronics. It integrates high-accuracy power stage components into a single PQFN-32 package for surface mount installation. The device supports an input voltage range of 4.5 V to 18 V and delivers up to 60 A output current with a maximum regulated output voltage of 3.3 V. Operating within a temperature range of -40 °C to +85 °C, it features a quiescent current of 15 mA and handles a power dissipation of 12.5 W. This component is designed for high-density point-of-load applications requiring high efficiency.

Procurement Notes

Verify the specific ordering suffix T7A to confirm reel packaging specifications. Confirm RoHS compliance status through official documentation prior to integration. Check for end-of-life notifications as some sources indicate potential obsolescence for this part number. Ensure moisture sensitivity level requirements are met during storage and handling procedures.

Selection Notes

Select this component when designing systems requiring integrated high-current power stages up to 60 A. The fixed 3.3 V output limits flexibility compared to adjustable variants; verify if this voltage aligns with target load requirements. Consider the PQFN-32 package thermal performance for the intended application environment. Evaluate compatibility with existing controller ICs if not using an integrated solution.

Part Context

The ISL99227 belongs to the ISL99227 series of professional power management ICs from Renesas. It represents a specialized PMIC category distinct from general-purpose regulators or battery management controllers found in other product lines. The device leverages Intersil heritage technology for high-performance voltage regulation in computing infrastructure.
