Product details
Overview
RAA2213404GNP#HB0 from Renesas Electronics is a 40A Smart Power Stage (SPS) with integrated high-accuracy current and temperature monitoring, designed for multiphase DC/DC VRM/VRD systems. It features ±3% IMON accuracy, 8mV/°C TMON output, 3.3V-compatible tri-state PWM input, 1.5MHz max switching frequency, and comprehensive fault protection including UVLO, overtemperature, and shorted HFET detection.
For engineers reviewing the RAA2213404GNP#HB0 datasheet, RAA2213404GNP#HB0 pinout, RAA2213404GNP#HB0 application, or RAA2213404GNP#HB0 equivalent, this device serves as a drop-in SPS replacement for ISL68xxx/69xxx-based high-density power delivery in server CPU/GPU core rails, where DCR-sensing elimination and real-time thermal/current telemetry are critical.
Technical Context
The RAA2213404GNP#HB0 implements downslope current sensing with an internal REF IN reference input to enable precise IMON feedback to digital multiphase controllers. Its tri-state PWM interface supports robust start-up and fault-handling handshake via FAULT# and TMON signals.
Thermal monitoring is provided through an analog 8mV/°C voltage output with OT flag assertion, while fault protection includes VCC UVLO, overcurrent detection on both high- and low-side FETs, and shoot-through prevention logic - all implemented within the monolithic PQFN die.

FAQ
What is the maximum continuous current rating of the RAA2213404GNP#HB0?
The RAA2213404GNP#HB0 supports a continuous current rating of 40A under typical thermal conditions with proper PCB layout and heatsinking. This rating is validated across its full input voltage range (3.0V to 16V) and up to 1.5MHz switching frequency. Derating applies above 85°C ambient or with insufficient copper area; full thermal guidelines are specified in the RAA2213404GNP#HB0 datasheet Section 5.2.
Does the RAA2213404GNP#HB0 require external current sense resistors?
No, the RAA2213404GNP#HB0 integrates downslope current sensing and provides an analog IMON output with ±3% accuracy, eliminating the need for external DCR sensing networks or shunt resistors. The REF IN pin allows system-level calibration of the IMON gain, making the RAA2213404GNP#HB0 suitable for precision multiphase current balancing without added BOM cost or layout area.
How does the RAA2213404GNP#HB0 communicate temperature data to the controller?
The RAA2213404GNP#HB0 provides temperature telemetry via the TMON pin, which outputs a linear 8mV/°C analog voltage referenced to GND. An overtemperature (OT) flag is asserted when die temperature exceeds the threshold. This dual-mode output enables both fine-grained thermal margining and hard fault shutdown - a capability confirmed in the RAA2213404GNP#HB0 Short-Form Datasheet Rev. 1.01, Section 2.3.
Is the RAA2213404GNP#HB0 pin-compatible with other Renesas Smart Power Stages?
The RAA2213404GNP#HB0 uses a 25-lead 4×5 mm PQFN package with a defined pinout optimized for ISL68xxx/69xxx controller compatibility. While it shares functional similarity with RAA221330 and RAA221350, pin assignments differ - particularly for IMON, REF IN, and TMON. Therefore, the RAA2213404GNP#HB0 is not pin-compatible with other members of the RAA2213xx family without PCB revision.
What fault protection mechanisms are integrated into the RAA2213404GNP#HB0?
The RAA2213404GNP#HB0 integrates UVLO on VCC, overtemperature detection with OT flag, cycle-by-cycle overcurrent protection, and shorted HFET detection. Faults are reported via the open-drain FAULT# pin, which can disable the controller during startup or abnormal conditions. These protections are implemented entirely within the RAA2213404GNP#HB0 die and require no external components, as verified in the RAA221340 Short-Form Datasheet Section 3.1.
