Product details
Overview
RAA221340RGNP#HB0 from Renesas Electronics is a 40A Smart Power Stage (SPS) with integrated high-accuracy current and temperature monitors, 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, overcurrent, shorted HFET, and over-temperature detection.
For engineers reviewing the RAA221340RGNP#HB0 datasheet, RAA221340RGNP#HB0 pinout, RAA221340RGNP#HB0 application, or RAA221340RGNP#HB0 equivalent, this device serves as a drop-in SPS replacement for ISL68xxx/69xxx controller-based high-density POL designs requiring precise current sensing, thermal monitoring, and robust fault reporting without external DCR networks.
Technical Context
The RAA221340RGNP#HB0 integrates a high-side and low-side MOSFET pair with driver, downslope current sensing, and analog monitor outputs (IMON, TMON, FAULT#). Its tri-state PWM interface enables seamless interoperability with Renesas digital multiphase controllers during startup, shutdown, and fault conditions.
It implements shoot-through protection, VCC undervoltage lockout at 4.5V, and thermal shutdown at 150°C with OT flag assertion. The IMON output provides ratiometric current feedback referenced to REFIN, enabling accurate phase-current balancing in multi-phase systems.
Key Specifications

| Package | 25-lead 4×5mm PQFN - thermally enhanced footprint with exposed thermal pad for efficient heat dissipation in dense layouts |
Pinout & Package
RAA221340RGNP#HB0 uses a 25-lead, 4mm × 5mm, 0.5mm pitch PQFN package with an exposed thermal pad (EP) on the bottom side for optimal thermal performance. Pin numbering follows standard JEDEC outline MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | High-side MOSFET drain input | Primary power input node connected to bulk input capacitor; handles full phase current |
| SW | Switch node | Connection point between high- and low-side FETs; drives output inductor and requires low-inductance layout |
| PHASE | PWM input | 3.3V-compatible tri-state logic input controlling high-side gate drive timing and dead-time management |
| BOOT | Bootstrap supply | Provides floating gate drive voltage for high-side MOSFET; requires external bootstrap capacitor |
| EN | Enable input | Active-high logic input enabling internal gate drivers; used for sequencing and fault recovery |
| IMON | Analog current monitor output | Ratiometric analog voltage proportional to sensed current; referenced to REFIN for accuracy |
| REFIN | Reference input | External reference voltage input (typically 1.0V) for IMON scaling and calibration |
| TMON | Analog temperature monitor output | Linear 8mV/°C output referenced to GND; used for die temperature readback and thermal throttling |
| FAULT# | Open-drain fault indicator | Active-low signal asserting on UVLO, overcurrent, shorted HFET, or over-temperature events |
| GND | Power and signal ground | Common return path for power, logic, and analog monitor circuits; must be low-impedance |
| VCC / PVCC | Internal LDO supply inputs | VCC powers logic and monitors; PVCC supplies gate drivers - both require local decoupling |

FAQ
What is the maximum continuous current rating of the RAA221340RGNP#HB0?
The RAA221340RGNP#HB0 is rated for 40A continuous DC output current under typical board-level thermal conditions (4-layer PCB, 2oz copper, 200LFM airflow). Derating applies above 70°C ambient or with reduced copper area. This rating is validated per JEDEC JESD51-2 and confirmed in the R16DO0001EU0101 datasheet revision.
Does the RAA221340RGNP#HB0 require an external current sense resistor?
No, the RAA221340RGNP#HB0 does not require an external current sense resistor. It implements integrated downslope current sensing using MOSFET RDS(on) and internal precision amplifiers, delivering ±3% accurate IMON output referenced to the REFIN pin. This eliminates DCR networks and associated thermal compensation components.
How does the RAA221340RGNP#HB0 communicate temperature data to the controller?
The RAA221340RGNP#HB0 communicates die temperature via the analog TMON pin, which outputs a linear 8mV/°C voltage referenced to GND. An over-temperature (OT) flag is asserted when junction temperature exceeds 150°C. No I²C or digital interface is used - the controller reads TMON with an ADC and monitors FAULT# for OT events.
Is the RAA221340RGNP#HB0 pin-compatible with other Renesas SPS devices like the RAA221330?
No, the RAA221340RGNP#HB0 is not pin-compatible with the RAA221330. While both share the same 4×5mm PQFN-25 package outline, pin functions differ - notably PHASE, BOOT, and FAULT# assignments - and the RAA221330 lacks REFIN and TMON outputs. PCB layout must be verified against each device's specific pinout table.
What fault protection mechanisms are built into the RAA221340RGNP#HB0?
The RAA221340RGNP#HB0 integrates five fault protections: VCC undervoltage lockout (UVLO), shorted high-side FET detection, cycle-by-cycle overcurrent limiting, over-temperature shutdown (150°C), and thermal OT flag assertion. All faults trigger the open-drain FAULT# pin and can disable the controller via EN pin coordination, as documented in the R16DO0001EU0101 datasheet.
