Product details
Overview
ISL99380HRZ-TR5935 from Renesas Electronics is an 80A Smart Power Stage (SPS) module with integrated high-accuracy current and temperature monitoring, tri-state PWM input, and comprehensive fault protection including HFET overcurrent, SROCP, OTP, and VCC UVLO. It operates from 3.0V to 16V VIN, supports up to 1.25MHz switching, and targets core VR applications for high-performance microprocessors.
For engineers reviewing the ISL99380HRZ-TR5935 datasheet, ISL99380HRZ-TR5935 pinout, ISL99380HRZ-TR5935 application, or ISL99380HRZ-TR5935 equivalent, key selection criteria include ±3% current sense accuracy across line/load/temperature, 8mV/°C analog temperature output (TOUT), RoHS-compliant 5x6 QFN package, and compatibility with Renesas ISL68/69xxx digital multiphase controllers.
Technical Context
The ISL99380HRZ-TR5935 implements a fully integrated power stage with synchronous buck topology, featuring internal high-side and low-side MOSFETs, driver, and sensing circuitry. Its tri-state PWM interface enables robust communication with Renesas DMP controllers during abnormal conditions such as phase loss or shoot-through events.
Current monitoring uses an integrated resistive sense path with ±3% DC accuracy over –40°C to +125°C, while temperature sensing delivers a calibrated 8mV/°C analog output (TOUT) referenced to GND. Fault reporting includes dedicated FLT pin and EN control for system-level coordination.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | +3.0V to +16V - supports standard server and AI accelerator input rails including +5V, +12V, and intermediate bus voltages. |
| Continuous Current | 80A - rated DC output capability without derating at 25°C ambient in typical PCB layout with 2oz copper. |
| Current Sense Accuracy | ±3% - guaranteed over full line, load, and temperature range (–40°C to +125°C), enabling precise loadline compliance. |
| Temperature Monitor | 8mV/°C TOUT output - linear analog voltage proportional to die temperature, referenced to GND, usable for thermal margining and throttling. |
| Switching Frequency | Up to 1.25MHz - allows compact output filter design with reduced inductor size and improved transient response. |
| PWM Input Compatibility | 3.3V tri-state logic - compatible with Renesas ISL68/69xxx digital multiphase controllers; enables phase disable and fault-safe state retention. |
| Fault Protections | HFET overcurrent, shorted HFET, SROCP, OTP, VCC UVLO - autonomous hardware-level responses without controller intervention. |
Pinout & Package
ISL99380HRZ-TR5935 is housed in a thermally enhanced 5mm × 6mm, 32-pin QFN package with exposed thermal pad (RHZ suffix). The package supports high-density board layouts and efficient heat dissipation via bottom-side thermal vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | High-side power input | Primary input rail connection (3.0–16V); ties directly to bulk capacitor and high-side FET source. |
| PHASE | Switch node | Connects to external inductor; carries high dv/dt switching waveform; requires tight layout to minimize EMI. |
| GND | Power ground | Low-impedance return path for both power and signal grounds; must be connected to thermal pad and plane. |
| PWM | Tri-state gate drive input | 3.3V-compatible digital input controlling high-side FET; high-impedance state enables phase shedding. |
| TOUT | Analog temperature output | 8mV/°C voltage referenced to GND; used for real-time die temperature monitoring without ADC calibration. |
| FLT | Fault reporting output | Open-drain active-low signal indicating any active fault condition (OTP, OCP, UVLO, etc.). |
| EN | Enable control input | Active-high logic input; disables all internal circuitry and places outputs in high-impedance safe state when low. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated current monitor | ±3% DC accuracy eliminates need for external DCR sensing network and thermal compensation components. |
| Smart Reverse Overcurrent Protection (SROCP) | Detects reverse current during light-load or CCM-to-DCM transitions, preventing inductor saturation and MOSFET stress. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart power stage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL99390HRZ-T7A | 90A rating, 1.5MHz max frequency, same 5x6 QFN package, ±2.5% current accuracy, adds VOUT telemetry. | Targeted at next-gen AI accelerators requiring higher current density and tighter voltage regulation. | Select when >80A per phase or sub-1% VOUT accuracy is required; not drop-in due to different current sense gain and FLT timing. |

FAQ
What is the maximum continuous output current rating for the ISL99380HRZ-TR5935?
The ISL99380HRZ-TR5935 is rated for 80A continuous DC output current under standard thermal conditions (25°C ambient, 2oz copper PCB, adequate airflow). Derating applies above 70°C case temperature per the thermal characteristics graph in the official Renesas datasheet. This rating assumes proper layout of the PHASE and GND connections to minimize parasitic inductance and ensure reliable operation of the internal MOSFETs in the ISL99380HRZ-TR5935.
Does the ISL99380HRZ-TR5935 support 3.3V or 5V PWM input logic levels?
The ISL99380HRZ-TR5935 supports 3.3V-compatible tri-state PWM input, as confirmed in the Renesas short-form datasheet and electrical specifications table. It is specifically designed to interface with Renesas ISL68/69xxx digital multiphase controllers. The ISL99380BR5935 variant supports 5V logic, but the ISL99380HRZ-TR5935 does not; using 5V on its PWM pin may damage the ISL99380HRZ-TR5935.
How accurate is the current monitoring function in the ISL99380HRZ-TR5935?
The ISL99380HRZ-TR5935 provides ±3% DC current sense accuracy across full line, load, and temperature ranges (–40°C to +125°C), as specified in the Renesas short-form datasheet. This accuracy is achieved via integrated resistive sensing and on-die calibration, eliminating external DCR networks. The ISL99380HRZ-TR5935 delivers this performance without requiring system-level calibration or thermal compensation circuits.
What fault protection mechanisms are built into the ISL99380HRZ-TR5935?
The ISL99380HRZ-TR5935 integrates five hardware-based fault protections: high-side FET overcurrent, shorted high-side FET detection, Smart Reverse Overcurrent Protection (SROCP), over-temperature protection (OTP), and VCC undervoltage lockout (UVLO). All activate autonomously without controller interaction. Each fault asserts the open-drain FLT pin, and the ISL99380HRZ-TR5935 enters a safe high-impedance state until EN is cycled.
Is the ISL99380HRZ-TR5935 RoHS compliant and what package does it use?
Yes, the ISL99380HRZ-TR5935 is RoHS compliant with Exemption 7a and is packaged in a 5mm × 6mm, 32-pin QFN with exposed thermal pad (RHZ suffix). This thermally enhanced package supports high-density PCB layouts and efficient heat transfer to internal ground planes. The ISL99380HRZ-TR5935's RHZ package is standardized across Renesas' SPS portfolio for consistent thermal and mechanical integration.
