Overview
ISL99380FRZ-TR5935 from Renesas Electronics is an 80A Smart Power Stage (SPS) module with integrated high-accuracy current and temperature monitors, designed for use with ISL68/69xxx digital multiphase controllers. It supports 3.3V tri-state PWM input, delivers ±3% continuous current sense accuracy, operates up to 1.25MHz, and targets core/GPU VR applications requiring precision loadline regulation.
For engineers reviewing the ISL99380FRZ-TR5935 datasheet, ISL99380FRZ-TR5935 pinout, ISL99380FRZ-TR5935 application, or ISL99380FRZ-TR5935 equivalent, key selection criteria include tri-state PWM compatibility, integrated current/temperature monitoring, fault protection coverage (SROCP, OTP, UVLO), and 5×6 QFN thermal performance in high-density POL designs.
Technical Context
The ISL99380FRZ-TR5935 implements a fully integrated power stage with high-side and low-side MOSFETs, driver, and sensing circuitry in a single 5×6 mm QFN package. Its tri-state PWM interface enables seamless coordination with Renesas digital controllers during phase shedding or fault conditions.
It provides real-time analog current monitoring (±3% accuracy across line/load/temp) and linear temperature output (8mV/°C on TOUT pin), eliminating external DCR sensing networks and thermal compensation components required in discrete solutions.
Key Specifications

Pinout & Package
Package: 32-pin, 5mm × 6mm, 0.5mm pitch QFN with exposed thermal pad (RoHS compliant, Exemption 7a).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | High-side FET drain supply | Primary input power connection; must be decoupled near pin with low-ESR ceramic capacitors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar smart power stage applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL99390FRZ-T7A | 90A rating, 5×6 QFN, same tri-state PWM interface but 5V-compatible; ±2.5% current sense accuracy. | Targeted for higher-current CPU VRs where 90A headroom is required; not drop-in due to PWM voltage mismatch. | Select ISL99390FRZ-T7A only if controller outputs 5V PWM and system requires >80A sustained current. |
| MP87653GL-10-Z | 80A rating, 6×6 QFN, 3.3V PWM compatible, ±3.5% current sense accuracy, no integrated temperature monitor. | Suitable for cost-sensitive industrial VRs where thermal telemetry is handled externally; larger footprint limits density. | Choose MP87653GL-10-Z when board area is less constrained and separate temperature sensing is already implemented. |
Compared with ISL99380FRZ-TR5935, ISL99390FRZ-T7A offers higher current capacity but requires 5V PWM signaling, while MP87653GL-10-Z lacks integrated temperature monitoring and occupies more PCB area-making ISL99380FRZ-TR5935 optimal for space-constrained, thermally aware 3.3V-controller-based GPU/AI VR designs.

FAQ
What is the maximum continuous output current supported by the ISL99380FRZ-TR5935?
The ISL99380FRZ-TR5935 is rated for 80A continuous DC output current under typical thermal conditions (25°C ambient, 2oz copper, 4-layer PCB, 200LFM airflow). Derating applies above 70°C case temperature per the thermal characteristics graph in the official Renesas datasheet. The device maintains this rating without external current-sense resistors thanks to its integrated ±3% accurate monitor.
Does the ISL99380FRZ-TR5935 require external DCR sensing components?
No, the ISL99380FRZ-TR5935 does not require external DCR sensing components. It integrates high-accuracy current sensing circuitry with ±3% accuracy across line, load, and temperature, eliminating the need for discrete sense resistors, compensation networks, or thermal sensors typically used in DCR-based solutions. This integration simplifies layout and improves system reliability.
What fault protection features are built into the ISL99380FRZ-TR5935?
The ISL99380FRZ-TR5935 includes HFET overcurrent protection, Smart Reverse Overcurrent Protection (SROCP), over-temperature protection (OTP), and VCC undervoltage lockout (UVLO). These protections operate autonomously and assert the open-drain FLT signal to notify the controller. No external circuitry is needed to implement these safety functions, enhancing system robustness in mission-critical VR applications.
Can the ISL99380FRZ-TR5935 be used with non-Renesas digital PWM controllers?
The ISL99380FRZ-TR5935 is optimized for Renesas ISL68/69xxx controllers and phase doublers, particularly due to its tri-state PWM interface timing and PHASE feedback protocol. While basic switching may function with other 3.3V PWM sources, full feature support-including current reconstruction, AVP, and fault reporting-requires Renesas controller compatibility as specified in the ISL99380FRZ-TR5935 datasheet.
What is the purpose of the TOUT pin on the ISL99380FRZ-TR5935?
The TOUT pin on the ISL99380FRZ-TR5935 provides a linear analog voltage output of 8mV/°C, directly proportional to the internal MOSFET die temperature. When FLT is high (no fault), TOUT delivers real-time thermal telemetry to the controller's ADC, enabling closed-loop thermal management without external sensors. During fault conditions, TOUT is disabled and FLT goes low.
