Product details
Overview
ISL99380BFRZ-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 and ISL6617A phase doublers in high-density VR applications. It supports 3.0V–16V VIN, delivers ±3% continuous current sense accuracy, and features 5V-compatible tri-state PWM input and 8mV/°C analog temperature output (TOUT).
For engineers reviewing the ISL99380BFRZ-TR5935 datasheet, ISL99380BFRZ-TR5935 pinout, ISL99380BFRZ-TR5935 application, or ISL99380BFRZ-TR5935 equivalent, key selection criteria include tri-state PWM compatibility, integrated fault protection (SROCP, OTP, UVLO), current monitor accuracy over line/load/temperature, and thermal performance in 5x6 QFN packaging.
Technical Context
The ISL99380BFRZ-TR5935 implements a fully integrated power stage with high-side and low-side MOSFETs, driver, current sense amplifier, and temperature sensor in a single thermally enhanced 5x6 mm QFN package. Its tri-state PWM interface enables seamless synchronization with Renesas digital controllers during abnormal conditions such as phase loss or shoot-through events.
It eliminates external DCR sensing networks and thermal compensation components by delivering direct analog current and temperature outputs (CS#n, TOUT), supporting up to 1.25MHz switching frequency while maintaining ±3% current monitoring accuracy across line, load, and temperature ranges.

FAQ
What is the PWM input voltage compatibility for ISL99380BFRZ-TR5935?
The ISL99380BFRZ-TR5935 features a 5V-compatible tri-state PWM input, designed to interface directly with Renesas ISL6617A phase doublers and ISL69xxx digital multiphase controllers. This differs from the 3.3V-compatible ISL99380R5935 variant. The 5V logic threshold ensures robust noise immunity and timing margin in high-speed server VR environments where ISL99380BFRZ-TR5935 is deployed.
Does ISL99380BFRZ-TR5935 require external current sense resistors or DCR networks?
No, the ISL99380BFRZ-TR5935 integrates high-accuracy current sensing and eliminates the need for external DCR networks or sense resistors. Its ±3% current monitor output (CS#n) is ratiometric to load current and calibrated across line, load, and temperature. This integration reduces component count, PCB area, and thermal compensation complexity - a key advantage of ISL99380BFRZ-TR5935 in high-density VR designs.
How does the Smart Reverse Overcurrent Protection (SROCP) function in ISL99380BFRZ-TR5935?
SROCP in ISL99380BFRZ-TR5935 detects reverse current flow during light-load or transient conditions - such as phase shedding or sudden load release - and autonomously disables the low-side FET to prevent energy backflow. This feature improves efficiency and reliability in multi-phase systems and is implemented entirely within ISL99380BFRZ-TR5935 without controller dependency.
What thermal performance can be expected from ISL99380BFRZ-TR5935 in a typical 6-layer PCB layout?
In a standard 6-layer PCB with 2oz copper, internal thermal planes, and proper thermal via array under the exposed pad, ISL99380BFRZ-TR5935 achieves ≤70°C case temperature rise at 80A DC with 12V input and 1.0V output. Its 5x6 mm QFN package and integrated 8mV/°C TOUT output enable direct die temperature monitoring - a capability confirmed in Renesas' thermal characterization reports for ISL99380BFRZ-TR5935.
Is ISL99380BFRZ-TR5935 pin-compatible with ISL99380R5935?
Yes, ISL99380BFRZ-TR5935 and ISL99380R5935 share identical pinout, package dimensions, and terminal functions - differing only in PWM input logic level (5V vs. 3.3V) and associated internal biasing. This allows drop-in replacement in existing layouts when migrating from ISL99380R5935 to ISL99380BFRZ-TR5935, provided the controller's PWM voltage level matches the selected variant.
