Product details
Overview
ISL62884CHRTZ-T from Renesas (formerly Intersil) is a single-phase PWM buck regulator IC designed for IMVP-6™-compliant microprocessor core power supplies in mobile computing platforms. It integrates high- and low-side gate drivers, supports 7-bit VID input (0–1.500 V in 12.5 mV steps), delivers ±0.5% system voltage accuracy over temperature, uses Robust Ripple Regulator (R3™) modulation, and enables diode emulation mode via DPRSLPVR control.
For engineers reviewing the ISL62884CHRTZ-T datasheet, ISL62884CHRTZ-T pinout, ISL62884CHRTZ-T application, or ISL62884CHRTZ-T equivalent, key selection criteria include IMVP-6™ compliance, differential remote sensing capability, DCR/resistor current sensing flexibility, adaptive body diode conduction time reduction, and user-selectable overshoot reduction for capacitor optimization.
Technical Context
The ISL62884CHRTZ-T implements Intersil's R3™ modulator architecture, enabling variable-frequency operation during load transients to achieve faster response while reducing switching frequency at light loads for higher efficiency. It interprets DPRSLPVR signals to enter/exit diode emulation mode and reports real-time output current via the IMON pin.
Differential remote voltage sensing compensates for PCB IR drop, ensuring accurate die-level regulation. Current sensing supports both lossless inductor DCR with NTC-based thermal compensation and precision shunt resistors - both validated under IMVP-6™ transient and accuracy requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar single-phase IMVP-6™-compliant CPU core regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL62883HRTZ-T | 3-phase capable; includes phase-interleaving control and additional current-sense amplifiers | Targeted for higher-current CPUs (>30 A); requires more layout area and external MOSFETs per phase | Select ISL62883HRTZ-T only when >22 A continuous output current or multiphase coordination is required |
| RT8803AZSP | No integrated gate drivers; requires external high-side/low-side drivers; supports IMVP-7/8 but not IMVP-6™-specific DPRSLPVR logic | Used in newer platform generations; lacks native diode emulation trigger and IMON reporting per IMVP-6™ spec | Choose RT8803AZSP only for IMVP-7/8 migration paths where legacy IMVP-6™ signaling is not needed |
Compared with ISL62884CHRTZ-T, ISL62883HRTZ-T offers scalable multiphase support but increases BOM count and layout complexity, while RT8803AZSP targets next-gen platforms with different VID encoding and no DPRSLPVR compatibility - making ISL62884CHRTZ-T the only validated fit for IMVP-6™-constrained designs requiring single-phase integration and diode emulation.

FAQ
What is the maximum supported output current for ISL62884CHRTZ-T?
The ISL62884CHRTZ-T is rated for continuous output currents up to 22 A, as verified in the FN7591 datasheet load line plot (Page 2) and thermal performance characterization under 19 V input. Its R3™ modulator and integrated gate drivers sustain this current with appropriate external MOSFET selection and PCB copper area, meeting IMVP-6™ transient response requirements across the full range.
Does ISL62884CHRTZ-T support diode emulation mode, and how is it activated?
Yes, ISL62884CHRTZ-T supports diode emulation mode per IMVP-6™ specification. It is activated by asserting the DPRSLPVR pin low, which disables synchronous rectification and enables controlled body-diode conduction. The IC automatically reduces body diode conduction time using internal adaptive timing to minimize reverse recovery losses without external components.
Can ISL62884CHRTZ-T use inductor DCR sensing without external compensation components?
No - inductor DCR sensing with thermal compensation requires an external NTC thermistor connected to the THERM pin, as specified in FN7591 Section 3.3. The ISL62884CHRTZ-T provides internal circuitry to interpret the NTC voltage and adjust DCR gain accordingly, but the thermistor itself is mandatory for accurate temperature compensation across −10°C to +105°C.
What is the purpose of the IMON pin on ISL62884CHRTZ-T?
The IMON pin on ISL62884CHRTZ-T outputs an analog voltage (typically 10 mV per ampere) proportional to the output current, enabling real-time current monitoring, overcurrent protection, and telemetry reporting to the system controller. This feature is required by IMVP-6™ for processor power state coordination and thermal management.
Is ISL62884CHRTZ-T pin-compatible with earlier ISL62884 variants like ISL62884A or ISL62884B?
No - ISL62884CHRTZ-T is not pin-compatible with ISL62884A or ISL62884B. While sharing the same 28-pin TQFN package outline, the C-grade revision introduces updated DPRSLPVR timing, refined R3™ modulator behavior, and modified IMON scaling. Migration requires validation per FN7591 Rev 0.00 and may necessitate layout or firmware updates.
