Product details
Overview
P9145-I0NQGI8 from Renesas (formerly IDT) is a programmable multi-channel PMIC for Intel® Atom™ SoCs, integrating seven current-mode step-down converters, seven LDOs, a 10-bit ADC, 16 GPIOs, and SVID interface supporting IMVP7 protocol. It delivers scalable power delivery with OTP-programmable sequencing and supports distributed power expansion via IDTP9147 add-on sources in compact computing platforms.
For engineers reviewing the P9145-I0NQGI8 datasheet, P9145-I0NQGI8 pinout, P9145-I0NQGI8 application, or P9145-I0NQGI8 equivalent, key selection factors include IMVP7-compliant SVID control, dual-row 100-pin 8×8mm QFN package, 4.5–5.5V input range, 2MHz switching frequency, and configurable enable outputs for complex power sequencing in embedded Atom-based systems.
Technical Context
The P9145-I0NQGI8 implements a host-controlled power architecture where the Intel Atom SoC communicates via high-speed I²C for configuration and monitoring, while SVID handles real-time VCC/VNN/VDDQ rail voltage and control signal negotiation. Its seven buck regulators operate in current-mode control with 2MHz fixed-frequency switching, enabling fast transient response and small external inductor sizing.
Power sequencing is defined by OTP-programmable defaults and dynamically adjustable via I²C or SVID; the integrated 10-bit ADC monitors system voltages and temperatures, and 12 programmable enable outputs coordinate external power stages or subsystems without additional logic.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar multi-channel PMIC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RTQ2136B-QA | 6-channel buck + 4-channel LDO; no SVID; I²C-only interface; 1.2MHz max switching frequency. | Lacks IMVP7/SVID support-requires host MCU to emulate voltage ID negotiation; not suitable for Intel Atom platforms requiring native SVID handshake. | Select when SVID is unnecessary and lower channel count suffices for ARM-based designs with simpler sequencing needs. |
| TPS650944RGER | 6-buck + 6-LDO; supports PMBus v1.3; includes dedicated DDR termination regulator; no OTP sequencing memory. | Relies on external EEPROM or host for sequence definition; lacks built-in IMVP7 protocol engine-requires software stack adaptation for Intel compatibility. | Prefer for TI ecosystem designs with DDR4/LPDDR4 memory where PMBus telemetry and flexible firmware updates outweigh native SVID convenience. |
Compared with RTQ2136B-QA and TPS650944RGER, the P9145-I0NQGI8 uniquely integrates IMVP7 SVID as a hardware-native interface, provides OTP-stored power sequences for zero-host-dependency boot, and supports distributed current scaling via IDTP9147-making it the only option qualified for Intel Atom SoC reference power delivery without protocol translation layers or external sequencing logic.

FAQ
What is the primary function of the P9145-I0NQGI8 in an Intel Atom system?
The P9145-I0NQGI8 serves as the central power management IC for Intel Atom SoCs, providing seven programmable buck regulators, seven LDOs, SVID-based voltage control, and OTP-defined power sequencing. It directly interfaces with the SoC via SVID and I²C to manage core, memory, and I/O rail voltages while enabling dynamic voltage scaling and thermal monitoring-all within the P9145-I0NQGI8's integrated architecture.
Does the P9145-I0NQGI8 support IMVP7-compliant SVID communication?
Yes, the P9145-I0NQGI8 includes a hardware SVID interface fully compliant with IMVP7 specifications, enabling native bidirectional communication with Intel Atom processors for real-time voltage ID updates, VR ready signaling, and thermal alert reporting. This eliminates the need for external protocol translators or firmware emulation layers in the P9145-I0NQGI8-based design.
Can the P9145-I0NQGI8 be used without an external microcontroller for power sequencing?
Yes-the P9145-I0NQGI8 features OTP-programmable default power sequences that execute autonomously at power-on, eliminating dependency on host firmware or external MCUs. This capability ensures reliable, repeatable startup behavior in headless or safety-critical applications where the P9145-I0NQGI8 operates independently until host control is established via I²C or SVID.
What package type and pin count does the P9145-I0NQGI8 use?
The P9145-I0NQGI8 uses a 100-pin VFQFPN (NQG100) package measuring 8 mm × 8 mm with 0.4 mm pitch and dual-row layout. It includes an exposed thermal pad for enhanced heat dissipation and is supplied in tape-and-reel format (P9145-I0NQGI8), distinguishing it from the tray-packaged P9145-I0NQGI variant-both share identical electrical and thermal specifications.
How does the P9145-I0NQGI8 support scalable current delivery beyond its integrated regulators?
The P9145-I0NQGI8 supports scalable current delivery through its native interface with IDTP9147 distributed power sources, which connect via dedicated control and current-sharing buses. This allows parallel addition of external buck modules to increase output current per rail without redesigning the P9145-I0NQGI8's core layout-enabling modular power architecture expansion while maintaining centralized sequencing and monitoring via the P9145-I0NQGI8.
