Product details

Overview

P9145-I0NQGI from Integrated Device Technology is a programmable multi-channel PMIC for Intel® Atom™ SoCs, integrating seven current-mode step-down converters (up to 2 MHz switching), seven general-purpose LDOs, SVID interface compliant with IMVP7 protocol, 10-bit ADC, and 16 GPIOs - deployed in client computing power delivery subsystems.

For engineers reviewing the P9145-I0NQGI datasheet, P9145-I0NQGI pinout, P9145-I0NQGI application, or P9145-I0NQGI equivalent, key selection factors include SVID-controlled VCC/VNN/VDDQ rail management, OTP-programmable power sequencing, scalable output current via IDTP9147 add-on sources, and high-speed I²C host interface support.

Technical Context

The P9145-I0NQGI implements dual-interface control: SVID handles real-time voltage ID negotiation and system control signals for VCC, VNN, and VDDQ rails per IMVP7, while high-speed I²C manages configuration, monitoring, and non-volatile OTP programming of power sequences and settings. It supports distributed architecture via dedicated interface for IDTP9147 add-on power sources.

Power regulation includes seven synchronous buck converters operating at 2.0 MHz with current-mode control, seven independent LDOs, 12 programmable enable outputs, and integrated 10-bit ADC for system telemetry - all coordinated through centralized state-machine-based power sequencing logic.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	4.5 V to 5.5 V - supports standard 5 V system rail with ±10% tolerance for robustness against supply variation.
Switching Frequency	2.0 MHz - enables use of compact external inductors and capacitors, reducing solution footprint in space-constrained Atom SoC platforms.
Buck Regulators	7 channels - provides independent, current-mode controlled DC/DC conversion for core, memory, and I/O rails in Intel Atom systems.
LDO Regulators	7 channels - delivers low-noise, fast-transient auxiliary supplies for analog, reference, or always-on circuitry without switching noise coupling.
SVID Compliance	IMVP7 - enables dynamic voltage scaling and bidirectional communication with Intel Atom SoC for precise VCC/VNN/VDDQ rail control.
I²C Interface	High-speed mode (up to 3.4 Mbps) - allows rapid configuration updates, telemetry reads, and OTP programming during system initialization or runtime.

Alternative Part	Technical Difference	Application Difference	Selection Advice
RTQ2136B-QA	6-channel buck + 4-channel LDO; no SVID interface; supports I²C only; lower integration (no ADC, fewer GPIOs)	Targeted at automotive infotainment SoCs (AEC-Q100 Grade 2); lacks IMVP7 compliance and distributed power extension	Select when automotive qualification and functional safety features outweigh need for Intel-specific SVID control.
TPS6521905RSLR	6-buck + 4-LDO + 10-bit ADC + 12 GPIOs; supports I²C and PMBus; no SVID; fixed internal sequencing (non-OTP)	Optimized for TI Sitara AM6x processors; uses PMBus for telemetry; no native Intel SoC protocol support	Prefer for Sitara-based designs requiring PMBus compatibility and pre-validated thermal management profiles.

FAQ

What is the primary function of the P9145-I0NQGI in Intel Atom systems?

The P9145-I0NQGI serves as the central power management IC for Intel Atom SoCs, providing regulated voltage rails (7 bucks + 7 LDOs), IMVP7-compliant SVID communication for VCC/VNN/VDDQ control, OTP-programmable sequencing, and system telemetry via its 10-bit ADC and 16 GPIOs. Its design directly supports Intel's power architecture requirements without external sequencers or supervisors.

Does the P9145-I0NQGI support distributed power scaling, and how is it implemented?

Yes, the P9145-I0NQGI supports distributed power scaling through a dedicated interface for IDTP9147 add-on power sources. This allows system designers to increase total output current capacity beyond the monolithic limits of the P9145-I0NQGI alone, enabling flexible SKU differentiation while retaining identical mainboard layout and firmware.

What interfaces does the P9145-I0NQGI provide, and what are their roles?

The P9145-I0NQGI provides two critical interfaces: an IMVP7-compliant SVID interface (SVID_SCLK/SVID_SDATA) for real-time voltage ID negotiation and system control with the Intel Atom SoC, and a high-speed I²C interface (I2C_SDA/I2C_SCL) for configuration, telemetry readback, OTP programming, and fault monitoring - both essential for full system power management.

Is the power sequencing behavior of the P9145-I0NQGI fixed or programmable?

The power sequencing behavior of the P9145-I0NQGI is fully OTP-programmable. Users can define custom startup/shutdown order, timing delays, and dependency relationships for all 7 buck regulators, 7 LDOs, and 12 enable outputs - stored in on-chip one-time-programmable memory, ensuring deterministic behavior without host CPU involvement during boot.

What package type and thermal characteristics does the P9145-I0NQGI use?

The P9145-I0NQGI uses a 100-lead 8 mm × 8 mm dual-row VFQFPN package (NQG100 code) with an exposed thermal pad. It is rated for industrial temperature range (–40°C to +85°C), supports RoHS compliance, and is optimized for efficient heat dissipation in compact client and embedded platforms where airflow is limited.
