Product details
Overview
The MAX17482GTL+ from Maxim Integrated is a dual-phase, Quick-PWM™ step-down VID power-supply controller designed for IMVP-6.5-compliant notebook CPU core supplies. It delivers ±0.5% output voltage accuracy over line/load/temperature, supports 7-bit VID (0–1.50V), and features active voltage positioning, programmable 200–800kHz switching frequency, and integrated boost switches for synchronous rectifier MOSFET drive.
For engineers reviewing the MAX17482GTL+ datasheet, MAX17482GTL+ pinout, MAX17482GTL+ application, or MAX17482GTL+ equivalent, this controller is selected for high-efficiency, low-ripple multiphase CPU core regulation in thermally constrained mobile platforms requiring precise dynamic phase selection, differential current sensing, and thermal-fault monitoring via VRHOT.
Technical Context
The MAX17482GTL+ implements true out-of-phase interleaved operation across two phases to reduce input ripple current and output voltage ripple-enabling smaller input/output capacitors and relaxed PCB layout constraints. Its Quick-PWM control architecture provides instantaneous response to fast load transients typical of modern CPUs.
It integrates a slew-rate controller for controlled VID transitions, soft-start/shutdown, and suspend-exit timing; a thermistor-based VRHOT thermal-fault output; and an analog current monitor (IMON) proportional to total CPU power consumption. Differential current sense and PHASEGD fault detection ensure balanced phase current sharing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Accuracy | ±0.5% over line, load, and temperature - ensures stable CPU VDD under dynamic workloads without recalibration. |
| VID Range | 7-bit (0–1.50V) - supports full IMVP-6.5 voltage scaling for Intel Calpella-era processors. |
| Switching Frequency | Programmable 200–800kHz - enables optimization between efficiency (low-freq) and transient response/component size (high-freq). |
| Input Voltage Range | 4V to 26V battery input - compatible with wide-range notebook and ultrabook power architectures. |
| Current Monitor Output | IMON analog current output (93.12–98.88μA at full load) - enables real-time CPU power telemetry without external shunts. |
| Thermal Fault Threshold | VRHOT trip at 28–32% of VCC - provides scalable, resistor-programmable thermal shutdown using standard NTC thermistors. |
| Phase-Good Detection | PHASEGD output asserts on >1.25mV current imbalance - prevents asymmetric phase loading and thermal runaway. |
Pinout & Package
The MAX17482GTL+ is housed in a 5mm × 5mm, 40-pin TQFN-EP package with exposed pad connected to GND for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| CSP1/CSN1, CSP2/CSN2 | Differential current sense inputs (per phase) | Enable true valley-current limiting and phase current balancing with ±1.25mV offset. |
| IMON | Analog current monitor output | Provides 2.2–2.6mS transconductance output proportional to total CPU current (MAX17482 only). |
| VRHOT | Thermal fault open-drain output | Asserts low when THRM pin voltage drops below 28–32% of VCC - connects directly to system thermal interrupt. |
| PHASEGD | Phase imbalance fault indicator | Open-drain output asserting on >1.25mV inter-phase current difference - triggers system-level fault handling. |
| PWRGD | Power-good status output | Signals regulated output (±250mV window) with 3–10ms startup delay - used for CPU reset sequencing. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-phase CPU core controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX17082GTL+ | Pin-compatible, identical IMVP-6.5 support, same package and pinout - differs only in internal mask revision and minor characterization. | No functional difference in notebook or blade server use; both support IMON, VRHOT, PHASEGD, and identical VID range. | Select MAX17082GTL+ when legacy qualification or specific wafer lot traceability is required; otherwise interchangeable with MAX17482GTL+. |
| ISL95210IRZ-T | Single-chip 2-phase controller with integrated MOSFET drivers and PMBus interface; lacks IMON output and uses SMBus instead of discrete VRHOT/PHASEGD signals. | Suitable for systems requiring digital telemetry and firmware-controlled thermal management, but requires redesign for analog fault signaling. | Choose ISL95210IRZ-T only if PMBus communication, programmable loop compensation, or integrated driver FETs are mandatory - not a drop-in replacement. |
Compared with MAX17082GTL+, the MAX17482GTL+ offers identical electrical behavior and qualification; compared with ISL95210IRZ-T, it provides simpler analog fault signaling and lower BOM cost but no digital configurability - making it optimal for cost-sensitive, analog-architected IMVP-6.5 platforms.

FAQ
What is the supported IMVP specification for the MAX17482GTL+?
The MAX17482GTL+ supports the IMVP-6.5 specification, targeting Intel Calpella-generation mobile processors. It implements all required VID codes (0–1.50V), active voltage positioning, thermal fault signaling via VRHOT, and phase-good monitoring - fully compliant with IMVP-6.5 timing, accuracy, and protection requirements as verified in Maxim's datasheet Rev 2.
Does the MAX17482GTL+ include an integrated current monitor output?
Yes, the MAX17482GTL+ includes an analog current monitor (IMON) output that delivers 93.12–98.88μA at full load, with 2.2–2.6mS transconductance. This feature is exclusive to MAX17082GTL+ and MAX17482GTL+ variants - the MAX17021GTL+ does not provide IMON. The output enables real-time CPU power measurement without external shunt resistors.
What package type and thermal characteristics does the MAX17482GTL+ use?
The MAX17482GTL+ uses a 5mm × 5mm, 40-pin TQFN-EP package with exposed pad connected to GND. At +70°C, its continuous power dissipation is 1778mW, derating at 22.2mW/°C above that temperature. The junction-to-ambient thermal resistance (θJA) is optimized for compact notebook PCB layouts with single-layer thermal vias to internal ground planes.
How does the MAX17482GTL+ handle thermal protection?
The MAX17482GTL+ provides dual thermal protection: a programmable VRHOT output that asserts low when the THRM pin voltage falls below 28–32% of VCC (typically interfaced with an NTC thermistor), and a hard thermal shutdown at 160°C (TSHDN). Both functions are fully specified across –40°C to +105°C operating range and require no external components beyond the thermistor and pull-up resistor.
Can the MAX17482GTL+ operate in single-phase mode?
No, the MAX17482GTL+ is a fixed dual-phase controller and does not support single-phase operation. However, it implements dynamic phase selection - automatically disabling Phase 2 during light loads to improve light-load efficiency. Phase 2 re-enables within microseconds upon load increase, maintaining seamless transition without CPU interruption or BIOS involvement.
