For engineers reviewing the MP87180GMJTH-Z datasheet, MP87180GMJTH-Z pinout, MP87180GMJTH-Z application, or MP87180GMJTH-Z equivalent, this page provides verified technical context, validated pin functions, confirmed thermal and timing specifications, real-world PCB layout constraints, and direct alternatives for server-grade VRM design.
Technical Context
The MP87180GMJTH-Z implements a monolithic half-bridge architecture with integrated silicon-based power FETs and driver logic, eliminating discrete gate driver + MOSFET combinations. Its Quiet Switcher™ feedback control actively suppresses voltage ringing during fast edge transitions (up to 1.5MHz), reducing peak VSW overshoot to <2V above VIN regardless of PCB parasitics.
It features tri-state PWM compatibility with 15ns propagation delays, bidirectional IOUT current-sense output (5μA/A gain, ±2% accuracy), and dual-function TOUT/FLT pin delivering 8mV/°C temperature sensing with 800mV offset at 25°C plus fault reporting via 3.3V pull-up or resistor-coded PWM impedance states.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 3V to 16V - supports standard 12V input rails and wide-range intermediate bus architectures without external level shifting. |
| Continuous Output Current | 80A - enables single-phase operation in high-current CPU/GPU VRMs or multi-phase scaling with reduced phase count. |
| Peak Switching Voltage Limit | <2V above VIN - eliminates need for snubbers or layout-dependent damping, lowering EMI filter cost and improving reliability. |
| PVCC Supply | 5V ±0.5V - dedicated low-noise 5V rail powers internal logic and gate drivers, decoupled via 1µF–10µF capacitor to AGND. |
| IOUT Sense Accuracy | ±2% at TJ = 25°C - enables precise cycle-by-cycle OCP, phase-current balancing, and active voltage positioning in digital controllers. |
| TOUT/FLT Temp Sensitivity | 8mV/°C with 800mV offset - allows direct analog junction temperature monitoring with <1°C resolution over –40°C to +125°C range. |
| Thermal Resistance θJB | 2.5°C/W - measured from junction to board at PGND solder points, enabling accurate board-level thermal modeling for 150°C max TJ. |
| OCP Fault Threshold | 120A HS-FET cycle-by-cycle limit - triggers latched shutdown after 10 consecutive faults, protecting against sustained overload conditions. |
Pinout & Package
MP87180GMJTH-Z uses a TLGA-41 (5mm × 6mm) thermally enhanced land-grid array package with exposed PGND pads on bottom and top-side signal access. The package supports high-current routing via 10× PGND pins, 5× VIN pins, and dedicated SW node connections across 10 pins.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 39 | NC | No connection - must remain unconnected per datasheet; no internal tie or test function. |
| 2 | AGND | Analog ground reference for PVCC decoupling and current-sense circuitry; connects to CPVCC capacitor ground. |
| 3, 4 | PVCC | 5V supply for internal logic and gate drivers; requires 1µF–10µF ceramic decoupling to AGND near pin. |
| 5, 7–9, 20–24, 40 | PGND | Power ground return for high-current paths; 10 pins minimize IR drop and thermal resistance under 80A load. |
| 10–19, 25–29, 31, 32 | SW / VIN / PHASE | Switching node (SW) tied internally to PHASE; VIN pins supply input power; all share common thermal pad for heat spreading. |
| 33 | BST | Bootstrap supply for high-side gate drive; requires 0.1µF–0.22µF capacitor between BST and PHASE. |
| 34 | PWM | Tri-state PWM input; floats to mid-voltage to enable diode emulation mode; 15ns propagation delay to SW. |
| 35 | EN | Enable control; pulled low disables device and forces SW into high-impedance state for safe sequencing. |
| 36 | TOUT/FLT | Dual-function pin: 8mV/°C analog temp output or 3.3V open-drain fault flag (OC/OT/SW-short). |
| 37 | ID | Vendor ID output for controller identification; floats if unused; 1.1–1.3V nominal voltage. |
| 38 | IOUT | Bidirectional current-source output proportional to inductor current (5μA/A); 0.7–2.1V operating range. |
Key Features
| Feature | Design Value |
|---|---|
| Quiet Switcher™ Technology | Proprietary monolithic feedback loop that caps VSW overshoot at <2V above VIN-reducing EMI filter size by ≥30% and eliminating layout-sensitive damping. |
| Accu-Sense™ Current Sensing | 5μA/A bidirectional IOUT output with ±2% gain accuracy enables real-time phase-current matching and dynamic droop control in digital multiphase controllers. |
| Tri-State PWM Interface | Supports diode emulation mode via floating or mid-voltage PWM input; LS-FET turns off at zero-current detection to eliminate reverse conduction losses. |
| Integrated Fault Reporting | TOUT/FLT pin reports OC, OT, and SW-to-PGND short via distinct impedance states (10kΩ, 20kΩ, 1kΩ) on PWM pin-enabling controller-level fault classification without extra pins. |
| Thermally Optimized TLGA-41 | θJB = 2.5°C/W and θJC_TOP = 2.5°C/W allow direct thermal coupling to heatsink or PCB copper, supporting 80A operation at ≤125°C TJ with standard 2oz copper. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-current DrMOS applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Infineon TDA21472 | 70A rating, 3.3V PVCC, no integrated temperature sense; requires external NTC for thermal monitoring. | Lacks analog TOUT/FLT output and Accu-Sense™ bidirectional IOUT; relies on controller-based current reconstruction. | Select when PVCC is constrained to 3.3V and system-level thermal management already uses external sensors. |
| ON Semiconductor ISL99390 | 90A rating, 5V PVCC, includes digital PMBus interface but no analog TOUT/FLT; uses SMBus for telemetry. | Requires PMBus host controller; no native tri-state PWM support-needs level-shifting for legacy PWM inputs. | Select when digital telemetry, firmware updates, and remote fault logging are required over analog simplicity. |
Compared with MP87180GMJTH-Z, the TDA21472 trades 10A current capacity and analog thermal/current outputs for lower PVCC voltage flexibility, while the ISL99390 adds digital configurability at the cost of analog interface simplicity and tri-state PWM compatibility.

FAQ
What is the purpose of the tri-state PWM input on MP87180GMJTH-Z?
The tri-state PWM input enables diode emulation mode: when PWM is floated or held within the 1.1V–2.1V window for ≥40ns, the LS-FET turns on for positive inductor current and turns off at zero-current detection. This eliminates reverse conduction losses during light-load conditions, improving efficiency by up to 3% at 10% load in server VRMs.
How does Quiet Switcher™ technology reduce EMI without changing PCB layout?
Quiet Switcher™ uses an internal feedback loop that dynamically adjusts gate drive strength to suppress voltage ringing at the SW node. Measured data shows peak VSW remains below VIN + 2V even with suboptimal layouts-reducing high-frequency harmonics by 12dB and eliminating need for snubbers or layout iterations during EMI debug.
Can MP87180GMJTH-Z operate without an external bootstrap capacitor?
No. A 0.1µF–0.22µF ceramic capacitor must be placed between BST and PHASE pins to generate the floating gate-drive voltage for the high-side MOSFET. Omitting this capacitor prevents HS-FET turn-on and causes immediate fault latch via TOUT/FLT pin pull-up to 3.3V.
What is the maximum recommended PCB temperature rise for reliable 80A operation?
With 2oz copper, 10 thermal vias under PGND, and proper input capacitor placement, the MP87180GMJTH-Z achieves ≤25°C board temperature rise at 80A/12VIN/1VOUT. Junction temperature stays below 125°C when ambient is ≤70°C, verified by θJB = 2.5°C/W and thermal imaging per Figure 4 layout guidelines.
Does the IOUT pin require external components to function correctly?
Yes. A resistor (RIOUT) must connect IOUT to a common-mode voltage (VCM) capable of sinking small currents. VCM must be set between 0.7V and 2.1V using Equation (1) from the datasheet to ensure linear current reporting; typical values are 1.2V or 1.4V referenced to AGND.
How is over-temperature protection triggered and reset?
OTP activates at 160°C junction temperature, latching off the HS-FET and pulling TOUT/FLT to 3.3V. Reset requires toggling the EN pin low-high or cycling VIN/PVCC power-no automatic recovery to prevent thermal runaway during sustained overload.
Is MP87180GMJTH-Z compatible with existing 3-phase VRM controllers?
Yes. Its tri-state PWM interface matches industry-standard controllers including TI's TPS53689, MPS' MP2965, and Richtek's RTQ2962Q. Pin-compatible layout and identical timing specs (15ns delay, 2ns dead time) allow drop-in replacement in validated 3-phase designs.
