Product details

Overview

MP5075GTF-Z from Monolithic Power Systems is a 5.5V, 2.4A integrated load switch with 38mΩ R_DS(ON), fixed 450μs soft-start, output discharge, and thermal/short-circuit protection. It operates from 3V–5.5V input, delivers up to 3A current limit, and is used in USB power distribution and portable SSDs where inrush control and space-constrained board layout are critical.

For engineers reviewing the MP5075GTF-Z datasheet, MP5075GTF-Z pinout, MP5075GTF-Z application, or MP5075GTF-Z equivalent, key selection criteria include its SOT563 package footprint, <5µA shutdown current, 200ns short-circuit response, integrated 150Ω discharge resistor, and EN pin with 1MΩ internal pull-down for robust enable control.

Technical Context

The MP5075GTF-Z implements a sense-FET current-limit architecture with dual-stage overcurrent protection: primary 3A constant-current regulation (20µs response) and secondary fast-turn-off at ~7A (200ns total response). Its charge-pump gate driver enables low R_DS(ON) without external bias.

It integrates UVLO (2.6V rising threshold, 200mV hysteresis), thermal shutdown (150°C trip, 30°C hysteresis), and fixed soft-start (450μs ramp) - all operating autonomously without external components or configuration pins.

Key Specifications

Parameter	Value and Actual Design Meaning
V_IN Range	3V to 5.5V - supports single-cell Li-ion and USB 5V rails without level-shifting
R_DS(ON)	38mΩ @ 5V - minimizes conduction loss (≤45mW at 1.2A) and self-heating in portable devices
I_OUT Limit	Typical 3A - provides headroom above rated 2.4A continuous load for transient surges
Shutdown Current	<5µA - preserves battery life during system sleep modes
Soft-Start Time	450µs - limits inrush dI/dt to ≤6.7A/ms, preventing backplane voltage droop
Short-Circuit Response	<200ns - clamps fault current before PCB trace fusing or upstream supply collapse
Output Discharge R	150Ω - discharges V_OUT to <100mV within ~1ms when disabled under light load

Pinout & Package

MP5075GTF-Z is housed in a 1.6mm × 1.6mm SOT563 package with exposed thermal pad (pin 4 GND connected internally to pad). The package supports high-density routing and efficient heat dissipation via PCB copper area and vias.

Pin/Terminal	Circuit Role	Design Meaning
1, 6 NC	No connection	Must be left floating or tied to GND per layout guidelines; no electrical function
2 VIN	Input power supply	Accepts 3V–5.5V; requires local 10µF ceramic capacitor for stability and ESR filtering
3 VOUT	Switched output to load	Delivers regulated current-limited power; connects to load and output capacitor
4 GND	Power and signal ground	Primary thermal path; must be connected to large copper pour and ≥4 thermal vias
5 EN	Enable control input	Active-high logic; 1.5V threshold with 200mV hysteresis; internal 1MΩ pull-down ensures default OFF state

Key Features

Feature	Design Value
Integrated low-R_DS(ON) MOSFET	38mΩ at 5V enables >98% efficiency at 2A, eliminating discrete FET + driver complexity
Fixed soft-start timing	450µs internal ramp prevents inrush-induced voltage sag on shared 5V rails (e.g., USB hubs)
Dual-stage overcurrent protection	3A current limit + 7A fast-turn-off ensures robustness against both overload and hard shorts
Output discharge function	150Ω internal pull-down safely discharges V_OUT after disable, preventing floating bus states in hot-swap systems
Thermal shutdown with hysteresis	150°C trip / 120°C recovery prevents thermal cycling and enables safe auto-retry after cooling

Applications

USB Power Distribution

Solid-State Drives (SSD)

Use Scenario: Managing power delivery to downstream USB peripherals from a host controller with shared 5V rail.

IC Role / Device Role: Load switch isolating individual USB ports to prevent inrush-induced brownouts across the bus.

Use Value: 450µs soft-start limits dI/dt to protect upstream 5V source; 38mΩ R_DS(ON) keeps voltage drop ≤90mV at 2.4A.

Use Scenario: Enabling/disabling 3.3V or 5V power to NAND flash modules during sleep/wake transitions.

IC Role / Device Role: Controlled power gate with fast turn-off to prevent data corruption during unexpected power loss.

Use Value: <200ns short-circuit response protects SSD controller from latch-up; 150Ω discharge clears residual V_OUT before re-enabling.

Notebook Subsystem Power

Portable Dongles

Use Scenario: Sequencing power to camera, audio codec, or Wi-Fi modules in ultrabooks with strict thermal budgets.

IC Role / Device Role: Low-quiescent, thermally robust load switch enabling subsystem-level power gating.

Use Value: <5µA shutdown current extends battery runtime; 130°C/W θ_JA allows operation up to 125°C junction temp in compact layouts.

Use Scenario: Power management in compact USB-C dongles supporting HDMI, Ethernet, and USB-A ports.

IC Role / Device Role: Space-optimized load switch providing independent port enable/disable with fault isolation.

Use Value: SOT563 footprint (1.6×1.6mm) fits tight dongle PCBs; NC pins simplify routing without sacrificing performance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar load switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TI TPS22916BYFPR	2.7V–5.5V input, 2A rating, 44mΩ R_DS(ON), 1.8µA quiescent, no output discharge	Lacks integrated discharge resistor; requires external circuitry for V_OUT bleed-down	Preferred when ultra-low IQ dominates design priority and discharge is handled externally
ON Semi NCP45561MUTBG	2.5V–5.5V input, 3.6A rating, 20mΩ R_DS(ON), 1.2ms soft-start, no thermal shutdown	Higher current capability but slower soft-start and missing thermal protection	Selected for higher-current loads where thermal margin is managed externally

Compared with TPS22916BYFPR and NCP45561MUTBG, MP5075GTF-Z uniquely balances 3A current limit, 450µs soft-start, integrated discharge, and thermal shutdown in a 1.6mm² footprint-making it optimal for USB-powered portable storage and compact computing subsystems requiring autonomous fault handling.

FAQ

What is the maximum continuous output current supported by MP5075GTF-Z?

The MP5075GTF-Z is rated for 2.4A continuous output current under recommended operating conditions (T_A = +25°C, proper PCB thermal design). Its internal current limit is fixed at 3A typical, allowing brief transients beyond 2.4A while maintaining thermal safety via built-in shutdown at 150°C.

Does MP5075GTF-Z require external components for basic operation?

No external components are required for core functionality. Only two 10µF ceramic capacitors (input and output) are recommended per the typical application circuit. The soft-start time, current limit, and discharge resistance are fully internal and factory-trimmed - no resistors, capacitors, or configuration pins are needed.

How does the output discharge function operate, and when is it active?

The output discharge function activates automatically when EN is pulled low (or left floating), disabling the internal FET. An integrated 150Ω pull-down resistor between VOUT and GND then discharges the output node. This occurs only under light-load conditions (no significant sink path), clearing residual voltage to <100mV within ~1ms to prevent floating bus states.

Can MP5075GTF-Z be used with a 3.3V input supply?

Yes - MP5075GTF-Z supports input voltages from 3V to 5.5V. At 3.3V, R_DS(ON) increases to 48mΩ (vs. 38mΩ at 5V), resulting in ~20% higher conduction loss at full load. All protections (UVLO, OCP, thermal) remain fully functional across the entire range.

What is the purpose of the NC pins (1 and 6) in the SOT563 package?

Pins 1 and 6 are no-connect terminals with no internal bond wires. They may be left unconnected or tied to GND per MPS layout guidelines to improve mechanical stability and simplify routing - but they serve no electrical function and must never be connected to VIN, VOUT, or EN.

Is MP5075GTF-Z compliant with RoHS and halogen-free standards?

Yes - MP5075GTF-Z is lead-free, halogen-free, and fully compliant with the EU RoHS directive. MPS confirms green status for this part on its official Quality Assurance webpage, and the device meets JEDEC MSL-1 moisture sensitivity requirements for standard surface-mount assembly.
