Product details
Overview
MP62160DD-LF-Z from Monolithic Power Systems is a single-channel, active-low enable, current-limited power distribution switch with integrated 85mΩ MOSFET, 2A continuous load capability, 2.8A typical current limit, and output discharge function. It operates from 2.7V to 5.5V input and delivers precise over-current protection in USB power distribution and portable device rail switching.
For engineers reviewing the MP62160DD-LF-Z datasheet, MP62160DD-LF-Z pinout, MP62160DD-LF-Z application, or MP62160DD-LF-Z equivalent, key selection criteria include its 8ms FLAG deglitch time, reverse current blocking, thermal shutdown threshold at 140°C, and QFN8E (2mm × 3mm) package with exposed thermal pad tied to GND.
Technical Context
The MP62160DD-LF-Z implements a constant-current limiting architecture triggered at 2.8A typical trip current, entering regulated mode before thermal shutdown activates at 140°C junction temperature. Its open-drain FLAG pin asserts after an 8ms deglitch delay only during sustained over-current events-not during power-up or UVLO transitions.
It integrates under-voltage lockout (UVLO) with 1.95V rising-edge threshold and 250mV hysteresis, plus internal discharge resistance of 250Ω for rapid output capacitor bleed-down when disabled. The device supports reverse current blocking and maintains <1μA shutdown current at 5.5V IN.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 2A - Sustained load handling without derating at TA ≤ +85°C in QFN8E package |
| Current Limit | 2.8A typical - Precise trip point enabling robust short-circuit protection with minimal false triggering |
| RDS(on) | 75–120mΩ - Low conduction loss ensuring <240mV drop at 2A, minimizing thermal stress |
| Supply Range | 2.7V to 5.5V - Direct compatibility with 3.3V and 5V system rails, including USB VBUS |
| Quiescent Current | 90μA typical - Enables low-power standby in battery-operated portable systems |
| FLAG Deglitch Time | 8ms - Eliminates transient fault reporting while retaining fast response to genuine overloads |
| Discharge Resistance | 250Ω - Provides controlled, sub-10ms output capacitor discharge upon disable |
| Thermal Shutdown | 140°C with 20°C hysteresis - Self-recovering protection that prevents permanent silicon damage |
Pinout & Package
MP62160DD-LF-Z uses a QFN8E (2mm × 3mm) thermally enhanced package with exposed pad soldered to PCB ground plane for optimal thermal performance. Pin 1 is marked by a dot or beveled corner per JEDEC MO-229 VCED-2.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power and signal reference; connects to exposed thermal pad for heat dissipation |
| 2,3 | IN | Input voltage supply (2.7–5.5V); accepts decoupling capacitor ≥10μF |
| 4 | EN | Active-low enable control; logic low (<0.8V) enables switch, high (>2V) disables |
| 5 | FLAG | Open-drain fault indicator; pulls low after 8ms deglitched over-current detection |
| 6,7,8 | OUT | Power output terminals (parallel-connected); deliver switched IN-to-OUT path with discharge path enabled on disable |
Key Features
| Feature | Design Value |
|---|---|
| Output Discharge Function | Integrated 250Ω discharge path automatically engages on disable, clearing output capacitance within milliseconds |
| Reverse Current Blocking | Prevents backflow from OUT to IN when disabled-critical for multi-rail isolation in USB and hot-swap applications |
| No FLAG Glitch During Power-Up | FLAG remains high-z until valid operation established, eliminating false fault assertions during system boot |
| Under-Voltage Lockout (UVLO) | 1.95V turn-on threshold with 250mV hysteresis ensures clean enable/disable behavior across input brownout conditions |
| Thermal-Shutdown Recovery | Auto-restart at ~120°C junction temperature enables self-healing behavior after overload removal |
| UL Recognition | E322138 certified - meets safety requirements for end-equipment integration without additional isolation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar current-limited power distribution switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TPS22965DRLR | 2A continuous, 2.7A current limit, 44mΩ RDS(on), no integrated discharge resistor | Lacks output discharge; requires external RC network for capacitor bleed-down | Preferred where lower on-resistance justifies added BOM cost and layout area |
| ON Semi NIS5132MN | 2A continuous, 2.5A current limit, 100mΩ RDS(on), 1.8–5.5V supply range | Narrower UVLO (1.8V), higher RDS(on), no FLAG deglitch specification | Suitable for cost-sensitive designs with relaxed fault timing requirements and margin on voltage headroom |
Compared with TPS22965DRLR and NIS5132MN, MP62160DD-LF-Z uniquely combines integrated 250Ω discharge, 8ms deglitch, and UL recognition in a 2mm × 3mm QFN-enabling compact, safety-certified, and maintenance-free USB/PCB rail switching without external components.

FAQ
What is the function of the FLAG pin, and how does its deglitching work?
The FLAG pin is an open-drain output that asserts low only after a sustained over-current condition exceeds the 8ms internal deglitch timer-preventing false triggers from inrush or transient spikes. It remains inactive during power-up, UVLO, or thermal events, and requires an external pull-up resistor to function correctly in system monitoring circuits.
Does MP62160DD-LF-Z support reverse current blocking, and under what conditions?
Yes-MP62160DD-LF-Z blocks reverse current flow from OUT to IN when disabled or when IN falls below UVLO threshold. This occurs due to internal MOSFET body diode isolation and active gate control, verified at 5.5V OUT and GND IN, with leakage <0.2μA per datasheet test conditions.
Can MP62160DD-LF-Z be used with 3.3V-only systems, and what is its minimum operating voltage?
Yes-it operates down to 2.7V input, making it fully compatible with 3.3V rails. Its UVLO turns on at 1.95V (rising edge), but functional regulation begins at 2.7V, with guaranteed 2A continuous current and 2.8A current limit across the full 2.7–5.5V range per electrical characteristics table.
How does the output discharge function behave during disable, and what is its effective resistance?
Upon disable (EN low or IN < UVLO), an internal 250Ω resistor connects OUT to GND, discharging typical 10–100μF output capacitors in under 10ms. This eliminates floating voltages and prevents unintended wake-up or latch-up in downstream circuitry, with no external components required.
Is thermal shutdown recovery automatic, and what is the hysteresis value?
Yes-thermal shutdown is fully autonomous. The device shuts off at 140°C junction temperature and resumes operation once die temperature cools to approximately 120°C, yielding a 20°C hysteresis confirmed in absolute maximum ratings and functional description sections of the datasheet.
What package variants exist for MP62160, and which one corresponds to MP62160DD-LF-Z?
MP62160 is offered in SOIC8 (MP62160DS), MSOP8E (MP62160DH), and QFN8E (MP62160DD). The "DD" suffix denotes the QFN8E (2mm × 3mm) variant with exposed thermal pad; "-LF" indicates lead-free/halogen-free RoHS compliance, and "-Z" specifies tape-and-reel packaging-hence MP62160DD-LF-Z is the RoHS-compliant QFN8E in tape-and-reel.
Does MP62160DD-LF-Z require input or output capacitors, and what values are recommended?
Yes-a minimum 10μF ceramic capacitor is recommended between IN and GND to suppress supply transients and improve short-circuit immunity. For heavy loads, a high-value electrolytic capacitor (e.g., 100μF) on OUT reduces ripple; both values are specified in the Application Information section of the datasheet.
