Product details
Overview
MP62160DS-LF-Z from Monolithic Power Systems is a single-channel, active-low enable, current-limited power distribution switch with output discharge function. It integrates an 85mΩ MOSFET, delivers up to 2A continuous load current, features 2.8A typical current limit, thermal shutdown at 140°C, and operates across 2.7V–5.5V input range. Used in USB power distribution and PC card hot-swap circuits where controlled inrush and fault reporting are critical.
For engineers reviewing the MP62160DS-LF-Z datasheet, MP62160DS-LF-Z pinout, MP62160DS-LF-Z application, or MP62160DS-LF-Z equivalent, key selection criteria include its SOIC8 package, active-low EN logic, open-drain FLAG with 8ms deglitch, reverse current blocking, and integrated output discharge resistor (250Ω).
Technical Context
The MP62160DS-LF-Z implements over-current protection via constant-current limiting triggered at ≥3.1A trip threshold, with recovery after thermal shutdown when junction temperature drops to ~120°C. Its UVLO circuit activates below 1.95V (rising edge) with 250mV hysteresis, ensuring stable enable behavior during brown-out conditions.
It uses internal charge-pump gate drive for low RDS(on) (85mΩ typ. at VIN=5V), supports fast turn-on (3ms) and turn-off (10ms) into 100μF/5Ω loads, and provides resistive output discharge (250Ω) activated only during disable or UVLO, eliminating external discharge circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 2A - Sustained load capability without derating at TA ≤ +85°C in SOIC8 package. |
| Current Limit | 2.8A typical - Sets maximum sustained fault current before entering constant-current mode. |
| RDS(on) | 85mΩ max - Low conduction loss enabling <170mV drop at 2A, reducing thermal stress. |
| Supply Range | 2.7V–5.5V - Compatible with 3.3V and 5V system rails, including USB VBUS and notebook standby supplies. |
| Quiescent Current | 90μA typ. - Enables ultra-low standby power in always-on USB ports or hot-swap controllers. |
| FLAG Deglitch | 8ms - Prevents false OCP assertions during transient inrush or brief overload spikes. |
| Discharge Resistance | 250Ω - Actively discharges output capacitors within milliseconds upon disable, meeting USB PD safety timing. |
| Thermal Shutdown | 140°C - Protects die integrity under sustained overload; hysteresis enables automatic recovery at ~120°C. |
Pinout & Package
MP62160DS-LF-Z is housed in an 8-pin SOIC package (body size 3.9mm × 4.9mm) with exposed pad thermally connected to GND. The package supports standard reflow profiles and meets UL recognition E322138.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Power ground reference and thermal path for exposed pad connection. |
| 2,3 | IN | Input voltage supply pin (2.7V–5.5V); accepts dual-source routing for redundancy or sequencing. |
| 4 | EN | Active-low enable input; asserts device when pulled low; high-impedance with 1μA leakage. |
| 5 | FLAG | Open-drain fault indicator; pulls low after 8ms deglitch on OCP or thermal event. |
| 6,7,8 | OUT | Parallel output power pins; share current path to reduce IR drop and thermal concentration. |
Key Features
| Feature | Design Value |
|---|---|
| Output Discharge Function | Integrated 250Ω discharge path automatically engages on disable, eliminating need for external FET/resistor network. |
| Reverse Current Blocking | Prevents backflow from OUT to IN when disabled, critical for multi-rail systems sharing common outputs. |
| No FLAG Glitch During Power-Up | Internal power-on reset ensures FLAG remains high until valid operation is established, avoiding spurious host interrupts. |
| Under-Voltage Lockout | UVLO threshold at 1.95V (rising) with 250mV hysteresis prevents erratic switching during input ramp-up or brownout. |
| Thermal-Shutdown Hysteresis | 20°C hysteresis (140°C trip / 120°C recovery) enables autonomous restart without external reset circuitry. |
Applications
| USB Power Distribution | PC Card Hot Swap |
|---|---|
|
Use Scenario: Providing controlled 5V power to USB peripherals with inrush limiting and short-circuit protection. IC Role / Device Role / Timing Role: Power switch managing VBUS delivery, with FLAG signaling faults to USB controller.

Use Value: Eliminates need for discrete MOSFET + comparator + RC timing networks, reducing BOM count by ≥4 components. |
| Notebook PC Power Rails | Telecom Line Card Protection |
|
Use Scenario: Distributing 3.3V/5V standby power to sub-systems like WWAN modules or audio codecs. IC Role / Device Role / Timing Role: Load switch with UVLO and thermal monitoring ensures rail stability during sleep/wake transitions. Use Value: 90μA quiescent current minimizes battery drain in S3/S4 suspend states; SOIC8 footprint simplifies layout near connectors. |
Use Scenario: Protecting downstream Ethernet PHYs or transceivers from field-induced surges or miswiring. IC Role / Device Role / Timing Role: First-line current limiter upstream of LDOs or DC-DC converters on line cards. Use Value: 2.8A current limit and 140°C thermal cutoff prevent cascading failures in dense telecom chassis with limited airflow. |
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 | Active-high EN, 1.2A continuous, no integrated discharge, 45mΩ RDS(on). | Lacks output discharge; requires external circuit for USB compliance; lower current rating limits use in 2A USB-C ports. | Select when higher efficiency at <1A loads is prioritized and discharge is handled externally. |
| ON Semi NIS5132MN | SOIC8, 2A continuous, no FLAG pin, no UVLO, 100mΩ RDS(on). | Missing fault reporting and input monitoring; unsuitable for systems requiring OCP diagnostics or brownout immunity. | Choose only for cost-sensitive, non-diagnostic applications where FLAG and UVLO are omitted from system architecture. |
Compared with TPS22965DRLR and NIS5132MN, MP62160DS-LF-Z uniquely combines SOIC8 packaging, active-low EN, integrated 250Ω discharge, and open-drain FLAG with deglitch-enabling full USB-compliant power control without supplemental components.

FAQ
What is the logic polarity of the EN pin on MP62160DS-LF-Z?
The EN pin on MP62160DS-LF-Z is active-low: the device enables when EN is pulled below 0.8V and disables when EN rises above 2V. This matches the "DS" suffix designation in the ordering table and differs from the MP62161 series, which uses active-high EN.
Does MP62160DS-LF-Z require an external pull-up on the FLAG pin?
Yes-FLAG is an open-drain output and requires an external pull-up resistor (typically 10kΩ to 5V or VCC) to generate a valid logic-high signal. The internal pull-up is absent; without external bias, FLAG remains floating and cannot assert a high state.
Can MP62160DS-LF-Z be used with 2.5V input voltage?
No-MP62160DS-LF-Z has a minimum input voltage of 2.7V per absolute maximum ratings and electrical characteristics tables. At 2.5V, UVLO will hold the device disabled, and RDS(on) performance degrades outside specified operating range.
How does the output discharge function behave during thermal shutdown?
The output discharge function remains active during thermal shutdown: if EN is low or UVLO is triggered, the 250Ω internal discharge path connects OUT to GND regardless of thermal state, ensuring rapid capacitor bleed-down even under fault conditions.
Is the SOIC8 package of MP62160DS-LF-Z lead-free and RoHS compliant?
Yes-the "-LF" suffix explicitly denotes lead-free and RoHS-compliant packaging. The device meets JEDEC J-STD-020 moisture sensitivity level 3 and is qualified for standard SnPb and lead-free reflow profiles.
What is the maximum recommended output capacitance for stable turn-on?
The datasheet specifies timing parameters (e.g., 3ms turn-on time) with CL = 100μF and RL = 5Ω. While larger capacitances (e.g., 470μF) are permissible, they increase inrush duration and may trigger OCP if not paired with sufficient current-limit margin or soft-start design.
Does MP62160DS-LF-Z support reverse current flow from OUT to IN?
No-it includes integrated reverse current blocking: when disabled or under UVLO, the internal MOSFET body diode is effectively blocked, preventing backfeed from loaded outputs into the input rail-a key requirement in multi-supply systems.
