Product details
Overview
MP6211DN-LF-P from Monolithic Power Systems is a single-channel, active-high enable, current-limited power distribution switch with 1A continuous load capability, 90mΩ RDS(ON), and 2.7V–5.5V input range. It integrates thermal shutdown, under-voltage lockout, reverse current blocking, and an open-drain FLAG output for overcurrent detection-used in USB power distribution and portable device load switching.
For engineers reviewing the MP6211DN-LF-P datasheet, MP6211DN-LF-P pinout, MP6211DN-LF-P application, or MP6211DN-LF-P equivalent, key selection criteria include guaranteed 1.5A short-circuit trip current, 8ms FLAG deglitch time, SOIC8E exposed-pad thermal performance, and active-high EN logic compatibility with USB VBUS control architectures.
Technical Context
The MP6211DN-LF-P implements a precision current-limit architecture using internal sense-FET feedback and a charge-pump gate driver to maintain constant-current mode at ≥1.5A during overload. Its UVLO (1.95V–2.65V) ensures clean startup only above minimum supply threshold.
Thermal protection triggers at 140°C with 20°C hysteresis, forcing output disable until junction cools to ~120°C; the FLAG pin asserts low after 8ms deglitch delay only for sustained overcurrent-not during UVLO or transient inrush.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Load Current | 1.0A - Sustained output current without derating at TA ≤ +85°C with proper PCB copper pour. |
| Current Limit Threshold | 1.5A (typ) - Trip point initiating constant-current mode; protects downstream loads from >1.5A faults. |
| RDS(ON) | 90mΩ (typ) - Low conduction loss enabling <45mW dissipation at 1A, critical for thermally constrained USB ports. |
| Supply Voltage Range | 2.7V–5.5V - Supports direct connection to 3.3V logic rails and 5V USB VBUS without external regulators. |
| FLAG Deglitch Time | 8ms - Prevents false fault reporting during capacitive inrush or brief transients; eliminates need for external RC filters. |
| Quiescent Current | 90μA - Enables ultra-low standby power in battery-powered systems when EN is deasserted. |
| Thermal Shutdown Temp | 140°C - Die temperature threshold triggering automatic output disable to prevent permanent silicon damage. |
Pinout & Package
MP6211DN-LF-P is housed in an 8-pin SOIC package with exposed thermal pad (SOIC8E), requiring solder connection of the pad to a GND plane for θJA = 50°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (Exposed Pad) | Primary thermal and electrical ground reference; must be connected to PCB GND plane for thermal integrity. |
| 2,3 | IN | Power input node accepting 2.7V–5.5V; connects directly to source rail (e.g., USB VBUS or 3.3V SMPS output). |
| 4 | EN | Active-high enable input; drives internal FET gate when ≥2V; compatible with 3.3V/5V logic levels. |
| 5 | FLAG | Open-drain fault indicator; pulls low after 8ms deglitch on sustained overcurrent; requires external pull-up. |
| 6,7 | OUT | Switched power output; delivers regulated current to load; supports reverse current blocking when IN = 0V. |
| 8 | NC | No internal connection; left unconnected per design; no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| Accurate 1.5A current limit | Guaranteed trip threshold enables predictable fault response without external sensing resistors or controllers. |
| 8ms FLAG deglitch | Hardware-based filtering eliminates false interrupts during hot-plug events or bulk capacitor charging. |
| Reverse current blocking | Prevents backflow from OUT to IN when input is disabled or absent-critical for multi-rail USB host designs. |
| Under-voltage lockout (UVLO) | 1.95V rising-edge threshold prevents erratic switching during brown-out or soft-start conditions. |
| Thermal shutdown with hysteresis | 140°C trip / 120°C recovery ensures safe cooldown before re-enabling, avoiding thermal cycling stress. |
Applications
| USB Power Delivery Switching | Smartphone Peripheral Power Control |
|---|---|
Use Scenario: Managing power to USB Type-A ports in docking stations where individual port current limiting is required. IC Role / Device Role / Timing Role: Single-channel load switch enforcing 1.5A trip limit and reporting faults via FLAG to host MCU.

Use Value: Maintains consistent load-switch behavior across full battery discharge curve without external LDO intervention. |
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 | 1.5A limit, 44mΩ RDS(ON), 0.5μA quiescent current, no thermal shutdown, no FLAG output. | Lacks fault reporting and thermal protection; suited for benign environments where only current limiting is needed. | Select when lowest on-resistance and ultra-low IQ are prioritized over fault diagnostics and thermal safety. |
| ON Semi NCP45520MUTBG | 2.5A limit, 22mΩ RDS(ON), 120μA IQ, includes FLAG but no UVLO, thermal shutdown at 150°C. | Higher current rating and lower RDS(ON) but lacks under-voltage lockout-requires external supervision for brown-out immunity. | Select for high-current, low-loss applications where UVLO is managed externally and thermal margin is sufficient. |
Compared with TPS22965DRLR and NCP45520MUTBG, MP6211DN-LF-P uniquely combines integrated FLAG reporting, UVLO, thermal hysteresis, and SOIC8E thermal performance in a 1A-class switch-making it optimal for USB-compliant, fault-aware portable designs.

FAQ
What is the maximum allowable input voltage for MP6211DN-LF-P?
The absolute maximum input voltage (IN) is +6.0V, but the recommended operating range is 2.7V to 5.5V. Exceeding 6.0V risks permanent damage to the internal MOSFET and protection circuitry, as specified in the Absolute Maximum Ratings table.
Does MP6211DN-LF-P support reverse current blocking when disabled?
Yes. When the device is disabled (EN low), the internal MOSFET blocks reverse current flow from OUT to IN, with measured reverse leakage of ≤0.2μA at OUT = 5.5V and IN = 0V-enabling safe isolation of downstream loads.
How does the FLAG pin behave during thermal shutdown?
The FLAG pin is not deglitched during thermal shutdown; it asserts immediately upon junction temperature reaching 140°C. Unlike overcurrent events, thermal faults bypass the 8ms deglitch timer to provide fastest possible fault indication.
Can MP6211DN-LF-P drive a 100μF output capacitor without instability?
Yes. The datasheet specifies turn-on time (Ton) and turn-off time (Toff) test conditions with CL = 100μF and RL = 5.5Ω, confirming stable operation. A 10μF minimum input capacitor is recommended to suppress supply transients.
Is the exposed pad electrically connected internally?
No. The exposed pad is connected solely to the internal GND plane for thermal conduction and must be soldered to a PCB GND copper area. It is not electrically isolated and carries no signal or voltage other than GND potential.
What is the typical RDS(ON) variation over temperature?
RDS(ON) increases from 90mΩ at +25°C to ~130mΩ at +85°C (per Electrical Characteristics table), resulting in ~45% higher conduction loss at max ambient-requiring thermal design margin for 1A continuous operation.
Does MP6211DN-LF-P require external components for basic operation?
No. Basic operation only requires input/output capacitors (≥10μF on IN, optional on OUT) and a pull-up resistor on FLAG if used. No external current-sense resistors, comparators, or thermal sensors are needed due to full integration.
