Product details
Overview
MP6212DH-LF-Z from Monolithic Power Systems is an active-low, single-channel 1A current-limited power distribution switch with 90mΩ RDS(on), 2.7V–5.5V input range, and thermal shutdown protection. It delivers precise current limiting (1.1–2.2A trip range), reverse current blocking, and 8ms FLAG deglitching for USB VBUS switching in portable electronics.
For engineers reviewing the MP6212DH-LF-Z datasheet, MP6212DH-LF-Z pinout, MP6212DH-LF-Z application, or MP6212DH-LF-Z equivalent, key selection criteria include enable polarity (active-low), SOIC8E exposed-pad thermal performance, UVLO threshold (1.95–2.65V), and open-drain FLAG response timing under short-circuit conditions.
Technical Context
The MP6212DH-LF-Z integrates a low-RDS(on) N-channel MOSFET with internal current-sense amplifier, thermal sensor, and deglitched open-drain FLAG output. Its constant-current limiting activates at ≥1.7A (typical trip) and transitions to thermal shutdown above 140°C junction temperature.
It features under-voltage lockout (UVLO) with 250mV hysteresis, 90μA quiescent current during operation, and no FLAG glitch during power-up. The device supports reverse current blocking and operates across –40°C to +85°C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 1.0A - Sustained load capability without derating at TA ≤ +70°C with proper PCB copper area. |
| Current Limit Range | 1.1–2.2A - Guaranteed trip threshold ensures robust fault handling across voltage/temperature variation. |
| RDS(on) | 90mΩ (typ) - Minimizes conduction loss (≤55mW at 1A), critical for thermally constrained USB ports. |
| Supply Voltage Range | 2.7V–5.5V - Supports direct integration into 3.3V and 5V rail systems including USB 2.0/3.0 VBUS. |
| FLAG Deglitch Time | 4–15ms - Eliminates false overcurrent reporting from transient inrush or ESD events. |
| Thermal Shutdown | 140°C (typ) - Protects die integrity during sustained overload; 20°C hysteresis enables automatic recovery. |
| UVLO Threshold | 1.95–2.65V - Prevents erratic switching during brown-out; 250mV hysteresis avoids oscillation near threshold. |
Pinout & Package
MP6212DH-LF-Z uses an 8-pin SOIC package with exposed thermal pad (SOIC8E), requiring solder connection of the pad to PCB ground plane for θJA = 50°C/W and optimal thermal dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND (exposed pad) | Primary thermal and electrical reference; must be connected to large copper pour for heat sinking. |
| 2,3 | IN | Input power rail (2.7–5.5V); accepts USB VBUS, battery, or regulated DC supply. |
| 4 | EN | Active-low enable: pulls low to activate switch; compatible with CMOS/TTL logic levels. |
| 5 | FLAG | Open-drain fault indicator: pulled low after 8ms deglitch on overcurrent or thermal shutdown. |
| 6,7 | OUT | Switched output to load; includes reverse current blocking when IN = GND and OUT = VLOAD. |
| 8 | NC | No internal connection; left unconnected per datasheet; not used for routing or grounding. |
Key Features
| Feature | Design Value |
|---|---|
| Accurate current limit | 1.1–2.2A trip range ensures predictable fault behavior without external sensing components. |
| Reverse current blocking | Prevents backflow from powered loads (e.g., USB peripherals) into host supply during disable or fault. |
| No FLAG glitch at power-up | Eliminates need for external RC filtering on FLAG line, simplifying BOM and layout. |
| Under-voltage lockout | Guarantees clean turn-on only above 1.95V, preventing unstable operation during supply ramp-up. |
| SOIC8E thermal pad | Enables 2.5W continuous power dissipation at +25°C ambient-critical for compact USB hub designs. |
Applications
| USB 2.0/3.0 Port Switching | Smartphone Peripheral Power Control |
|---|---|
|
Use Scenario: Isolating VBUS power to individual USB downstream ports in multi-port hubs or docking stations. IC Role / Device Role / Timing Role: Single-channel power switch enabling/disabling 5V delivery with current limiting and fault reporting. Use Value: Prevents bus-wide shutdown during cable short; FLAG signal triggers host firmware recovery within 8–15ms. |
Use Scenario: Controlling power to SD card slots, OTG accessories, or USB-C alternate mode peripherals in smartphones. IC Role / Device Role / Timing Role: Load switch with reverse current blocking and thermal protection for battery-sensitive applications. Use Value: Blocks backfeed from accessory into phone battery; 90μA quiescent current minimizes standby drain. |
| Notebook PC ExpressCard/USB Expansion | Set-Top Box HDMI/USB Power Management |
|
Use Scenario: Managing hot-plug power to ExpressCard or USB 3.0 expansion modules in ultrabooks. IC Role / Device Role / Timing Role: Active-low controlled distribution switch with UVLO and fast turn-off (<10ms). Use Value: Ensures safe insertion/removal by disabling output before EN deassertion; prevents inrush-induced system reset. |
Use Scenario: Enabling/disabling 5V power to HDMI CEC circuitry or USB service ports in consumer STBs. IC Role / Device Role / Timing Role: Fault-tolerant power gate with thermal shutdown and open-drain FLAG for MCU monitoring.

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 TPS2051BDBVR | Active-high enable, 1.5A fixed current limit, no reverse current blocking, SO-8 package without exposed pad. | Lacks thermal shutdown hysteresis and reverse blocking; requires external UVLO for brown-out immunity. | Select when active-high control aligns with existing logic and thermal margin is sufficient without exposed pad. |
| ON Semi NCP380LSN3T2G | Active-low enable, 3A current limit, 120mΩ RDS(on), no FLAG deglitch, TSOP-6 package. | Higher current rating but larger on-resistance increases conduction loss; no deglitching risks false FLAG asserts. | Choose for higher current needs where FLAG reliability is managed externally via MCU firmware debouncing. |
Compared with TPS2051BDBVR and NCP380LSN3T2G, MP6212DH-LF-Z provides tighter current-limit accuracy, integrated reverse blocking, and guaranteed 8ms FLAG deglitch-reducing firmware complexity and PCB area in space-constrained USB applications.

FAQ
What is the exact enable polarity of MP6212DH-LF-Z?
The MP6212DH-LF-Z has active-low enable (EN pin): the internal MOSFET turns ON when EN is pulled low (≤0.8V) and turns OFF when EN is high (≥2V). This matches the "DN" suffix designation in the MP6212 family and differs from the MP6211's active-high configuration.
Does MP6212DH-LF-Z support reverse current blocking, and how is it implemented?
Yes-it blocks reverse current flow from OUT to IN when IN is grounded and OUT is biased (e.g., by a powered peripheral). This is achieved via internal body-diode orientation and gate control logic, eliminating the need for an external Schottky diode in USB OTG or dual-power-source configurations.
What is the maximum continuous power dissipation for MP6212DH-LF-Z at +70°C ambient?
At +70°C ambient, maximum continuous power dissipation is 1.6W, calculated using PD(MAX) = (TJ(MAX) − TA)/θJA = (150°C − 70°C)/50°C/W. This assumes SOIC8E mounted on a 4-layer PCB with full thermal pad soldering per JEDEC MS-012 BA standard.
How does the FLAG pin behave during thermal shutdown versus overcurrent events?
FLAG goes low after 8ms deglitch timeout for both overcurrent and thermal shutdown. However, during UVLO or initial power-up, FLAG remains high (undriven) with no deglitch applied-ensuring no false assertion before stable operation begins.
Is the NC pin (Pin 8) required to be grounded or left floating?
Pin 8 is internally unconnected (NC) and must remain unconnected on the PCB. Neither grounding nor routing is permitted; doing so may compromise package integrity or cause unintended coupling per MPS package documentation.
What input capacitance is recommended between IN and GND?
A minimum 10μF ceramic or tantalum capacitor is recommended between IN and GND to suppress input transients and improve immunity to short-circuit ringing. This value is validated in the datasheet's power-supply considerations section and supports stable operation under USB VBUS surge conditions.
Can MP6212DH-LF-Z be used in automotive infotainment USB ports?
No-MP6212DH-LF-Z is rated for –40°C to +85°C ambient and lacks AEC-Q100 qualification, automotive-grade ESD tolerance (e.g., ±15kV HBM), or extended temperature validation. It is intended for commercial portable and computing applications only.
