Product details

Overview

MP6215DH-LF-Z from Monolithic Power Systems is a single-channel, active-high enable, current-limited power distribution switch with 90mΩ internal MOSFET, 1.5A continuous load capability, and 2.3A typical current limit. It operates from 2.7V to 5.5V input, integrates thermal shutdown, under-voltage lockout, reverse current blocking, and open-drain FLAG for fault reporting-used in USB power distribution and PC Card hot-swap circuits.

For engineers reviewing the MP6215DH-LF-Z datasheet, MP6215DH-LF-Z pinout, MP6215DH-LF-Z application, or MP6215DH-LF-Z equivalent, key selection criteria include accurate 2.3A current-limit threshold, 8ms FLAG deglitch timing, MSOP8-EP thermal performance (θJA = 55°C/W), and active-high EN logic compatibility with 3.3V/5V host controllers.

Technical Context

The MP6215DH-LF-Z implements a precision current-sense amplifier and charge-pump gate driver to maintain constant-current regulation during overload, with trip threshold tightly controlled across temperature and input voltage. Its UVLO (2.65V rising edge) and thermal shutdown (140°C) operate independently of EN state to ensure fail-safe behavior before device enable.

FLAG output uses an internal 8ms deglitch timer to suppress transient overcurrent events but bypasses deglitching during thermal or UVLO faults-enabling immediate system-level response to critical conditions. Reverse current blocking prevents backfeed when IN is unpowered while OUT remains biased.

Key Specifications

Parameter	Value and Actual Design Meaning
Continuous Load Current	1.5A - Sustained output without thermal derating at TA ≤ +85°C on 4-layer PCB
Current Limit Threshold	2.3A (typ) - Enters constant-current mode at this level to protect downstream circuitry
R_DS(on)	85mΩ (at I_OUT = 100mA) - Limits conduction loss and self-heating under full load
Supply Current (EN = High)	140µA - Enables low-quiescent-power operation in always-on USB hub applications
FLAG Deglitch Time	8ms - Rejects short-duration overloads (<8ms) to avoid false fault assertions
Thermal Shutdown Temp	140°C - Triggers automatic disable; recovery occurs at ~120°C due to 20°C hysteresis
Input Voltage Range	2.7V to 5.5V - Supports both 3.3V and 5V USB VBUS rails without external regulators

Pinout & Package

MP6215DH-LF-Z is housed in an MSOP-8 package with exposed thermal pad (MSOP8E), optimized for thermal dissipation in space-constrained USB and notebook applications. The exposed pad must be soldered to PCB ground plane for θJA = 55°C/W performance.

Pin/Terminal	Circuit Role	Design Meaning
1 GND	Power and signal reference ground	Common return path for IN, OUT, EN, FLAG; connects to exposed pad for thermal conduction
2,3 IN	Input power supply terminal	Accepts 2.7–5.5V source; dual-pin layout reduces trace resistance and IR drop
4 EN	Active-high enable control input	Logic HIGH ≥2V enables switch; LOW ≤0.4V disables with 1µA shutdown current
5 FLAG	Open-drain fault indicator output	Asserts LOW after 8ms deglitched overcurrent or thermal/UVLO event; requires external pull-up
6,7,8 OUT	Power-distribution output terminals	Three parallel pins deliver up to 1.5A total; reduce current density and bond-wire stress

Key Features

Feature	Design Value
Accurate current limiting	2.3A typical trip threshold with <±15% variation over temperature and VIN ensures predictable fault response
No FLAG glitch during power-up	Internal sequencing prevents false fault assertion at startup, eliminating need for external reset coordination
Reverse current blocking	0.2µA max reverse leakage at OUT=5.5V/IN=GND prevents backfeed into disabled upstream rails
Under-voltage lockout	2.65V rising-edge UVLO with 250mV hysteresis avoids erratic switching near minimum operating voltage

Applications

USB Power Distribution

PC Card Hot Swap

Use Scenario: Providing individually switched 5V power to multiple USB ports on a laptop docking station.

IC Role / Device Role / Timing Role: Single-channel power switch with current limiting and FLAG fault reporting for per-port protection.

Use Value: Prevents bus-wide shutdown during single-port short; 8ms deglitch avoids nuisance interrupts from plug-in transients.

Use Scenario: Enabling safe insertion/removal of PCMCIA cards in industrial data acquisition systems.

IC Role / Device Role / Timing Role: Controlled power ramp-up with UVLO and thermal shutdown to prevent card damage during hot insertion.

Use Value: Ensures clean power sequencing and eliminates inrush-induced voltage droop on shared 3.3V/5V rails.

Notebook PC Power Management

Set-Top Box Peripheral Control

Use Scenario: Isolating auxiliary 3.3V supplies for SD card readers and Bluetooth modules in ultrabooks.

IC Role / Device Role / Timing Role: Low-quiescent (140µA) enable-controlled switch with reverse current blocking.

Use Value: Eliminates standby power loss from backfeed; supports instant-on resume by maintaining rail integrity.

Use Scenario: Managing 5V power to HDMI CEC receivers and IR blaster circuits in consumer STBs.

IC Role / Device Role / Timing Role: Fault-tolerant distribution switch with thermal protection for intermittent high-current loads.

Use Value: Survives repeated 2.3A surge events during IR burst transmission without latch-off.

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	1.5A continuous, 2.2A current limit, 120mΩ R_DS(on), no FLAG output	Lacks fault reporting; requires external comparator for OCP indication	Select when FLAG functionality is unnecessary and board space permits higher R_DS(on) loss
ON Semi NCP45520MUTBG	2.5A continuous, 3.5A current limit, 32mΩ R_DS(on), integrated soft-start	Higher current rating and lower on-resistance; no UVLO or reverse blocking	Prefer for high-current, low-loss designs where reverse feed risk is mitigated externally

Compared with TPS2051BDBVR and NCP45520MUTBG, MP6215DH-LF-Z uniquely combines FLAG-based fault signaling, reverse current blocking, and tight 2.3A current limit in MSOP8-EP-making it optimal for compact, fault-aware USB and hot-swap systems requiring minimal external components.

FAQ

What is the maximum allowable input voltage for MP6215DH-LF-Z?

The absolute maximum input voltage (IN) is +6.5V, but the recommended operating range is 2.7V to 5.5V. Operation above 5.5V risks permanent damage even for brief transients, and the UVLO circuit does not protect against overvoltage-external clamping is required if input surges exceed 5.5V.

Does MP6215DH-LF-Z support bidirectional current flow?

No. MP6215DH-LF-Z provides unidirectional IN-to-OUT power flow with integrated reverse current blocking. When IN is unpowered and OUT is biased (e.g., from a charged capacitor), reverse leakage is limited to 0.2µA max-preventing backfeed into upstream sources.

How does the FLAG pin behave during thermal shutdown versus overcurrent events?

FLAG asserts LOW after 8ms deglitch only for overcurrent events. During thermal shutdown or UVLO, FLAG activates immediately-without deglitch delay-to signal critical failures requiring urgent system intervention.

Can MP6215DH-LF-Z drive capacitive loads up to 100µF without instability?

Yes. The datasheet specifies 10ms turn-off time and 3ms turn-on time with CL = 100µF and RL = 5Ω. The internal gate driver and current-limit architecture ensure stable soft-start and controlled discharge, eliminating need for external slew-rate control.

Is the exposed pad on the MSOP8E package electrically connected internally?

Yes-the exposed pad is internally tied to GND and must be soldered to a PCB thermal pad connected to the system ground plane. This connection is essential to achieve the specified θJA = 55°C/W and prevent thermal shutdown under 1.5A continuous load.

What happens if the EN pin is left floating?

EN has no internal pull-up or pull-down. A floating EN results in undefined operation-potentially enabling or disabling unpredictably due to noise coupling. Design requires explicit biasing: tie to IN via 100kΩ resistor for default-enable, or to GND for default-disable.
