Product details
Overview
EV5022C-QV-00A from Monolithic Power Systems is a hot-swap protection device integrating a 3mΩ RDS(ON) N-channel MOSFET, supporting 12V input/output operation with 15A continuous load current and ±3% current limit/monitor accuracy. It provides fast short-circuit response (<200ns), programmable EN blanking time, and dual over/under-voltage lockout for server backplane and PC card power rail protection.
For engineers reviewing the EV5022C-QV-00A datasheet, EV5022C-QV-00A pinout, EV5022C-QV-00A application, or EV5022C-QV-00A equivalent, key selection criteria include adjustable current limit threshold, PG/FLTB fault signaling, IMON analog current monitoring output, thermal shutdown behavior, and QFN22 (3mm×5mm) package thermal performance in high-density hot-swap implementations.
Technical Context
The EV5022C-QV-00A implements a charge-pump–driven gate controller for low-RDS(ON) FET operation across 4.5V–16V input range. Its internal current-sense amplifier delivers IMON output proportional to load current with ±3% gain error, while the FLTB pin asserts open-drain low on overcurrent, thermal fault, or damaged-MOSFET detection.
PG (Power Good) asserts low when VIN drops below UVLO threshold and remains asserted only after soft-start completion and stable output regulation. The device supports external soft-start via SS pin and enables EN-controlled sequencing with user-defined blanking time to suppress false turn-on during input transients.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5V to 16V - Supports 12V server rails and accommodates input ripple without UV/OV lockout activation |
| RDS(ON) | 3mΩ max - Enables <180mW conduction loss at 15A, reducing thermal stress in compact QFN22 layout |
| Continuous Output Current | 15A - Rated for sustained load in hot-swap insertion events with thermal shutdown protection |
| Current Limit Accuracy | ±3% - Ensures precise fault threshold setting for system-level current budgeting and fuse coordination |
| Short-Circuit Response Time | <200ns - Limits energy delivery during output shorts to protect downstream capacitors and traces |
| IMON Accuracy | ±3% - Provides reliable real-time load current telemetry for system health monitoring and dynamic power management |
| Soft-Start Control | External SS pin - Allows user-defined ramp rate to control inrush current into large output capacitance banks |
Pinout & Package
EV5022C-QV-00A is housed in a thermally enhanced 22-pin QFN package (3mm × 5mm, 0.5mm pitch) with exposed thermal pad. Pin numbering follows standard QFN convention, with power pins grouped on two sides for low-inductance layout.

| VOUT | Output Power Rail | Switched output node; connects to protected load and external bulk capacitor |
| EN | Enable Input | Active-high logic input; includes programmable blanking time to reject noise during power-up |
| PG | Power Good Output | Open-drain signal asserting low when VIN is valid and output has completed soft-start |
| FLTB | Fault Indicator | Open-drain output pulled low on overcurrent, thermal shutdown, or MOSFET failure detection |
| IMON | Analog Current Monitor | Voltage output proportional to load current (100mV/A typical); used for telemetry and closed-loop control |
| SS | Soft-Start Timing | Connects external capacitor to set output voltage ramp rate and inrush current profile |
| ISET | Current Limit Set | Resistor-to-ground sets overcurrent threshold; supports 10A–20A adjustment range |

FAQ
What is the function of the IMON pin on EV5022C-QV-00A?
The IMON pin provides an analog voltage output proportional to load current (typically 100mV/A) with ±3% accuracy. It connects directly to an ADC input for real-time current telemetry, enabling system-level power budgeting, predictive maintenance, and dynamic load balancing without external sense resistors.
How does the damaged MOSFET detection work?
The device continuously monitors gate-to-source voltage during conduction. If VGS falls below a threshold indicating gate oxide failure or bond wire lift-off, FLTB asserts and internal current limiting engages. This prevents uncontrolled short-circuit current through a degraded FET channel.
Can EV5022C-QV-00A operate at 5V input?
No. The minimum operating input voltage is 4.5V, but the internal charge pump requires sufficient headroom to drive the 3mΩ FET gate fully. At 5V input, RDS(ON) increases significantly, causing excessive conduction loss and potential thermal shutdown under 15A load.
What is the purpose of the EN blanking time feature?
The EN blanking time delays enablement for a user-programmable duration after EN rises above 2V. This prevents false triggering from power supply turn-on transients or noise coupling, ensuring the device only activates once input voltage stabilizes within UVLO window.
Is the EV5022C-QV-00A RoHS compliant and lead-free?
Yes. EV5022C-QV-00A meets RoHS Directive 2011/65/EU requirements and is manufactured with lead-free, halogen-free materials. Full compliance documentation, including substance declarations and test reports, is available on the MPS Quality Assurance portal.
How is overvoltage protection triggered?
OVP activates when VIN exceeds 16.5V (typical), forcing immediate shutdown and pulling FLTB low. The threshold is internally trimmed and temperature-compensated; recovery requires cycling EN or power cycling after the overvoltage condition clears.
Does the evaluation board support adjustable current limit?
Yes. The EV5022C-QV-00A evaluation board includes R13 (NS placeholder) and routing for an ISET resistor between ISET pin and GND. Populating this resistor allows users to set current limit thresholds from 10A to 20A per the MP5022C datasheet's ILIM vs. RISET curve.
