MP5021B
12 V, 7 mΩ RDSon Hot-Swap Protection Device with Current Monitoring

The MP5021B is a hot-swap protection device designed to
• V to 16 V Operating Input Range
protect circuitry on its output from transients on its input. Also,
• Integrated 7 mΩ Power FET
it protects its input from undesired shorts and transients
• Adjustable Current Limit
coming from its output.
• Output Current Measurement

At start-up, the slew rate at the output limits the inrush
• ±5% Current Monitor Accuracy
current. An external capacitor at SS controls the slew rate.
• Fast Response <200 ns for Short Protection

The maximum output load is current limited using a sense
• PG Detector and FLTB Indication

FET topology where a low-power resistor from ISET to ground
• PG Assert Low at VIN = 0
controls the magnitude of the current limit.
• Damaged MOSFET Detection

An internal charge pump drives the gate of the power device,
• External Soft-Start
allowing a power FET with a very low on resistance of 7
• Programmable EN Blanking Time

The MP5021B includes an IMON option to produce a voltage
• Under/Over-Voltage Lockout
proportional to the current through the power device, as set by
• Thermal Protection
a resistor from IMON to ground.
• Small QFN-22 3mmx5mm Package

The MP5021B includes an optional discharge function that
provides a discharge path for the external output capacitor when the part is disabled. Fault protections include currentlimit protection, thermal shutdown, and damaged MOSFET detection. Both the current limit and thermal shutdown have user-settable auto-retry and latch-off mode. Also, the device features over-voltage protection OVP and under-voltage
