MP5048GU-P

MP5048 60V, 15A, 7mΩ RDS(ON) Hot-Swap Intelli-Fuse Solution DESCRIPTION FEATURES The MP5048 is a monolithic, integrated controller and switch. It contains a high-side MOSFET and circuitry that enable it to operate as a standalone device, or to be controlled by a hot-swap controller. The MP5048 is capable of driving up to 15A of continuous current per MP5048 device.      The device limits the inrush current to the load when a circuit card is inserted into a live backplane power source. This limits the backplane’s voltage drop. The MP5048 also limits the internal MOSFET current by controlling the gate voltage through the current-limit reference input. The MP5048 offers many features to simplify the system design. It provides an integrated solution to monitor the output current and the die temperature, eliminating the need for an external current-sense power resistor, power MOSFET, or thermal sense. The MP5048 detects the power FET gate, source, and drain short conditions, and provides feedback for the controller. The device can be paralleled for higher current applications. The MP5048 is available in an QFN-30 (5mmx5mm) package.

The MP5048 operates from a 24V to 60V input rail. Output voltage controlled by the IC. VOUT is connected to the source of the integrated MOSFET. Current-sense output. CS requires an external resistor. The CS voltage (VCS) is compared to CLREF to determine the current limit. Current monitor output. The output current is proportional to the current flowing through the power device. Place a resistor (RIMON) to GND to set the output gain. Soft-start set. An external capacitor connected to SS sets the output voltage soft-start time. The internal circuit controls the slew rate of the output voltage during start-up. Fault indication. Open-drain output. FAULT indicates that a fault condition has occurred. Timer set. An external capacitor sets the insertion delay, over-current protection (OCP) delay time, and the retry time. Current-limit reference voltage input. The CLREF pin sets the voltage reference for the over-current prtotection (OCP) level. Connect a resistor to GND, or drive via an external source. Ground. Power FET on/off control. Drive the ON pin high to enable the MP5048. Internal 3V LDO output. Place a 2.2µF decoupling capacitor close to 3V and GND. Internal 4.5V LDO output. VCC can be driven with an external 4.5V to reduce loss from VIN. Place a 2.2µF decoupling capacitor close to VCC and GND. Junction temperature sense output. Output of the internal temperature sensor Latch or hiccup operation. When the MODE pin is pulled high, the part latches off if a fault occurs. It can be configured to latch-off mode by pulling the MODE pin up to 5V externally, or floating this pin since MODE is internally pulled up. When MODE is pulled low externally, the part operates in auto-retry mode. θJA θJC ABSOLUTE MAXIMUM RATINGS (1) Thermal Resistance (4) VIN(DC) ... .........................................-0.3V to +65V VIN(25ns) ......................................................... 72V VOUT............................................... -0.3V to +65V All other pins ............................... -0.3V to +6.5V Continuous power dissipation (TA = 25°C) (2) ………………………………………………. 5.58W Junction temperature ............................... 150°C Lead temperature .................................... 260°C Storage temperature ................ -65°C to +155°C QFN-30 (5mmx5mm)...………22.4……9.6..°C/W Recommended Operating Conditions (3) Input voltage operating range .......... 24V to 60V Operating junction temp (TJ) .... -40°C to +125°C MP5048 Rev. 1.1 4/30/2021 Notes: 1) Exceeding these ratings may damage the MP5048. 2) The maximum allowable power dissipation is a function of the maximum junction temperature, TJ (MAX), the junction-toambient thermal resistance, θJA, and the ambient temperature, TA. The maximum allowable continuous power dissipation at any ambient temperature is calculated by PD (MAX) = (TJ (MAX) - TA) / θJA. Exceeding the maximum allowable power dissipation produces an excessive die temperature, causing the regulator to go into thermal shutdown. Internal thermal shutdown circuitry protects the MP5048 from permanent damage. 3) The MP5048 is not guaranteed to function outside of its operating conditions. 4) Measured on JESD51-7, 4-layer PCB. www.MonolithicPower.com MPS Proprietary Information.
