MX5052S Datasheet | MAXINMICRO

description The MX5052S high-side OR-ing works with an internal MOSFET and acts as an ideal diode rectifier when connected in series with the power supply. This OR-ing circuit enables MOSFETs to replace diode rectifiers in power distribution networks, reducing power loss and voltage drop. The MX5052S controller provides charge pump gate drive for an internal N-channel MOSFET and fast response parator to turn off the FET when current flows in reverse. The MX5052S can be connected to power supplies from 1V to 40V （a separate VS supply is needed when IN is 1V to 4V）and can withstand transient voltages up to 60V. Features - Wide operating input voltage range VIN: 5V to 40V - 60V transient voltage - Charge pump gate driver for internal N-channel MOSFET - 50ns fast response to current reversal - 2A peak gate off current internal - Ultra-small VDS turn-off voltage reduces turn-off time - 8-Pin SOP8L Applications Typical application +5V ~ +40V MX5052S VS MX5052S 3A High-Side OR-ing FET Circuit Active OR-ing of redundant (N+1) power supplies General information Ordering information Part Number MX5052S MPQ Description SOP8L 3000pcs Package dissipation rating Package SOP8L RθJA（℃/W） 108.1 Absolute maximum ratings Parameter IN, OUT Pins to GND VS Pin to Ground Internal MOSFET VDS Value -0.3 to 50V -0.3 to 50V ≥60V Junction temperature Storage temperature, Tstg Leading temperature （soldering,10secs） ESD Susceptibility HBM 150℃ -50 to 150℃ 260℃ ±2000V Stresses beyond those listed in Absolute Maximum Ratings may cause permanent damage to the device.
