BD6510F / BD6512F / BD6513F Multimedia ICs Low ON resistance USB high-side switch series BD6510F / BD6512F / BD6513F This series of high-side switching ICs have 2-channnel MOSFET switches that have low ON resistances. These functions are useful for USB power control. Error signals can be conveyed via a built-in error detection circuit. Also included is a thermal shutdown circuit with a latch that can protect the output from unstable operation occurred by repeating the ON/OFF switch of the output protection circuit. z Applications USB hub, Notebook PC, Desk-top PC, Power switch z Features 1) Dual DMOS Highside switches. 2) Control logic ActiveHigh (BD6510F / BD6512F) ActiveLow (BD6513F) High level input > 2.5V , Low level input < 0.7V 3) Low on resistance Typ. = 100m (VDD = 5V) 4) Continuous output load current Min. = 1A (BD6510F) Min. = 0.6A (BD6512F / BD6513F) 5) Soft start circuit 6) Error detection circuit, Output protection circuit (Over current detector, Thermal shutdown, Under voltage lockout.) 7) Opendrain Error Flag output. z Absolute maximum ratings (Ta=25C) Parameter Symbol Limits Unit Supply voltage VDD 0.3 to +6.0 V Terminal Input VIN 0.3 to VDD+0.3 V Storage Temperature TSTG 55 to +125 C Power dissipation Pd 450 mW This value decreases 4.5mW/C above 25C.
