PowerManagementSwitchICSeriesforPCsandDigitalConsumerProduct Large Current Output Power Management Switch ICs BD6520F,BD6522F Description The power switch for expansion module is a power management switch having one circuit of N-channel Power MOS FET. The switch realizes 50mΩ(Typ.) ON resistance. The switch turns on smoothly by the built-in charge pump, therefore, it is possible to reduce inrush current at switch on. And soft start control by external capacitor is available. Further, it has a discharge circuit that discharges electric charge from capacitive load at switch off, Under voltage lockout circuit, and a thermal shutdown circuit. Features 1) Low on resistance (50mΩ, Typ.) N-MOS switch built in 2) Maximum output current: 2A 3) Discharge circuit built in 4) Soft start control circuit built in 5) Under voltage lockout (UVLO) circuit built in 6) Thermal shutdown (Output off latching) 7) Reverse current flow blocking at switch off (only BD6522F) Applications Notebook PC, PC peripheral device, etc. Lineup Parameter BD6520F BD6522F Supply Voltage 3 to 5.5V 3 to 5.5V Switch current 2A 2A On Resistance 50mΩ 50mΩ OUT Rise Time 2000us 1000us OUT Fall Time 3us 4us Package SOP8 SOP8 Reverse current flow blocking at switch off - ○ Absolute Maximum Ratings Parameter Symbol Rating Unit Supply Voltage VDD -0.3 to 6.0 V CTRL Input Voltage VCTRL -0.3 to 6.0 V Switch Output Voltage VOUT -0.3 to VDD + 0.3 (BD6520F) V -0.3 to 6.0 (BD6522F) V Storage temperature TSTG -55 to 150 ℃ Power dissipation Pd 560 *1 mW *1 This value decreases 4.48mW/℃ above Ta=25℃ * Resistance radiation design is not doing. * Operation is not guaranteed.
