The IMP2525 conforms to USB standards with a low output switch ON-resistance (RON) and minimal voltage drop across the switch. The fault current is limited to 750mA typically, and a flag output conveys fault conditions to the local USB controller. The IMP2525 provides a “Soft-Start” function that ramps up the ON- current to eliminate any excessive voltage drop on the input side that could occur due to charging a capacitive load in bus-powered applica- tions. Self-monitoring features include thermal shutdown to prevent catastrophic switch failure from high-current loads and undervoltage lockout (UVLO) that insures that the device remains off unless there is a valid supply voltage present. The Enable input logic can be interfaced with both 3.3V and 5V logic. Both active-HIGH and active-LOW enable logic versions are available. The IMP2525 devices are available in 8-pin DIP and 8-pin SO packages. IMP offers a complete family of USB power management products. For dual-switch applications see the IMP2526 data sheet and for quad-switch application, see the IMP2524. The single-switch IMP2525A features a 50% lower switch resistance, 0.07 Ω. 2525_01.eps OUT NC/OUT 8 6 FLG 2 GND 3 IMP2525 Power Switch Gate Control Current Limit 1.2V Reference UVLO Thermal Shutdown Oscillator EN 1 IN 7 Charge Pump Key Features |
