FPF1203UCX

IntelliMAX™ Ultra-Small, Slew-Rate-Controlled Load Switch Features         Description 1.2 V to 5.5 V Input Voltage Operating Range The FPF1203 / 03L / 04 / 45 are ultra-s mall integrated IntelliMA X™ load sw itches w ith integr ated P-channel sw itch and analog control features. Integrated s lew rate control pr events inr ush current and the resulting excessive voltage drop on the pow er rail. The input voltage range operates from 1.2 V to 5.5 V to provide pow er-disconnect capability for post-regulated pow er rails in por table and cons umer pr oducts. The low shutoff current allow s pow er designs to meet standby and off-pow er drain specifications. Typical RON:   45 mΩ at V IN=5.5 V 55 mΩ at V IN=3.3 V  90 mΩ at V IN=1.8 V  185 mΩ at V IN=1.2 V Slew Rate Control w ith tR:  FPF1203/FPF1203l/ FPF1204:  FPF12045: 100 µs The FPF120x are c ontr olled by a logic input ( ON pin) compatible w ith standar d CMOS GPIO circuitry found on Field Programmable Gate Array (FPGA) embedded processors. The FPF120x are available in 0.76 mm x 0.76 mm 4-bump WLCSP. 2 µs Output Discharge Function on FPF1204 / 45 Low
