ures - 1 Integrated Single Load Switch - Four Pin Wafer-Chip-Scale Package (Nom) - 0.9 mm × 0.9 mm, 0.5-mm Pitch, 0.5-mm Height (YZV) - Input Voltage Range: 1.4 V to 5.5 V - Low ON-Resistance - r ON = 60 mΩ at VIN = 5 V - r ON = 61 mΩ at VIN = 3.3 V - r ON = 74 mΩ at VIN = 1.8 V - r ON = 84 mΩ at VIN = 1.5 V - 2-A Maximum Continuous Switch Current - Low Threshold Control Input - Controlled Slew-rate - Under-Voltage Lock Out - Full-Time Reverse Current Protection - Quick Output Discharge Transistor (TPS22913B/C Devices) 2 Applications - Notebook puter and Ultrabook™ - Tablets and Set-Top-Boxes - Portable Industrial / Medical Equipment - Portable Media Players - Point Of Sale Pins - GPS Navigation Devices - Digital Cameras - Portable Instrumentation - Smartphones / Wireless Handsets 3 Description The TPS22910A, TPS22912C, and TPS22913B/C are small, low r ON load switches with controlled turn on. The device contains a P-channel MOSFET that can operate over an input voltage range of 1.4 V to 5.5 V. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with lowvoltage GPIO control signals. The TPS22910A, TPS22912C, and TPS22913B/C devices provide reverse current protection in ON and OFF states. An internal reverse voltage parator disables the power-switch when the output voltage (VOUT) is driven higher than the input voltage (VIN), by VRCP, to quickly (10 µs typ) stop the flow of current towards the input side of the switch. Reverse current protection is always active, even when the powerswitch is disabled. Additionally, under-voltage lockout (UVLO) protection turns the switch off if the input voltage is too low. The TPS22913B/C contains a 150-Ω on-chip load resistor for quick output discharge when the switch is turned...
