1 / 25 page TPS22934 www.ti.com SLVSAD4 – AUGUST 2010 ULTRA-SMALL, LOW-INPUT-VOLTAGE, LOW rON LOAD SWITCH WITH HYSTERESIS CONTROL INPUT Check for Samples: TPS22934 1 FEATURES DESCRIPTION • Integrated Single-Channel Load Switch • Ultra Small CSP-4 package The TPS22934 is a small, ultra low ON-resistance (rON) load switch with controlled turn on. The devices 0.9 mm x 0.9 mm, 0.5-mm Pitch, 0.5-mm Thick contain a P-channel MOSFETs that can operate over • Input Voltage: 1.5 V to 3.6 V an input voltage range of 1.5 V to 3.6 V. • Ultra-Low ON Resistance The switch is controlled by an on/off input (ON), – rDS(ON) = 63 mΩ at VIN = 3.6 V which has built in hysteresis (VTH+(typ) = 2.35 V) – rDS(ON) = 69 mΩ at VIN = 2.5 V allowing an easy use of TPS22934 in power-rail sequencing applications. – rDS(ON) = 78 mΩ at VIN = 1.8 V – rDS(ON) = 87 mΩ at VIN = 1.5 V In TPS22934 a 35- Ω on-chip load resistor is added for output quick discharge when switch is turned off. • 1-A Maximum Continuous Switch Current • Integrated Hysteresis Enable Input (ON Pin) In TPS22934, the rise time of the device is internally Allows Easy Power Rail Sequencing controlled in order to avoid inrush current. TPS22934 feature a typical rise time of 26 µs with a 3.6-V input. • Controlled Slew Rate Option: 26 µs at 3.6 V The TPS22934 is available in an ultra-small • Quick Output Discharge Transistor space-saving 4-pin CSP package and is • ESD Performance Tested Per JESD 22 characterized for operation over the free-air – 3000-V Human-Body Model temperature range of –40ºC to 85ºC. (A114-B, Class II) TYPICAL APPLICATION – 1000-V Charged-Device Model (C101) 1.8-V Power Rail Sequencing APPLICATIONS • Battery Powered Equipment • Portable Industrial Equipment • Portable Medical Equipment • Portable Media Players • Point Of Sales Terminal • GPS Devices • Digital Cameras • Portable Instrumentation • Smartphones FEATURE LIST SLEW RATE QUICK MAXIMUM rON (TYP) (TYP) OUTPUT OUTPUT ENABLE AT 3.6 V AT 3.6 V DISCHARGE CURRENT Hysteresis Input TPS22934 63 m Ω 26 µs Yes 1 A VTH+(typ) = 2.35 V 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
