SLVS749A – NOVEMBER 2008 – REVISED DECEMBER 2008 LOW INPUT VOLTAGE, ULTRA-LOW rON LOAD SWITCHES • PDAs • Input Voltage: 0.9 V to 3.6 V • Cell Phones • Ultra-Low ON Resistance • GPS Devices – rON = 14 mΩ at VIN = 3.6 V • MP3 Players – rON = 20 mΩ at VIN = 2.5 V • Peripheral Ports – rON = 33 mΩ at VIN = 1.8 V • Portable Media Players – rON = 67 mΩ at VIN = 1.2 V • RF Modules – rON = 116 mΩ at VIN = 1.0 V • 2-A Maximum Continuous Switch Current • Ultra-Low Quiescent Current: 78 nA at 1.8 V TPS22921, TPS22922, and TPS22922B are ultra-low • Ultra-Low Shutdown Current: 35 nA at 1.8 V rON load switches with controlled turn on. TPS22921/2/2B contain an ultra-low rON P-channel • Low Threshold Control Input Enable the use of MOSFET that can operate over an input voltage 1.2V/1.8V/2.5V/3.3V Logic range of 0.9 V to 3.6 V. The switch is controlled by an • Controlled Slew Rate to Avoid Inrush Currents on/off input (ON), which is capable of interfacing – TPS22921 and TPS22922: 30 µS directly with low-voltage control signals. In TPS22922 and in TPS22922B, a 120- Ω on-chip load resistor is – TPS22922B: 200 µS added for output quick discharge when switch is • ESD Performance Tested Per JESD 22 turned off. The rise time (slew rate) of the device is – 3000-V Human-Body Model internally controlled in order to avoid inrush current: (A114-B, Class II) TPS22921 and TPS22922 feature a 30 µs rise time whereas TPS22922B is 200 µs. – 1000-V Charged-Device Model (C101) • Six Terminal Wafer-Chip-Scale Package TPS22921, TPS22922, and TPS22922B feature ultra low quiescent and shutdown current and are available – 0.9 mm × 1.4 mm, 0.5 mm Pitch, in space-saving 6-terminals wafer-chip-scale 0.5 mm Height packages (WCSP: YZP with 0.5-mm pitch and YFP – 0.8 mm × 1.2 mm, 0.4 mm Pitch, with 0.4-mm pitch) which make it ideal for portable 0.5 mm Height electronics. The devices are characterized for operation over the free-air temperature range of –40°C to 85°C.
