The devices contain • Ultra-Low ON Resistance N-channel MOSFETs that can operate over an input – rDS(ON) = 5.7 mΩ at VIN = 3.6 V voltage range of 0.75 V to 3.6 V. An integrated – rDS(ON) = 5.8 mΩ at VIN = 2.5 V charge pump biases the NMOS switch to achieve a minimum switch ON resistance. The switch is – rDS(ON) = 5.9 mΩ at VIN = 1.8 V controlled by an on/off input (ON), which is capable of – rDS(ON) = 6 mΩ at VIN = 1.2 V interfacing directly with low-voltage control signals. – rDS(ON) = 8 mΩ at VIN = 0.75 V A 1250- Ω on-chip load resistor is added for output • Ultra Small CSP-6 package quick discharge when switch is turned off. The rise 0.9 mm x 1.4 mm, 0.5-mm Pitch time of the device is internally controlled to avoid • 2-A Maximum Continuous Switch Current inrush current. The TPS22924C features a rise time of 800 µs at 3.6 V. • Low Shutdown Current The TPS22924C is available in an ultra-small • Low Threshold Control Input space-saving 6-pin CSP package and is • Controlled Slew Rate to Avoid Inrush Currents characterized for operation over the free-air • Quick Output Discharge Transistor temperature range of –40ºC to 85ºC. • ESD Performance Tested Per JESD 22 TYPICAL APPLICATION – 5000-V Human-Body Model (A114-B, Class II) – 1000-V Charged-Device Model (C101) APPLICATIONS • Battery Powered Equipment NOTE: SMPS = Switched-mode power supply • Portable Industrial Equipment • Portable Medical Equipment • Portable Media Players • Point Of Sales Terminal • GPS Devices • Digital Cameras • Netbooks / Notebooks • Smartphones Table 1.
