1 Features
•1 Integrated Single Channel Load Switch • Input Voltage Range: 0.8 V to 5.7 V • Ultra-Low On Resistance (RON)
– RON = 16 mΩ at VIN = 5 V (VBIAS = 5 V) – RON = 16 mΩ at VIN = 3.6 V (VBIAS = 5 V) – RON = 16 mΩ at VIN = 1.8 V (VBIAS = 5 V) • 6-A Maximum Continuous Switch Current • Low Quiescent Current (50 µA) • Low Control Input Threshold Enables Use of 1.2-, 1.8-, 2.5-, and 3.3-V Logic • Configurable Rise Time • Quick Output Discharge (QOD) (Optional) • SON 8-pin Package With Thermal Pad • ESD Performance Tested per JESD 22 – 2000-V HBM and 1000-V CDM
2 Applications
• Ultrabook™ • Notebooks and Netbooks • Tablet PC • Consumer Electronics • Set-top Boxes and Residential Gateways • Telecom Systems • Solid State Drives (SSDs)
3 Description
The TPS22965x is a single channel load switch that provides configurable rise time to minimize inrush current. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8 V to 5.7 V and can support a maximum continuous current of 6 A. The switch is controlled by an on and off input (ON), which is capable of interfacing directly with low-voltage control signals. In the TPS22965, a 225-Ω on-chip load resistor is added for quick output discharge when switch is turned off.
The TPS22965x is available in a small, space-saving 2-mm × 2-mm 8-pin SON package (DSG) with integrated thermal pad allowing for high power dissipation. The device is characterized for operation over the free-air temperature range of –40°C to +105°C.
