1 Features
•1 Integrated Single Channel Load Switch
• Input Voltage Range: 0.8 V to 5.7 V
• Ultra-Low On Resistance (R_ON)
– R_ON = 16 mΩ at VIN = 5 V (VBIAS = 5 V)
– R_ON = 16 mΩ at VIN = 3.6 V (VBIAS = 5 V)
– R_ON = 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

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.
