TPS22968x Dual Channel, Ultra-Low Resistance Load Switch
1 Features
•1 Integrated Dual Channel Load Switch
• Input Voltage Range: 0.8 V to 5.5 V
• VBIAS Voltage Range: 2.5 V to 5.5 V
– Ideal for 1S Battery Configuration
• Ultra-Low R_ON Resistance
– R_ON = 27 mΩ at V_IN = 5 V (V_BIAS = 5 V)
– R_ON = 25 mΩ at V_IN = 3.3 V (V_BIAS = 5 V)
– R_ON = 25 mΩ at V_IN = 1.8 V (V_BIAS = 5 V)
• 4-A Maximum Continuous Switch Current per
Channel
• Low Quiescent Current
– 55 µA at V_BIAS = 5 V (Both Channels)
– 55 µA at V_BIAS = 5 V (Single Channel)
• Low Control Input Threshold Enables Use of
1.2-V/1.8-V/2.5-V/3.3-V Logic
• Configurable Rise Time⁽¹⁾

• Telecom Systems
3 Description
The TPS22968x is a small, ultra-low R_ON, dual-
channel load switch with controlled turn on. The
device contains two N-channel MOSFETs that can
operate over an input voltage range of 0.8 to 5.5 V
and can support a maximum continuous current of 4
A per channel. Each switch is independently
controlled by an on/off input (ON1 and ON2), which is
capable of interfacing directly with low-voltage control
signals. In TPS22968, a 270-Ω on-chip load resistor
is added for output quick discharge when switch is
turned off.
The TPS22968x is available in a small, space-saving
package (DPU) with integrated thermal pad allowing
for high power dissipation. The device is
characterized for operation over the free-air
temperature range of –40 to +105°C.
