TPS22976  
SLVSDE7B –NOVEMBER 2016–REVISED SEPTEMBER 2017  
TPS22976 5.7-V, 6-A, 14-mΩ On-Resistance Dual-Channel Load Switch  
1 Features  
3 Description  
The TPS22976 product family consists of two  
devices: TPS22976 and TPS22976N. Each device is  
a dual-channel load switch with controlled turnon. The  
device contains two N-channel MOSFETs that can  
operate over an input voltage range of 0.6 V to 5.7 V,  
and can support a maximum continuous current of 6

per channel. Each switch is independently  
at VIN = 0.6 V to 5 V, VBIAS = 5 V  
controlled by an on and off input (ON1 and ON2),  
which can interface directly with low-voltage control  
signals. The TPS22976 is capable of thermal  
shutdown when the junction temperature is above the  
threshold, turning the switch off. The switch turns on  
again when the junction temperature stabilizes to a  
safe range. The TPS22976 also offers an optional  
integrated 230-Ω on-chip load resistor for quick  
output discharge when the switch is turned off.
