The TPS2080, TPS2081, and TPS2082 dual and the  
TPS2085,  
TPS2086  
and  
TPS2087  
quad  
power-distribution switches are intended for  
applications where heavy capacitive loads and short  
circuits are likely to be encountered.  
The TPS208x devices incorporate 80-mΩ N-channel MOSFET high-side power switches for power-distribution  
systems that require multiple power switches in a single package. Each switch is controlled by an independent  
logic enable input. Gate drive is provided by an internal charge pump designed to control the power-switch rise  
times and fall times to minimize current surges during switching. The charge pump requires no external  
components and allows operation from supplies as low as 2.7 V.  
When the output load exceeds the current-limit threshold or a short is present, the TPS208x limits the output  
current to a safe level by switching into a constant-current mode, pulling the overcurrent (OCx) logic output low.  
When continuous heavy overloads and short circuits increase the power dissipation in the switch causing the  
junction temperature to rise, a thermal protection circuit shuts off the switch to prevent damage. Recovery from a  
thermal shutdown is automatic once the device has cooled sufficiently. Internal circuitry ensures the switch  
remains off until valid input voltage is present. The TPS208x devices are designed to current limit at 1.0-A load.
