†
The TPS2045A through TPS2048A and TPS2055A  
through TPS2058A power-distribution switches are  
intended for applications where heavy capacitive  
loads and short circuits are likely to be encountered.  
NC  
†
All enable inputs are active high for the TPS205xA series.  
NC – No connect  
These 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, these devices limit 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. These power-distribution switches are designed to current limit at  
0.5 A.
