description  
The TPS2047 and TPS2057 triple power-distribution switches are intended for applications where heavy  
capacitive loads and short circuits are likely. These devices incorporate in single packages three 135-mΩ  
N-channel MOSFET high-side power switches for power-distribution systems that require multiple power  
switches. Each switch is controlled by a logic enable compatible with 5-V and 3-V logic. Gate drive is provided  
by an internal charge pump that controls the power-switch rise times and fall times to minimize current surges  
during switching. The charge pump, requiring no external components, 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 TPS2047 and TPS2057 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  
causingthejunctiontemperaturetorise, athermalprotectioncircuitshutsofftheswitchinovercurrenttoprevent  
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 TPS2047 and TPS2057 are designed to limit at 0.44-A load. These power-distribution switches are  
available in 16-pin small-outline integrated circuit (SOIC) packages and operate over an ambient temperature  
range of –40°C to 85°C.
