description  
The TPS2045 and TPS2055 power-distribution switches are intended for applications where heavy capacitive  
loads and short circuits are likely. Each of these 135-mΩ N-channel MOSFET high-side power switches is  
controlledbyalogicenablecompatiblewith5-Vand3-Vlogic. Gatedriveisprovidedbyaninternalchargepump  
that controls 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 TPS2045 and TPS2055 limit  
the output current to a safe level by switching into a constant-current mode, pulling the overcurrent (OC) 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 TPS2045 and TPS2055 are designed to limit at 0.44-A load. These power-distribution switches, available  
in 8-pin small-outline integrated circuit (SOIC) and 8-pin plastic dual-in-line packages (PDIP), operate over an  
ambient temperature range of –40°C to 85°C.
