description  
The TPS2042 and TPS2052 dual power distribution switches are intended for applications where heavy  
capacitive loads and short circuits are likely to be encountered. The TPS2042 and the TPS2052 incorporate  
in single packages two 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 that is compatible with 5-V logic  
and 3-V logic. 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 TPS2042 and TPS2052 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.  
The TPS2042 and TPS2052 are designed to limit at 0.9-A load. These power distribution switches are available  
in 8-pin small-outline integrated circuit (SOIC) and 8-pin plastic dual-in-line packages (PDIP) and operate over  
an ambient temperature range of –40°C to 85°C.
