Texas Instruments TPS2051 Manuals

TPS2041, TPS2051 are 135-mΩ N-channel MOSFET high-side power switches with 500mA continuous current, short-circuit and thermal protection and overcurrent logic output. They are intended for applications where heavy capacitive loads and short circuits are likely to be encountered.

The TPS2041 and TPS2051 power distribution switches are designed for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2041 and the TPS2051 are 135-mΩ N-channel MOSFET high-side 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 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 TPS2041 and TPS2051 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 occur, the TPS2041 and TPS2051 automatically disconnect the load power, protecting the system.
