Texas Instruments TPS2043 Manuals

The TPS2043 and TPS2053 are triple power distribution switches with a maximum resistance of 135 mΩ, 5 V input, and a continuous current of 500 mA per channel. It has short circuit protection and overcurrent logic output, operating voltage range of 2.7 V to 5.5 V, logic level enable input, 2.5 ms typical rise time, undervoltage lockout, 20 µA maximum standby supply current, bidirectional switch, available in 16-pin SOIC package, ambient temperature range of -40°C to 85°C, 2 kV Human-Body-Model, 200-V Machine-Model ESD protection, UL listed-File No. E169910.

The TPS2043 and TPS2053 triple power distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2043 and the TPS2053 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 that is compatible with 5-V logic 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 TPS2043 and TPS2053 limit the output current to a safe level by switching into low-conduction state.

The TPS2043 and TPS2053 triple power distribution switches are triple channel power switches, using 135-mΩ N-channel MOSFET, support 5-V and 3-V logic, with internal charge pump, support 2.7-V input voltage, short circuit protection current is 500 mA, overcurrent protection current is 200 mA.
