TEXAS INSTRUMENTS TPS2041A TPS2042A TPS2043A TPS2044A TPS2051A TPS2052A TPS2053A TPS2054A CURRENT-LIMITED POWER-DISTRIBUTION SWITCHES handbook
The TPS2041A through TPS2044A and TPS2051A through TPS2054A power-distribution switches are intended for applications where heavy capacitive loads and short circuits are likely to be encountered. These devices incorporate 80-mΩ N-channel MOSFET high-side power switches for power-distribution systems that require multiple power switches in a single package. Each switch is controlled by an independent logic enable input. 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, these devices limit the output current to a safe level.

Questions answered in these manuals
What logic level enables the TPS2041A power switch?
A logic low on the EN pin turns on the power switch for TPS2041A.
What is the typical rise time of the driver circuitry?
The driver’s typical rise time is 2.5 ms.
What is the maximum continuous current per channel?
Each channel can handle up to 500 mA continuously.
What voltage range does the device operate in?
The switches operate from 2.7 V up to 5.5 V.
What does the ENx enable input do?
ENx controls the power switch; a logic low (or high, depending on the series) turns the switch on, while the opposite logic level turns it off.
What type of MOSFET is used in the power switch?
The power switch uses an N‑channel MOSFET.
