Texas Instruments Power Distribution Switches, Load Drivers TPS2051AD

The TPS2051AD is a high-side power distribution switch designed for applications that may encounter heavy capacitive loads and short circuits. It features an 80-mW N-channel MOSFET switch capable of delivering up to 500 mA of continuous current per channel. The device operates within a voltage range of 2.7 V to 5.5 V and includes independent thermal and short-circuit protection, ensuring safe operation by limiting output current to a maximum of 0.9 A during overload conditions. The TPS2051AD is equipped with CMOS- and TTL-compatible enable inputs, allowing for flexible control in various applications. It has a typical rise time of 2.5 ms and a maximum standby supply current of 10 mA. The device also incorporates undervoltage lockout and ESD protection, making it suitable for a wide range of environments with an ambient temperature range of 0¬8C to 85¬8C. The product is UL listed, ensuring compliance with safety standards.
