Texas Instruments Power Distribution Switches, Load Drivers TPS2048AD

The TPS2048AD is a power distribution switch designed for applications involving heavy capacitive loads and potential short circuits. It features an 80-m,Ѷ high-side N-channel MOSFET switch capable of handling up to 250 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 under overload conditions. This switch incorporates a charge pump for gate drive, allowing for controlled rise and fall times to minimize current surges during switching. It also has a current limit set at 0.5 A, with an overcurrent logic output that indicates when the current limit is exceeded. The TPS2048AD supports CMOS and TTL-compatible enable inputs and has a typical rise time of 2.5 ms. Additionally, it features an undervoltage lockout and a maximum standby supply current of 10 mA for single and dual configurations. The device is housed in a 16-pin SOIC package and is rated for operation in ambient temperatures from 0¬8C to 85¬8C.
