The TPS2049DR from Texas Instruments is a single-channel, N-channel power distribution switch designed for robust power management in applications prone to heavy capacitive loads and short circuits. This device operates within an input voltage range of 2.7V to 5.5V and provides a continuous current limit of 100mA with a typical on-resistance of 400mOhm.
Key features include thermal and short-circuit protection, undervoltage lockout (UVLO), and a deglitched fault report output. The switch is controlled via a logic-level enable input, which is active low. The internal charge pump manages gate drive, controlling rise and fall times to minimize switching surges. The device is housed in an 8-SOIC package, suitable for surface mounting.
With a quiescent supply current of 43μA and a standby current of only 1μA, the TPS2049DR is an efficient choice for power-sensitive designs. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for a variety of environmental conditions.
