The TPS2561QDRCRQ1 from Texas Instruments is a dual-channel power distribution switch designed for applications requiring precise current limiting or handling heavy capacitive loads and short circuits. It offers an adjustable current limit threshold per channel, ranging from 250 mA to 2.8 A (typical), set via an external resistor.
This device features two 44 mΩ high-side MOSFETs and operates within a voltage range of 2.5 V to 6.5 V. The switch rise and fall times are controlled to minimize current surges during turn-on or turn-off. Each channel limits output current to a safe level by switching into a constant-current mode when the output load exceeds the set threshold.
Key specifications include a maximum standby supply current of 2 µA, built-in soft-start functionality, and system-level ESD capability of 15 kV or 8 kV. The TPS2561QDRCRQ1 is qualified for automotive applications and meets USB current-limiting requirements. It is available in a 10-VSON (3x3 mm) package.
This power switch is suitable for various automotive applications where robust power management and protection are essential. Its adjustable current limit and fast overcurrent response make it ideal for protecting sensitive circuitry from overloads and short circuits.
