Description
The TPS2553QDBVRQ1 power-distribution switch is designed for applications that need precise current limiting or that include significant capacitive loads and short circuits. It can deliver a continuous load current of up to 1.5 A. An external resistor can be used to program a current-limit threshold between 75 mA and 1.7 A (typical). At the higher current-limit levels, current-limit accuracy of up to ±6% can be reached. To minimize current surges during turn on and off, the rise and fall times of the power switch are managed.
When the output load exceeds the current-limit threshold, the TPS2553QDBVRQ1 device uses a constant-current mode to limit the output current to a safe level. To protect devices on the input side of the switch, an inbuilt reverse-voltage comparator disables the power switch when the output voltage is driven higher than the input voltage. During overcurrent and reverse-voltage circumstances, the FAULT output asserts low.
