Description

The DIO75530 is power distribution switch intended

for applications where precision current limiting is

required or heavy capacitive loads and short circuits

are encountered. The device provides up to 2.31 A of

continuous load current. When the voltage is higher

than the maximum voltage of 5%, the chip could be

maintained for at least 10 ms without damage.

A programmable current-limit threshold is offered

between 200 mA and 2.59 A (typ) via an external

resistor. Current-limit accuracy is ±10% at 1 A. The

power-switch rise and fall times are controlled to

minimize current surges during turning on/off. A

constant-current mode is used when the output load

exceeds the current-limit threshold.

The DIO75530 limits the output current to a safe level

by using a constant-current mode when the output

load exceeds the current-limit threshold. An internal

reverse voltage comparator disables the power

switch when the output voltage is driven higher than

the input to protect devices on the input side.
