 Description

The DIO70040 power distribution switch is intended

for applications where precision current limiting is

required or heavy capacitive loads and short circuits

are encountered. The power switch rising and falling

times are controlled to minimize current surges

during turning on / off.

The DIO70040 provides 3 A current limit.

The DIO70040 device limits the output current under

a safe level by using a constant current mode when

the output load exceeds the current limit threshold.

The DIO70040 is available in the SOT23-5, SOIC-8,

EP-MSOP8 and MSOP-8 packages. It is rated over

the -40°C to 85°C temperature range.
