Descriptions
The DIO70020 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 DIO70020 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 DIO70020 is available in the SOT23-5 package.
It is rated over the -40°C to 85°C temperature
range.
