Descriptions
The DIO703 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 DIO703A/B/C provide separately
350mA/500mA/1A three current levels.
The DIO703 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 DIO703 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.
