NCP382
Fixed Current-Limiting
Power-Distribution
Switches
The NCP382 is a single input dual outputs high side
power−distribution switch designed for applications where heavy
capacitive loads and short−circuits are likely to be encountered. The
device includes an integrated 80 mW, P−channel MOSFET. The
device limits the output current to a desired level by switching into a
constant−current mode when the output load exceeds the current−limit
threshold or a short is present. The current−limit threshold is internally
fixed. The power−switches rise and fall times are controlled to
minimize current ringing during switching.
The FLAG logic output asserts low during overcurrent or
overtemperature conditions. The switch is controlled by a logic enable
input active high or low.
