General Description
The AOZ1375DI is a bidirectional current-limited load switch
intended for applications that require circuit protections. The
device operates from voltages between 3.4 V and 23 V and
features two power terminals, VINT and VBUS, which are
rated at 28 V Absolute Maximum. When used as source
switch, the internal current limiting circuit protects the supply
from large load current. The current limit can be set with
an external resistor. The back-to-back switch configuration
blocks any leakage between VINT and VBUS pins when the
device is disabled.
The AOZ1375DI provides over-voltage protection,
short-circuit protection and thermal protection function
that limit excessive power dissipation. The over-voltage
protection threshold is selectable by an external resistor.
The internal soft-start circuitry controls inrush current due
to highly capacitive loads. The soft-start can be adjusted
using an external capacitor. It consumes less than 5 μA in
shutdown.
The AOZ1375DI-01 is available in a 3 mm x 3 mm DFN-12L
package which can operate over -40°C to +85°C temperature
range.
