Reverse Voltage Protection
When the output voltage exceeds the input voltage by
V
REV
 voltage during T
REV
, the reverse voltage circuitry
disconnects the output in order to protect the power supply.
The same time T
REV
 is needed to turn on again the power
MOS plus a rearming time T
RREV
.
Enable Input
Enable pin must be driven by a logic signal (CMOS or
TTL compatible) or connected to the GND or VIN. A logic
low on EN
 or high on EN turns-on the device. A logic high
on EN
 or low on EN turns off device and reduces the current
consumption down to I
INOFF
.
Blocking Control
The blocking control circuitry switches the bulk of the
power MOS. When the part is off, the body diode limits the
leakage current I
REV
 from OUT to IN. In this mode, anode
of the body diode is connected to IN pin and cathode is
connected to OUT pin. In operating condition, anode of the
body diode is connected to OUT pin and cathode is
connected to IN pin preventing the discharge of the power
supply.
APPLICATION INFORMATION
Power Dissipation
The junction temperature of the device depends on
different contributing factors such as board layout, ambient
temperature, device environment, etc... Yet, the main
contributor in terms of junction temperature is the power
dissipation of the power MOSFET. Assuming this, the
power dissipation and the junction temperature in normal
mode can be calculated with the following equations:

Adjustable Current-Limit Programming
(for adjustable version only)
The   NCP380xMUAJAA   and   NCP380xSNAJAA,
respectively mDFN and TSOP6 packages, are proposed to
have current limit flexibility for end Customer. Indeed, Ilim
pin is available to connect pull down resistor to ground,
which participate to the current threshold adjustment. Its
strongly recommended to use 0.1 or 1% resistor tolerance to
keep the over current accuracy.
For this resistance selection, Customer should define first
of all, the USB current to sustain, without the device enters
in the protection sequence. Main rule is to select this pull
down resistor in order to make sure min current limit is
above the USB current to provide continuously to the
upstream accessory.
Following, the main table selection contains the USB
current port for the accessory, the standard resistor selection
and typical/max over current threshold.
