MARKING
The NCP370 is an overvoltage, overcurrent and reverse control
device. Two main modes are available by setting logic pins. First mode
is Direct Mode from Wall−Adapter to the system. In this mode the
system is both positive and negative over−voltage protected up to
+28 V and down to −28 V. The wall adapter (or AC/DC charger) is
disconnected from the system if the input voltage exceeds the
overvoltage (OVLO) or undervoltage (UVLO) thresholds. At power

The second mode (see Tables 1 & 2), called the Reverse Mode,
allows an external accessory to be powered by the system battery or
boost converter. Here the external accessory would be connected to
the device input (bottom connector of system) and the device battery
would be at the device output. In this case overcurrent protection is
activated to prevent accessory faults and battery discharge. Thanks to
the NCP370 using an internal NMOS, the system cost and the PCB
area of the application board are minimized.

Current Limit Pin. This pin provides the reference, based on the internal band−gap voltage reference, to

Reverse Charge Control Pin. In combination with DIR, the internal N−MOSFETs are turned on if Battery
is applied on the OUT pin (See Tables 1 & 2). In reverse mode, the internal overcurrent protection is
activated. When reverse mode is disabled, the NCP370 current consumption, into OUT pin, is drastically
decreased to limit battery discharge.
Direct Mode Pin. In combination with REV, the internal N−MOSFETs are turned on if a wall adapter
AC−DC is applied on the IN pins (See Tables 1 & 2). The device enters in shutdown mode when this pin
is tied to a high level and the REV pin is tied to high. In this case the output is disconnected from input.
The state of this pin does not have an impact on the fault detect of the FLAG pin.

TYPICAL OPERATING CHARACTERISTICS
Operation
Overvoltage Lockout (OVLO)
The NCP370 provides overvoltage protection for positive
and negative voltages, up to 28 V or down to −28 V on
IN pins. At powerup, with DIR pin = low, REV = high, the
output rises 30 ms after the input rises above the UVLO. The
NCP370 provides a FLAG output, which alerts the system
that a fault has occurred. The FLAG signal rises 30 ms after
the output signal rises.
To protect connected systems on Vout pin from
overvoltage, the device has a built−in overvoltage lock out
(OVLO) circuit. During overvoltage condition, the output is
disabled as long as the input voltage exceeds OVLO.
Additional OVLO thresholds can be manufactured
(Please contact your ON Semiconductor representative for
availability).
A Reverse Mode is available when an accessory is
connected on IN pins and the internal battery is applied on
the OUT pin, allowing the accessory to be powered. In this
mode, no supply must be connected on IN pins and REV pin
must be tied to low level. The NCP370 provides overcurrent
protection for the battery from current faults in the
accessory.
FLAG output will be low since V is higher than OVLO.
This circuit has a 80 mV hysteresis to provide noise
immunity to transient conditions.

Negative Voltage and Reverse Current.
The device protects the downstream side from negative
voltage occurring on the IN pin, down to −28 V. When a
negative voltage occurs, the output is disconnected from the
IN pins.
By adding external resistors in series from I to GND,
the OCP value is lowered. The typical overcurrent threshold
can be calculated with the following formula;

R
(kW) = (60 / I ) − 36

Reverse Mode
In Reverse Mode, an external accessory plugged into the
bottom connector can be powered by the internal battery of
the system.
To access to the reverse mode, DIR pin must be tied high
(> 1.2) and REV must be tied high to low (< 0.55 V).
In this case, the core of the NCP370 will be supplied by
the battery, with a 2.5 V minimum voltage and 5.5 V
maximum voltage.
In this reverse state, both OCP and thermal modes are
available.
Overcurrent Protection (OCP)
This device integrates the reverse over current protection
function, from battery to external accessory.
That means the current across the internal NMOS is

Thermal Shutdown Protection
PCB Recommendations
In case of internal overheating, the integrated thermal
shutdown protection turns off the internal MOSFETs in
order to instantaneously decrease the device temperature.
The thermal threshold has been set at 150°C FLAG then
goes low to inform the MCU.
As the thermal hysteresis is 30°C, the MOSFETs will turn
on as soon the device temperature falls below 120°C.
If the fault event is still present, the temperature increase
engages the thermal shutdown again until the fault event
disappears.
Since the NCP370 integrates the 1. 3A N−MOSFETs,
PCB rules must be respected to properly evacuate the heat
out of the silicon.
From an applications standpoint, PAD1 of the NCP370
package should be connected to an isolated PCB area to
increase the heat transfer if necessary.
In any case, PAD1 should be not connected to any other
potential or GND other than the isolated extra copper
surface.
To assist in the design of the transfer plane connected to
PAD1, Figure 7 shows the copper area required with respect
to R
.
