NCP367
Battery Charge Front-End
Protection, USB and AC/DC
Supply Compliant
NCP367 is a charge path protection device which allows
disconnecting the systems from its output pin in case wrong charging
conditions are detected. The system is positive overvoltage protected
up to +30 V. Thanks to a very low current consumption, the USB
charge is compatible with this integrated component.

This device uses internal PMOS FET, making external devices
unnecessary, which reduces the system cost and PCB area of the
application board. First, NCP367 is able to instantaneously
disconnect the output from the input if the input voltage exceeds the
overvoltage threshold. Additional overcurrent protection function
allows turning off internal PMOS FET when the charge current
exceeds current limit, which is externally selectable.

MARKING DIAGRAM
The current limit value can be modified with control logic pin to
divide it by internal gain, allowing USB 100 mA/500 mA charging or
USB/Wall adapter charging up to overcurrent threshold. At the same
time, Li ion Battery voltage is continuously monitored, providing
more safety during the charge. Thermal shutdown protection is also
available.
NCP367 provides a negative going flag (FLAG) output, which
alerts the system that a fault has occurred as overvoltage (power
supply or battery voltage), overcurrent or thermal event.

PIN FUNCTION DESCRIPTION
Pin
Name
Type
Description
1
IN
POWER Input Voltage Pin. This pin is connected to the power supply: Wall Adapter or USB. A 1 mF low ESR
ceramic capacitor, or larger, must be connected between this pin and GND.
2
V
BAT
INPUT
Li ion Battery voltage sense pin. A serial resistor must be placed between this pin and positive pin of
the battery pack.
3
4
NC
OUTPUT Not Connected
I
OUTPUT Current Limit Pin. This pin provides the reference, based on the internal band−gap voltage reference, to
limit the overcurrent, across internal PMOSFET, from IN to OUT. A 1% tolerance, or better, resistor
shall be used to get the highest accuracy of the Overcurrent Limit.
LIM
5
EN
INPUT
Enable Mode Pin. The device enters in shutdown mode when this pin is tied to a high level. In this case
the output is disconnected from the input. The state of this pin does not have an impact on the fault
detection of the FLAG pin.
6
7
GS
INPUT
Gain Select Pin. When the GS pin is tied to 0 level, the Overcurrent threshold is defined by Ilimit set-
ting. See logic table. When GS pin is tied to high, the Overcurrent threshold is set to Ilimit/GS
FLAG
OUTPUT Fault Indication Pin. This pin allows an external system to detect fault condition. The FLAG pin goes
low when input voltage is below UVLO threshold, exceeds OVLO threshold, charge current from wall
adapter to battery exceeds programmed current limit, Li ion Battery voltage (4.3 V) is exceeded or in-
ternal temperature exceeds thermal shutdown limit. Since the FLAG pin is open drain functionality, an
external pull−up resistor to VBattery must be added (10 kW minimum value).
8
9
GND
OUT
POWER Ground.
OUTPUT Output Voltage Pin. This pin follows IN pin when “no input fault” is detected. The output is disconnected
from the Vin power supply when voltage, current or thermal fault events are detected. A 1 mF low ESR
ceramic capacitor, or larger, must be connected between this pin and GND.

APPLICATION INFORMATION
Operation
FLAG output is tied to low as long as Vin is higher than
OVLO. This circuit has a 100 mV hysteresis to provide
noise immunity to transient conditions.
The NCP367 is an integrated IC which offers a complete
protection of the portable devices during the Li ion battery
charge.
First, the input pin is protected up to +30 V, protecting
the down stream system (charger, transceiver, system...)
against the power supply transients such as inrush current
or defective functionality. Additional protection level is
offered with the overcurrent block which eliminates
current peak or opens the charge path if an overcurrent
default appears.
FLAG Output
NCP367 provides a FLAG output, which alerts external
systems that a fault has occurred.
This pin is tied to low as soon as the OVLO, OV , I
BAT OCP
or internal temperature thresholds are exceeded and
remains low until between minimum driving voltage and
UVLO threshold. When Vin level recovers normal
condition, FLAG is held high. The pin is an open drain
output, thus a pull up resistor (typically 1 MW − Minimum
More of that, the battery voltage is monitored all along
the input power supply is connected, allowing to open
charge path if Li ion battery voltage exceeds 4.3 V, caused
by CCCV charger or battery pack fault.
10 kW) must be provided to V . FLAG pin is an open drain
CC
output, which is able to support 1 mA maximum.
The integrated pass element (PMOS FET) is sized to
support very high charge DC current up to 2.3 A. The
overcurrent threshold can be externally adjusted with a
pull−down resistor and gain select pin is available to divide
current limit threshold with internal fixed gain. Allowing
to adjust with logic pin the overcurrent threshold if
USB/500 mA or WA/1.5 A is detected, without changing
EN Input
To enable normal operation, the EN pin shall be forced
to low or connected to ground. A high level on the pin,
disconnects OUT pin from IN pin. EN does not overdrive
a UVLO or OVLO fault.

REG
Undervoltage Lockout (UVLO)
An internal resistor is placed in series with the pin
allowing to have a maximum OCP value when I
directly connected to GND.
By adding external resistors in series with I
the OCP value is decreased.
An additional logic pin, GS (gain select), is very useful
in case of different charge rate is necessary (Wall adapter
and USB, for example).
To ensure proper operation under any conditions, the
device has a built−in undervoltage lock out (UVLO)
circuit. During Vin positive going slope, the output remains
disconnected from input until Vin voltage is above 1.85 V
plus hysteresis nominal. This circuit has a 80 mV
hysteresis to provide noise immunity to transient condition.

Overvoltage Lockout (OVLO)
By setting GS to 0.4 V, overcurrent thresholds are
depending on R select resistor, which is connect between
pin 4 and GND. When the GS pin is tied to 1.2 V (high logic
level) the preselected current limit is divided by 2.75. Due
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
remains disabled as long as the input voltage exceeds this
threshold.

During overcurrent event, charge area is opened and

charger conditions, the PMOS is then opened, eliminating
Battery pack over voltage which could create safety issues

ESD Tests
NCP367 includes an internal PMOS FET to protect the
systems, connected on OUT pin, from positive
over−voltage. Regarding electrical characteristics, the
NCP367 fully support the IEC61000−4−2, level 4 (Input
pin, 1 mF mounted on board). That means, in Air condition,
Vin has a 15 kV ESD protected input. In Contact condition,
Vin has 8 kV ESD protected input. Please refer to Figure 16
to see the IEC 61000−4−2 electrostatic discharge waveform.
