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. 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. In addition, the device has ESD−protected input (15 kV Air) when bypassed with a 1 mF or larger capacitor. • • • 8 1 DFN8 MU SUFFIX CASE 506BP MARKING DIAGRAM 1 XX MG G XX = Specific Device Code M = Date Code G = Pb−Free Device (*Note: Microdot may be in either location) PIN ASSIGNMENT IN Features • • • • • • • • • • • • http://onsemi.com 1 8 GND Overvoltage Protection Up to + 30 V 7 FLAG VBAT 2 OUT Fast Turn Off Time NC 3 6 GS Very Low Current Consumption/USB Compliant 5 EN ILIM 4 Li ion Battery Voltage Monitoring Overvoltage Lockout (OVLO) (Top View) Undervoltage Lockout (UVLO) Overcurrent Protection Externally Adjustable (OCP) up to 2.8 A ORDERING INFORMATION Thermal Shutdown See detailed ordering, marking and shipping information in the package dimensions section on page 12 of this data sheet.

Functional Block Diagram http://onsemi.com 2 NCP367 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 VBAT INPUT Li ion Battery voltage sense pin. A serial resistor must be placed between this pin and positive pin of the battery pack. 3 NC OUTPUT Not Connected 4 ILIM 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. 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 GS INPUT Gain Select Pin. When the GS pin is tied to 0 level, the Overcurrent threshold is defined by Ilimit setting. See logic table. When GS pin is tied to high, the Overcurrent threshold is set to Ilimit/GS 7 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 internal 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 GND POWER Ground. 9 OUT 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.

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. 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. 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 RILIM resistor, in example. Undervoltage, Overvoltage, Overcurrent and thermal faults are signalized thanks to the open drain FLAG pin, by pulling its down. 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, OVBAT, IOCP 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 10 kW) must be provided to VCC. FLAG pin is an open drain output, which is able to support 1 mA maximum. 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. Overcurrent Protection (OCP) This device integrates the overcurrent protection function, from wall adapter to battery. That means the current across the internal PMOS is regulated and cut when the value, set by external RSEL resistor, exceeds ILIM longer than tREG. An internal resistor is placed in series with the pin allowing to have a maximum OCP value when ILIM pin is directly connected to GND. By adding external resistors in series with ILIM and GND, 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). 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 Undervoltage Lockout (UVLO) 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) 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. http://onsemi.com 9 NCP367 to this option, both fast charge or USB charge are authorized with the same device. RLIM (kW) = 249 / IOCP − 165 NCP367OxMUxxTBG RLIM (kW) = 532 / IOCP − 180 During overcurrent event, charge area is opened and FLAG output is tied to low, allowing the mController to take into account the fault event and then open the charge path. At power up (accessory is plugged on input pins), the current is limited up to ILIM during 1.8 ms (typical), to allow capacitor charge and limit inrush current. If the ILIM threshold is exceeded over 1.8 ms, the device enter in OCP burst mode until the overcurrent event disappears. IOCP (mA) 1500 1000 GS = Low VBAT Sense 500 The connection of the VBAT pin to the positive connection of the Li ion battery pack allows preventing overvoltage transient, greater than 4.35 V. In case of wrong charger conditions, the PMOS is then opened, eliminating Battery pack over voltage which could create safety issues and temperature increasing. The 4.35 V comparator has a 150 mV built−in hysteresis. More of that, deglitch function of 2 ms is integrated to prevent voltage transients on the Battery voltage. If the battery over voltage condition exceeds deglitch time, the charge path is opened and FLAG pin is tied to low level until the VBAT is greater than 4.35 V – hysteresis. At wall adapter insertion, and if the battery is fully charged, Vbat comparator stays locked until battery needs to be recharged (4.2 V typ − 4.1 V min). A serial resistor has to be placed in series with Vbat pin and battery connection, with a 200 kW recommended value. GS = High 0 0 100 200 300 400 500 Rilim(kW) 600 700 800 Figure 12.
