NCP367
Battery Charge Front-End Protection, USB and AC/DC Supply Compliant
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.
Features
• Overvoltage Protection Up to + 30 V
• Fast Turn Off Time
• Very Low Current Consumption/USB Compliant
• Li ion Battery Voltage Monitoring
• Overvoltage Lockout (OVLO)
• Undervoltage Lockout (UVLO)
• Overcurrent Protection Externally Adjustable (OCP) up to 2.8 A
• Thermal Shutdown
• Shutdown EN and Gain Input Pins
• Soft−Start to Eliminate Inrush Current
• Alert FLAG Output
• Compliance to IEC61000−4−2 (Level 4)
8 kV (Contact), 15 kV (Air)
• ESD Ratings: Machine Model = B
ESD Ratings: Human Body Model = 2
• 8 Lead DFN 2.2x2 mm Package
• These are Pb−Free Devices
T ypical Application
• USB Devices
• Mobile Phones
• Peripheral

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).
