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.
