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.
