device. Two main modes are available by setting logic pins. First mode
is Direct Mode from Wall−Adapter to the system. In this mode the
system is both positive and negative over−voltage protected up to
+28 V and down to −28 V. The wall adapter (or AC/DC charger) is
disconnected from the system if the input voltage exceeds the
overvoltage (OVLO) or undervoltage (UVLO) thresholds. At power
up, the V

allows an external accessory to be powered by the system battery or
boost converter. Here the external accessory would be connected to the
device input (bottom connector of system) and the device battery
would be at the device output. In this case overcurrent protection is
activated to prevent accessory faults and battery discharge. Thanks to
the NCP370 using an internal NMOS, the system cost and the PCB
area of the application board are minimized.
