2) Fault status output
This function is used to output a fault signal from the FLT pin when a fault occurs (i.e., when the undervoltage lockout
function (UVLO), short current protection function (SCP) or thermal protection function is activated) and hold the Fault
signal until the set Fault output holding time is completed. The Fault output holding time tFLTRLS is given as the following
equation with the settings of capacitor CFLTRLS and resistor RFLTRLS connected to the FLTRLS pin. For example, when
CFLTRLS is set to 0.01F and RFLTRLS is set to 200k, the holding time will be set to 2 ms.
tFLTRLS [ms]= CFLTRLS [F]•RFLTRLS [k]
To set the fault output holding time to “0” ms, only connect the resistor RFLTRLS.

3) Undervoltage Lockout (UVLO) function
The BM6103FV-C incorporates the undervoltage lockout (UVLO) function both on the low and the high voltage sides.
When the power supply voltage drops to the UVLO ON voltage, the OUT pin and the FLT pin both will output the “L”
signal. When the power supply voltage rises to the UVLO OFF voltage, these pins will be reset. However, during the fault
output holding time set in “2) Fault status output” section, the OUT pin and the FLT pin will hold the “L” signal. In addition,
to prevent malfunctions due to noises, mask time tUVLO1MSK and tUVLO2MSK are set on both low and high voltage sides.
