2) Fault status output
This function is used to output a fault signal from the FLT pin when an 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 0.01µF and RFLTRLS is set to 200k, the holding time will be set to 2 ms.
tFLTRLS [ms]= CFLTRLS [µF]•RFLTRLS [k]
To set the fault output holding time to “0” ms, only connect the resistor RFLTRLS.

3) Undervoltage Lockout (UVLO) function
The BM6102FV-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(low voltage side typ 4.15V, high voltage side typ 11.5V),
the OUT1 pin and the FLT pin both will output the “L” signal. When the power supply voltage rises to the UVLO OFF
voltage(low voltage side typ 4.25V, high voltage side typ 12.5V), these pins will be reset. However, during the fault output
holding time set in “2) Fault status output” section, the OUT1 pin and the FLT pin will hold the “L” signal. In addition, to
prevent malfunctions due to noises, mask time tUVLO1MSK(typ 10µs) and tUVLO2MSK(typ 10µs) are set on both low and
high voltage sides.
