●Description
of pins and cautions on layout of board
1）VCC1 (Input-side power supply pin)
The VCC1 pin is a power supply pin on the input side. To suppress voltage fluctuations due to the current to drive
internal transformers, connect a bypass capacitor between the VCC1 and the GND1 pins.
2）GND1 (Input-side ground pin)
The GND1 pin is a ground pin on the input side.
3）VCC2 (Output-side power supply pin)
The VCC2 pin is a power supply pin on the output side. To reduce voltage fluctuations due to OUT1, OUT2 pin output
current and due to the current to drive internal transformers, connect a bypass capacitor between the VCC2 and the
GND2 pins.
4）GND2 (Output-side ground pin)
The GND2 pin is a ground pin on the output side. Connect the GND2 pin to the emitter / source of a power device.
5）IN (Control input terminal)
The IN pin is a pin used to determine output logic.

6）FLT (Fault output pin)
The FLT pin is an open drain pin used to output a fault signal when a fault occurs (i.e., when the undervoltage lockout
function (UVLO), short current protection function (SCP) or thermal protection function is activated).
This pin is I/O pin and if L voltage is externally input, the output is set to L status regardless of other input logic.
Consequently, be sure to connect the pull-up resistor between VCC1 pin and the FLT pin even if this pin is not used.

(When UVLO, SCP or thermal protection is activated)
7）FLTRLS (Fault output holding time setting pin)
The FLTRLS pin is a pin used to make setting of time to hold a fault signal. Connect a capacitor between the FLTRLS
pin and the GND1 pin, and a resistor between it and the VCC1 pin.
The fault signal is held until the FLTRLS pin voltage exceeds a voltage set with the V
FLTRLS
parameter. To set holding
time to 0 ms, do not connect the capacitor. Short-circuiting the FLTRLS pin to the VCC1 pin will cause a high current to
flow in the FLTRLS pin and, in an open state, may cause the IC to malfunction. To avoid such trouble, be sure to
connect a resistor between the FLTRLS and the VCC1 pins.
8）OUT1 (Output pin)
The OUT1 pin is a pin used to drive the gate of a power device.
9）OUT2 (MOS FET control pin for Miller Clamp)
The OUT2 pin is a pin for controlling the external MOS switch for preventing increase in gate voltage due to the miller
current of the power device connected to OUT1 pin.
10）PROOUT (Soft turn-off pin)
The PROOUT pin is a pin used to put the soft turn-off function of a power devise in operation when the SCP function is
activated. This pin combines with the gate voltage monitoring pin for Miller Clamp function.
11）SCPIN (Short current detection pin), SCPTH (Short current detection threshold setting pin)
The SCPIN pin is a pin used to detect current for short current protection. When the SCPIN pin voltage exceeds a
voltage set with the SCPTH pin voltage, the SCP function will be activated. This may cause the IC to malfunction in an
open state. To avoid such trouble, short-circuit the SCPIN pin to the GND2 pin and SCPTH pin to the VCC2 pin if the
short current protection is not used. In order to prevent the wrong detection due to noise, the noise mask time t
SCPMSK
is
set.
12）VTSIN(Thermal detection pin), VTSTH (Thermal detection threshold setting pin)
The VTSIN pin is a temperature sensor voltage input pin, which can be used for thermal protection of a power device.
If VTSIN pin voltage becomes VTSTH pin voltage or less, OUT1 pin is set to L. In the open status, the IC may
malfunction, so be sure to supply the VTSIN more than VTSTH if the thermal protection function is not used. In order to
prevent the wrong detection due to noise, the noise mask time t
TSMSK
is set.

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 t
FLTRLS
is given as the following
equation with the settings of capacitor C
FLTRLS
and resistor R
FLTRLS
connected to the FLTRLS pin. For example, when
C
FLTRLS
is set to 0.01
F and R
FLTRLS
is set to 200k, the holding time will be set to 2 ms.

3) Undervoltage Lockout (UVLO) function
The BM60013FV-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 OUT1 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 OUT1 pin and the FLT pin will hold the “L” signal. In
addition, to prevent malfunctions due to noises, mask time t
UVLO1MSK
and t
UVLO2MSK
are set on both low and high
voltage sides.
