BD63620AEFV
○MTH／Current decay mode-setting terminal
This is the terminal to set the current decay mode. Current decay mode can be optionally set according to input voltage.
MTH terminal input voltage[V] Current decay mode
0~0.3
SLOW DECAY
0.4~1.0
MIX DECAY
1.5~3.5
FAST DECAY
Please connect to GND if using at SLOW DECAY mode.
Please avoid using with MTH terminal open because if MTH terminal is open, the input is unsettled, and then there is the
danger that PWM operation becomes unstable. Besides, please take into consideration the outflow current (max.2μA) if
inputted by resistance division when selecting the resistance value.
○TEST terminal／Terminal for inspection
This terminal is used for delivery inspection on IC, and shall be grounded before use.
In addition, malfunctions may be caused by application without grounding.
○NC terminal
This terminal is unconnected electrically with IC internal circuit.
