5. STANDBY FUNCTION
The
μ
PD168002 realizes a standby function by combination of an input signal.
The specified output is set to high impedance (Hi-Z) status by setting STB to low level.
Each pin can be independently controlled, and can be set to standby status of the self current consumption of the IC
reduced as much as possible by setting all pins to low level. In the standby status, the overheat protection circuit and
the undervoltage lockout circuit do not operate.
