Step-up capacitor
EN=1, VSS3=VDD
Step-up capacitor
EN=1, VSS2=VDD
Step-up capacitor
Output voltage regulator terminal. Provides the voltage between V1 and GND
through a resistive voltage divider.
Master or slave control signal.
MAIN=1, master unit
MAIN=0, slave unit
This pin control whole chip power. This chip will work when this pin is connected
to ground. And whole chip will disable when connect to VDD voltage.
EN=0 and MAIN=1 the chip will generate VSS2+, VSS2-
VSS3, VSS4, VOUT, LOAD signal and internal RC clock.
EN=1, standby mode
