Latched output level when STROBE is
H when the operable range (3 V typical) or higher and L when lower.
When one of V
When one of TSD or ISD is operating, the system resets (OR relationship).
Function of overcurrent protection circuit
Until the RESET signal is input after ISD is triggered, the overcurrent protection circuit remains in operation.
During ISD, the charge pump stays halted.
When TSD and ISD are operating, the charge pump halts.
