... Application information 5.1 Power management The L6382D5 has two stable states (save mode and operating mode) and two additional states that manage the Start-up and fault conditions: the Over Current Protection is a parallel asynchronous process enabled when in operating mode Following paragraphs will describe each mode and the condition necessary to shift between them ...

... Supply section µPUVLO ( Power Under Voltage Lock Out): This block controls the power ● management of the L6382D5 ensuring the right current consumption in each operating state, the correct V up generator switching. During Start-up the device sinks the current necessary to charge the external capacitor on pin V from the high voltage bus ...

... The DIM (Digital Input Monitor) block manages the input signals delivered to the drivers ensuring that they are low during the described start-up procedure; the DIM block controls the L6382D5 behaviour during both save and operating modes. When the voltage on pin CSI overcomes the internal reference of 0.54V (typ.) the block latches the fault condition: in this state the OCP block forces low both HSG and LSG signals while CSO will be forced high ...
