JAJSLG4 december 2022 LM7480
PRODUCTION DATA
The enable pin allows for the gate driver to be either enabled or disabled by an external signal. If the EN/UVLO pin voltage is greater than the rising threshold, the gate driver and charge pump operates as described in Charge Pump section. If EN/UVLO pin voltage is less than the input low threshold, V(ENF), the charge pump and both the gate drivers (DGATE and HGATE) are disabled placing the LM7480 in shutdown mode. If V(ENF) < V(EN/UVLO) < V(UVLOF) then only HGATE is disabled disconnecting the load from the supply, DGATE remains ON. The EN/UVLO pin can withstand a maximum voltage of 65 V. For always ON operation connect EN/UVLO pin to VS.
