Startup Method This IC can be started in one of the following two ways: (1) Start the IC by turning on and off the EN pin after applying power to VCC1 and VCC2. (2) Short-circuit the VCC1, VCC2, and EN pins. When using method (1), apply power to VCC1 and VCC2 simultaneously, or in the order of VCC1 to VCC2, then to the EN pin. To shutdown the IC, follow the start-up procedure in reverse order. No.A1415-3/9 LA59700MX Pin Function Pin No. 1 Pin name OUT Output.
