3 / 27 page BD2046AFJ BD2056AFJ Datasheet Absolute Maximum Ratings (Ta=25°C) Parameter Symbol Rating Unit Supply Voltage VIN -0.3 to +6.0 V Enable Voltage VEN, V/EN -0.3 to +6.0 V /OC Voltage V/OC -0.3 to +6.0 V /OC Current I/OC 10 mA OUT Voltage VOUT -0.3 to +6.0 V Storage Temperature Tstg -55 to +150 °C Power Dissipation Pd 0.67(Note 1) W (Note 1) Mounted on 70mm x 70mm x 1.6mm glass-epoxy PCB. Derating : 5.4mW/ oC above Ta=25 oC Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.
