| 14 | STAT1 | output | Open-drain status output that pulls down during Diode 1 forward conduction; it can be left open or grounded when not used. |
| 15 | OUT1 | power_out | Diode 1 cathode and output of the LTC4415; bypass with a ceramic capacitor of at least 4.7µF, pins 15 and 16 are fused together, and they should be left open when not used. |
