PDB 48 I, PD Inverted Power-Down input pin
Typically connected to a processor GPIO with a pulldown. When PDB input is brought HIGH, the device is enabled and internal registers and state machines are reset to default values. Asserting PDB signal low will power down the device and consume minimum power. The default function of this pin is PDB = LOW; POWER DOWN with an weak (>100-kΩ) internal pulldown enabled. PDB should remain low until after power supplies are applied and reach minimum required levels.
