SLVSCP6H July 2014 – June 2020 DRV10983
The DRV10983 includes a 3.3-V LDO and an 1.8-V LDO. The 3.3-V LDO is powered by Vreg and 1.8-V LDO is powered by 3.3-V LDO. The 1.8-V LDO is for internal circuit only. The 3.3-V LDO is mainly for internal circuits, but can also drive external loads not to exceed IV3P3_MAX listed in the Electrical Characteristics. For example, it can work as a pullup voltage for the FG, DIR, SDA, and SCL interface.
Both V1P8 and V3P3 capacitor must be connected to GND.
