SLVSD14A June 2017 – June 2020 DRV10983-Q1
The DRV10983-Q1 device includes a 3.3-V LDO and a 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 circuits only. The 3.3-V LDO is mainly for internal circuits, but can also drive external loads not to exceed IV3P3_MAX. For example, it can work as a pullup voltage for the FG, DIR, SDA, and SCL interface.
Both the V1P8 and V3P3 capacitors must be connected to GND.
