Feature Description (continued)
8.3.3 Power-On Time
After applying V_CC to the DRV5013-Q1 device, t_on must elapse before the OUT terminal is valid. During the
power-up sequence, the output is Hi-Z. A pulse as shown in Figure 13 and Figure 14 occurs at the end of t_on.
This pulse can allow the host processor to determine when the DRV5013-Q1 output is valid after startup. In Case
1 (Figure 13) and Case 2 (Figure 14), the output is defined assuming a constant magnetic field B > B_OP and B <
B_RP.
