SLIS150L March 2014 – February 2023 DRV5013
PRODUCTION DATA
After applying VCC to the DRV5013 device, ton must elapse before the OUT pin is valid. During the power-up sequence, the output is Hi-Z. A pulse as shown in #SLIS1504167 and #SLIS1507792 occurs at the end of ton. This pulse can allow the host processor to determine when the DRV5013 output is valid after start-up. In Case 1 (#SLIS1504167) and Case 2 (#SLIS1507792), the output is defined assuming a constant magnetic field B > BOP and B < BRP.
If the device is powered on with the magnetic field strength BRP < B < BOP, then the device output is indeterminate and can either be Hi-Z or pulled low. During the power-up sequence, the output is held Hi-Z until ton has elapsed. At the end of ton, a pulse is given on the OUT pin to indicate that ton has elapsed. After ton, if the magnetic field changes such that BOP < B, the output is released. Case 3 (#SLIS1504684) and Case 4 (#SLIS150707) show examples of this behavior.
