SNAS659B June 2015 – September 2018 TPL5111
PRODUCTION DATA.
The DELAY/M_DRV pin is sensitive to parasitic capacitance. TI recommends that the traces connecting the resistance on this pin to GROUND be kept as short as possible to minimize parasitic capacitance. This capacitance can affect the initial set up of the time interval. Signal integrity on the DRVn pin is also improved by keeping the trace length between the TPL5111 and the enable input of the LDO/DC-DC converter short to reduce the parasitic capacitance. The EN/ONE_SHOT should to be tied to GND or VDD with short traces, and should never be left floating. The DONE input should never be left floating. If not tied to a µC GPIO, the DONE pin should be tied to ground.
