SNAS681A February 2017 – September 2021 TPL5110-Q1
PRODUCTION DATA
The gate of the MOSFET is connected to the DRV pin. When DRV= LOW, the MOSFET is turned ON. The pulse generated at DRV is equal to the selected time interval period, minus 50ms. It is shorter in the case of a DONE signal received from the µC. If the DONE signal is not received within the programmed time interval (minus 50ms), the DRV signal will be high for the last 50ms of the time interval in order to turn off the MOSFET before the next cycle starts.
The default value (after resistance reading) is HIGH. The signal is sent out from the TPL5110-Q1 when the programmed time interval starts. When the DRV is LOW, the manual power ON signal is ignored.
