PIN TYPE(1) DESCRIPTION APPLICATION INFORMATION
NO. NAME
1 VDD P Supply voltage
2 GND G Ground
3 DELAY/ M_DRV I Time interval set and manual MOSFET Power ON Resistance between this pin and GND is used to select the time interval. The manual MOSFET power ON switch is also connected to this pin.
4 DONE I Logic Input for watchdog functionality Digital signal driven by the µC to indicate successful processing.
5 DRV O Power Gating output signal generated every tIP The Gate of the MOSFET is connected to this pin. When DRV = LOW, the MOSFET is ON.
6 EN/ ONE_SHOT I Selector of mode of operation When EN/ONE_SHOT = HIGH, the TPL5110-Q1 works as a TIMER. When EN/ONE_SHOT = LOW, the TPL5110-Q1 turns on the MOSFET one time for the programmed time interval. The next power on of the MOSFET is enabled by the manual power ON.
