7.5.2.2 Circuitry

The manual Power ON may be implemented using a switch (momentary mechanical action). The TPL5110 offers two possible approaches according to the power consumption constraints of the application.

For use cases that do not require the lowest power consumption, using a single-pole single-throw switch may offer a lower-cost solution. The DELAY/M_DRV pin may be directly connected to VDD with REXT in the circuit. The current drawn from the supply voltage during the manual power ON is given by VDD/REXT.

The manual MOSFET Power ON function may also be asserted by switching DELAY/M_DRV from REXT to VDD using a single-pole double-throw switch, which will provide a lower power solution for the manual power ON, because no current flows.
