8.5.2.2 Circuitry

The manual reset may be implemented using a switch (momentary mechanical action). The TPL5010 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_RST pin may be directly connected to VDD with R_EXT in the circuit. The current drawn from the supply voltage during the reset is given by VDD/R_EXT.

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