Abstract
The present disclosure relates generally to power-on-reset (POR) devices for activation of a circuit block powered by a battery. The POR devices activate a circuit block when a battery voltage level of a battery voltage generated by the battery is above a dead battery condition voltage level. So that the circuit block is activated after the battery voltage level of the battery voltage has reached the dead battery condition voltage level, the POR device includes a trigger circuit. The trigger circuit is operable to receive the battery voltage and is configured to generate a trigger signal in response to the battery voltage level being charged above a trigger voltage level, which is equal to or greater than the dead battery condition voltage level. The POR circuit is also operable to generate a POR signal in an activation state and activate the circuit block.
