Figure 2: Continuous-Time Application, B < B_RP
This figure illustrates the use of a quick cycle for chopping V_CC in order to conserve battery power. Position 1, power is applied to the
device. Position 2, the output assumes the correct state at a time prior to the maximum Power-On Time, t_PO(max). The case shown is where
the correct output state is HIGH_ . Position 3, t_PO(max) has elapsed. The device output is valid. Position 4, after the output is valid, a control unit
reads the output. Position 5, power is removed from the device.
