Figure 2. Continuous-Time Application, B < BRP.. This figure illustrates the use of a quick cycle for chopping VCC 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, tPO(max).
The case shown is where the correct output state is HIGH. Position 3, tPO(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.
