8.4.1 State Diagram

The device has three main categories of states it can transition into and out of low quiescent current, normal operation, and limp home. Inside of each of the categories are several states the device can be in. The state diagram for the TPS2HCS10A-Q1 device is shown in Figure 8-21 and the state diagram for the TPS2HCS10B-Q1 device is shown in Figure 8-22.
