2.1 Digital Output (V_OUT)
V_OUT goes low when V_IN drops below V_DET – and
returns high when V_IN rises above V_DET – + V_HYST.
(See Figure 3-1).
2.2 Analog Input (V_IN)
V_IN can be used for power supply monitoring or a
voltage level that requires monitoring.

2.3 Ground Terminal (V_SS)
V_SS provides the negative reference for the analog
input voltage. Typically, the circuit ground is used.
