Description

Digital Output

Analog Input

Ground Terminal

Analog Input

2.1 Digital Output (VOUT)

VOUT goes low when VIN drops below VDET – and

returns high when VIN rises above VDET – + VHYST.

(See Figure 3-1).

2.2 Analog Input (VIN)

VIN can be used for power supply monitoring or a

voltage level that requires monitoring.

2.3 Ground Terminal (VSS)

VSS provides the negative reference for the analog

input voltage. Typically, the circuit ground is used.

2.4 No Connect (NC)

No internal connection.
