Figure 9. Power On Reset (POR) / Brown Out Reset (BOR)

VGH –

This is the V33A threshold where the internal power is declared good. The UCD3138xA comes

out of reset when above this threshold.

VGL –

This is the V33A threshold where the internal power is declared bad. The device goes into reset

when below this threshold.

Vres –

This is the V33A threshold where the internal reset signal is no longer valid. Below this threshold

the device is in an indeterminate state.

IReset –

This is the internal reset signal. When low, the device is held in reset. This is equivalent to holding

the reset pin on the IC low.
