Specifications

Figure 5-4. Power On Reset (POR) / Brown Out Reset (BOR)

VGH

– This is the V33A threshold where the internal power is declared good. The UCD3138064A

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– This is the V33A threshold where the internal reset signal is no longer valid.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

TPOR

– The time delay from when VGH is exceeded to when the device comes out of reset.

Brown

Out

– This is the V33A voltage threshold at which the device sets the brown out status bit. In

addition an interrupt can be triggered if enabled.
