Functional description

4.1

Power supply and voltage reference

The internal regulator circuit (shown in Figure 4) consists of a start-up circuit, an internal

voltage preregulator, the bandgap voltage reference and the bias block that provides current

to all the blocks.

The starter gives the start-up currents to the whole device when the input voltage goes high

and the device is enabled (inhibit pin connected to ground).

The preregulator block supplies the bandgap cell with a preregulated voltage V

a very low supply voltage noise sensitivity.

REG

4.2

Voltages monitor

An internal block senses continuously the VCC, VREF and VBG. If the voltages go higher than

their thresholds, the regulator starts to work. There is also an hysteresis on the VCC (UVLO).
