W83793G
9.3.3 Power On Reset
The power-on reset threshold is 4.3V (typical). When Vcc crosses this threshold, the internal reset
signal will be asserted for 3uS. During this time period, W83793G is in the reset state. When the
internal reset signal is de-asserted, W83793G is in the operating state.
In the operating state, if Vcc drops below 4.0V and then rises above 4.3V, the internal reset signal will
be asserted immediately. Fig 1 illustrates the reset mechanism.
