very short, the
avoids resets at short negative spikes at the output voltage e.g. caused by load changes.
As soon as the output voltage is more positive than the reset threshold, the delay
capacitor is charged with constant current. When the voltage reaches
output RO is set High again.
The reset threshold is either the internal defined
lowered by a voltage level at the RTh input down to 3.5 V. The reset delay time and the
reset reaction time are defined by the external capacitor
down to
The device is capable to supply 150 mA. For protection at high input voltage above 25 V,
the output current is reduced (SOA protection).
Reset
The power on reset feature is necessary for a defined start of the microprocessor when
switching on the application. For the reset delay time after the output voltage of the
regulator is above the reset threshold, the reset signal is set High again. The reset delay
time is defined by the reset delay capacitor
Figure
The undervoltage reset circuitry supervises the output voltage. In case
below the reset threshold the reset output is set LOW after the reset reaction time. The
reset LOW signal is generated down to an output voltage
reaction time and the reset delay time is defined by the capacitor value.
The power on reset delay time is defined by the charging time of an external delay
capacitor
