Select Mode
Operation
The Select Mode
operation is a tri-state input that
allows the user to select V
OUT1
and V
OUT2
from three
different values. By connecting the SELECT pin to
GND, both output voltages (V
OUT1
, V
OUT2
) supply
2.5V. Connecting the SELECT pin to V
IN
results in both
output channels supplying a fixed 3.0V output. Last but
not least, leaving the SELECT pin floating sets both
voltages to 2.8V. This output voltage functionality
provides high design flexibility and minimizes costs
associated with inventory, time-to-market and new
device qualifications.
4.5
RESET Output
The microprocessor supervisor of theTC1305 provides
accurate supply voltage monitoring and reset timing
during power-up, power-down and brown-out condi-
tions. The RESET output is valid to V
DET
= 1.0V (below
this point it becomes an open circuit and does not sink
current) and is able to reject negative going transients
(glitches) on the power supply line. Transient immunity
can further be improved by adding a capacitor close to
the V
DET
pin of the TC1305.
4.6
Turn On Response
The turn on response is defined as two separate
response categories, Wake Up Time (t
WK
) and Settling
Time (t
S
).
The TC1305 has a fast Wake Up Time (10
μ
sec typical)
when released from shutdown. See Figure 4-1 for the
Wake Up Time designated as t
WK
. The Wake Up Time
is defined as the time it takes for the output to rise to 2%
of the V
OUT
value after being released from shutdown.
The total turn on response is defined as the Settling
Time (t
S
), see Figure 4-1. Settling Time (inclusive with
t
WK
) is defined as the condition when the output is
within 2% of its fully enabled value (40
μ
sec typical)
when released from shutdown. The settling time of the
output voltage is dependent on load conditions and
output capacitance on V
OUT
(RC response).
