VDD Monitor
The TC3405 RESET output is in high impedance
provided the voltage at VTH is greater than the internal
voltage reference. This reference is approximately the
same value as the voltage appearing at REFOUT.When
VTH is less than the internal reference, RESET is pulled
low. When VTH rises above the internal reference
voltage again, RESET is held low for the reset active
time-out period, t9, before being released. The RESET
output is valid for VDD =1.3V to 5.5V.
When used to generate a Power-on or Brown-out
Reset, an external resistor network is required to divide
the appropriate VDD threshold down to 1.23V at the
VTH input, (See the Typical Application circuit). For
example, to generate a POR for a VDD at 3V -10%, the
values of R1 and R2 should be 137k
and 115k
respectively.
Since RESET is an open drain, it can be wired-OR’ed
with another open drain or external switch if desired.
