APPLICATIU
Resetting a Fault Latch (LTC4252-1)
The latched circuit breaker fault of LTC4252-1 benefits
from long cooling time. It is reset by pulling the UV pin
below V
UVLO
with a switch. Reset is also accomplished by
pulling the V
IN
pin momentarily below (V
LKO
– V
LKH
). A
third reset method involves pulling the TIMER pin below
V
TMRL
as shown in Figure 14. An initial timing cycle is
skipped if TIMER is used for reset. An initial timing cycle
is generated if reset by the UV pin or the V
IN
pin.

MOMENTARY DPST SWITCH RESET
The duration of the TIMER reset pulse should be smaller
than the time taken to reach 0.2V at SS pin. With a single
pole mechanical pushbutton switch, this may not be
feasible. A double pole, single throw pushbutton switch
removes this restriction by connecting the second switch
to the SS pin. With this method, both the SS and TIMER
pins are released at the same time (see Figure 19).
