DESCRIPTION
The Intersil X45620 combines power-on reset control,
battery switch circuit, watchdog timer, supply voltage
supervision, secondary voltage supervision, block lock
protect and serial EEPROM in one package. This
combination lowers system cost, reduces board space
requirements, and increases reliability.
Applying power to the device activates the power-on
reset circuit which holds RESET active for a period of
time. This allows the power supply and oscillator to
stabilize before the processor can execute code.
A system battery switch circuit compares V
CC
(V1MON)
with V
BATT
input and connects V
OUT
to whichever is
higher. This provides voltage to external SRAM or other
circuits in the event of main power failure. The X45620
can drive 50mA from V
CC
and 250μA from V
BATT
. The
device switches to V
BATT
when V
CC
drops below the
low V
CC
voltage threshold and V
BATT >
V
CC
.
