DESCRIPTION
The X40030, X40031, X40034, X40035 combine
power-on reset control, watchdog timer, supply voltage
supervision, second and third voltage supervision, and
manual reset, in one package. This combination lowers
system cost, reduces board space requirements, and
increases reliability.
Applying voltage to VCC activates the power on reset cir-
cuit which holds RESET/RESET active for a period of
time. This allows the power supply and system oscillator
to stabilize before the processor can execute code.
Low VCC detection circuitry protects the user’s system
from low voltage conditions, resetting the system when
VCC falls below the minimum VTRIP1 point.
RESET/RESET is active until VCC returns to proper
operating level and stabilizes. A second and third voltage
monitor circuit tracks the unregulated supply to provide a
power fail warning or monitors different power supply
voltage. Three common low voltage combinations are
available, however, Intersil’s unique circuits allows the
threshold for either voltage monitor to be reprogrammed
to meet specific system level requirements or to fine-tune
the threshold for applications requiring higher precision.
