Interfacing to µPs with Bidirectional Reset Pins
Since the RESET output on the SS8038L is open drain,
this device interfaces easily with µPs that have bidirec-
tional reset pins, such as the Motorola 68HC11. Con-
necting the µP supervisor’s RESET output directly to
the microcontroller’s (µC’s) RESET pin with a single
pull-up resistor allows either device to assert reset (Fig-
ure 3).
8038L Open-Drain RESET Output Allows Use with
Multiple Supplies
Generally, the pull-up connected to the SS8038L will
connect to the supply voltage that is being monitored at
the IC’s VCC pin. However, some systems may use the
open-drain output to level-shift from the monitored supply
to reset circuitry powered by some other supply (Figure
4). Note that as the SS8038L’s V CC decreases below 1V,
so does the IC’s ability to sink current at RESET . Also,
with any pull-up, RESET will be pulled high as VCC de-
cays toward 0. The voltage where this occurs depends
on the pull-up resistor value and the voltage to which it is
connected.
Benefits of Highly Accurate Reset Threshold
Most µP supervisor ICs have reset threshold voltages
between 5% and 10% below the value of nominal supply
voltages. This ensures a reset will not occur within 5% of
the nominal supply, but will occur when the supply is 10%
below nominal.
When using ICs rated at only the nominal supply ±5%,
this leaves a zone of uncertainty where the supply is be-
tween 5% and 10% low, and where the reset may or
may not be asserted.
The SS803xx463/803xx308 use highly accurate circuitry
to ensure that reset is asserted close to the 5% limit, and
long before the supply has declined to 10% below nomi-
nal.
