NAME
_______________Detailed Description
Reset Output
A P’s reset input starts the P in a known state. These
P supervisory circuits assert reset to prevent code-
execution errors during power-up, power-down, or
brownout conditions.
RESET and RESET are guaranteed to be asserted at a
valid logic level for VCC > +1V (see the Electrical Char-
acteristics table). Once RESET asserts, it remains
asserted for at least 100ms (tRP) after VCC rises above
its threshold value or after MR returns high (Figures 1
and 2).
Open-Drain RESET Output
The MAX6343 has an active-low, open-drain reset out-
put. This output sinks current when RESET is asserted.
Connect a pull-up resistor from RESET to any positive
supply voltage up to +5.5V (Figure 3). Select a resistor
value large enough to register a logic low (see the Elec-
trical Characteristics table), and small enough to regis-
ter a logic high while supplying all input current and
leakage paths connected to the RESET line. A 10k
pull-up is sufficient in most applications.
Manual Reset
The MAX6342/MAX6343/MAX6344s’ manual-reset input
(MR) allows reset to be triggered by a pushbutton
switch. The switch is effectively debounced by the 1s
min reset pulse width. MR is CMOS-logic compatible.
