Pin Description
Detailed Description
The
Typical Operating Circuit
shows a typical connec-
tion for the MAX6361/MAX6363/MAX6364 family. OUT
powers the static random-access memory (SRAM). OUT
is internally connected to V
CC
if V
CC
is greater than the
reset threshold, or to the greater of V
CC
or V
BATT
when
V
CC
is less than the reset threshold. OUT can supply up
to 150mA from V
CC
. When V
CC
is higher than V
BATT
, the
BATT ON (MAX6363) output is low. When V
CC
is lower
than V
BATT
, an internal MOSFET connects the backup
battery to OUT. The on-resistance of the MOSFET is a
function of backup-battery voltage and is shown in the
Battery to Out On-Resistance vs. Temperature graph in
the
Typical Operating Characteristics
section.
Backup-Battery Input. When V
CC
falls below the reset threshold, BATT switches to OUT if V
BATT
is 20mV
greater than V
CC
. When V
CC
rises 20mV above V
BATT
, V
CC
switches to OUT. The 40mV hysteresis
prevents repeated switching if V
CC
falls slowly.

MAX6363
Battery-On Output. BATT ON goes high in battery backup mode.
BATT ON
MAX6364
Reset Input. When RESET IN falls below 1.235V, reset is asserted. Reset output remains
asserted as long as RESET IN is low and for at least 150ms (t
RP
) after RESET IN goes high.
RESET IN
Supply Voltage. Reset is asserted when V
CC
drops below the reset threshold voltage (V
TH
). Reset
remains asserted until V
CC
rises above V
TH
and for at least 150ms after V
CC
rises above V
TH
.

Output. OUT sources from V
CC
when it is above the reset threshold (V
TH
), and from the greater of V
CC
or
BATT when V
CC
is below V
TH
.

MAX6361
Manual-Reset Input. Maintaining logic low on
MR
asserts a reset. Reset output remains assert-
ed for at least 150ms (t
RP
) after
MR
transitions from low to high. Leave unconnected or connected to V
CC
if not used.

Active-Low Reset Output (for L and P versions).
RESET
remains low while V
CC
is below the reset thresh-
old and for at least 150ms (t
RP
) after V
CC
rises above the reset threshold.
RESET
also asserts when
MR
or RESET IN is low.
RESET
Active-High Reset Output (for H versions). RESET remains high while V
CC
is below the reset threshold
and for at least 150ms (t
RP
) after V
CC
rises above the reset threshold. RESET also asserts when
MR
or
RESET IN is low.
