MAX16122–MAX16125
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
General Description
The MAX16122–MAX16125 pushbutton controllers with
single-supply monitors monitor one or two pushbuttons and
generate a hard reset signal if the buttons are pushed and
held for a setup delay. These devices make it easy to “hide”
the hard reset function in an existing pushbutton, such as a
soft power switch. The devices operate from 1.6V to 5.5V
and consume a quiescent current of only 5µA at 3V.
The MAX16122–MAX16125 have pin-programmable or
resistor-adjustable setup delay. Connect the SEL pin to
GND, VCC, or leave it unconnected to select the different
setup delays (depending on part suffix, see Table 1a) or
connect an external resistor from SEL to GND to set the
setup delays (E suffix only, see Table 1b).
The MAX16124/MAX16125 have one manual reset input
(MR), a reset output (RESET), and a soft reset output
(SRESET) which mirrors the state of the input. The
MAX16122/MAX16123 have two identical manual reset
inputs (MR1 and MR2) and one reset output (RESET). A
deglitch block is connected to each input to add a delay to
the falling edge with a fixed deglitch period of 20ms (tDB).
The devices feature a comparator that monitors the
input supply voltage. A variety of factory-trimmed threshold
options accommodate different supply voltages and
tolerances, eliminating external components. The factoryset reset thresholds range from 1.58V to 4.63V to monitor
5V, 3.3V, 2.5V, and 1.8V supplies.
The MAX16122–MAX16125 are offered in a tiny 0.86mm
x 1.27mm, 6-bump WLP package and are specified over
the automotive temperature range (-40°C to +125°C).

Active-Low Reset Output. RESET is either an open-drain or a push-pull output (see the
Selector Guide). RESET asserts low when VCC drops below the selected threshold and
remains low for the VCC reset timeout period after VCC rises above the reset threshold.
The RESET one-shot asserts low for the reset timeout period when the manual reset
input is asserted longer than the setup delay. The open-drain output requires an external
pullup resistor.

Detailed Description
The MAX16122–MAX16125 low-current microprocessor
reset circuits feature single or dual manual reset inputs
with an extended setup period. The devices also feature
an internal comparator to monitor 5V, 3.3V, 2.5V, and 1.8V
supplies.
When the monitored supply voltage drops below the
specified threshold, the active-low RESET output asserts
low and remains low for the reset timeout period (tRP).
The RESET output is one-shot pulse asserted for the
reset timeout period. For applications that do not require
reset timeout period at startup, devices with that configuration are offered. Supply voltage reset threshold is
selectable through part suffix, see Table 3.
Connect SEL to GND, VCC, or leave unconnected to
select the different setup delays (depending on part suffix,
see Table 1a), or connect to an external resistor to set the
setup delays (E suffix only, see Table 1b).
The MAX16124/MAX16125 have one manual reset input
(MR), one reset output (RESET), and one soft reset
output (SRESET). The MAX16122/MAX16123 have two
identical manual reset inputs (MR1 and MR2) and one
reset output (RESET). A deglitch block is connected to
each manual reset input to add a delay to the falling edge
with a fixed deglitch period of 20ms (tDB).
www.maximintegrated.com
Resistor-Adjusted Setup Delay
For the MAX16122–MAX16125 with the E setup delay
suffix (MAX1612_WTE_+T), a resistor connected from
SEL to GND sets the setup delay. Table 1b shows common resistor values and the resulting setup delays. For
resistor values not in the table, use the following formula
to compute the setup delay:
t SU =
R
20
where R is the resistor value in kΩ and tSU is the resulting setup delay in seconds. For best results, use resistor
values between 10kΩ and 500kΩ.
Reset Output
The reset output is typically connected to the reset
input of a microprocessor (µP). A µP’s reset input starts
or restarts the FP in a known state. The MAX16122–
MAX16125 FP supervisory circuits provide the reset
logic to prevent code-execution errors during power-up,
power-down, and brownout conditions (see the Typical
Operating Characteristics).
The MAX16122/MAX16123 have a reset output RESET.
The MAX16124/MAX16125 have a reset output RESET
and a soft-reset output SRESET which is the debounced
“mirror image” of MR (see Figure 1a).
Maxim Integrated │ 7
MAX16122–MAX16125
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
All reset outputs are either active-low open-drain or
active-low push-pull (see the Selector Guide). RESET
changes from high to low whenever the monitored voltage
VCC drops below the reset threshold voltage. Once VCC
exceeds its respective reset threshold voltage, RESET
remains low for the reset timeout period (tRP) and then
goes high. RESET is one-shot pulsed whenever selected
manual reset inputs are asserted longer than the setup
delay (tSU). RESET stays asserted for the normal reset
timeout period.
RESET is guaranteed to be in the proper output
logic state for VCC ≥ 0.95V. For applications requiring valid reset logic when VCC is less than 0.95V,
see the Ensuring a Valid RESET Output Down to
VCC = 0V (Push-Pull RESET Output) section.
Manual Reset Input
Each device in the MAX16122–MAX16125 family includes
at least one manual reset input, which must be held logiclow for an extended setup period (tSU) before the RESET
output asserts. An internal pullup resistor is connected to
each manual reset input. When valid manual reset input
conditions/setup periods are met, the RESET output is
pulsed low for the reset timeout period (see Table 2).
Existing front-panel pushbutton switches (i.e., poweron/-off, channel up/down, or mode select) can be used
to drive the manual reset inputs. The extended manual
reset setup period prevents nuisance system resets during normal front-panel usage or resulting from inadvertent
short-term pushbutton closure.
The MAX16124/MAX16125 include a single manual reset
input (MR) and two reset outputs (RESET and SRESET).
The MAX16122/MAX16123 include two manual reset
inputs (MR1 and MR2) and one reset output, RESET. For
dual MR1 and MR2 devices, both inputs must be simultaneously pulled low and held for the extended setup period
(tSU) before the reset output is pulsed. The dual extended
setup provides greater protection from nuisance resets.
The MAX16122–MAX16125 RESET output is asserted
once for the reset timeout period after each valid manual
reset input condition. At least one manual reset input
must be released (go high) and then be driven low for
the extended setup period before RESET asserts again.
Internal timing circuitry debounces low-to-high manual
reset logic transitions, so no external circuitry is required.

MAX16122–MAX16125
Supply Voltage Monitor
The MAX16122–MAX16125 have an internal comparator
with a programmable trip threshold to monitor the supply voltage. The VCC monitoring thresholds are selectable through the part number suffix (see the Ordering
Information and Table 3).
Applications Information
Falling VCC Transients
In addition to issuing a reset to the µP during power-up,
power-down, and brownout conditions, the MAX16122–
MAX16125 are relatively immune to short-duration falling VCC transients (glitches). The Typical Operating
Characteristics show the Maximum Transient Duration
vs. VCC Overdrive graph for which the MAX16122–
MAX16125 do not generate a reset pulse. This graph was
generated using a falling pulse applied to VCC starting
above the actual reset threshold and ending below the
threshold by the magnitude indicated (VCC overdrive).
The graph indicates the typical maximum pulse width that
a falling transient can have without initiating a reset pulse.
As the magnitude of the transient increases (go farther
below the reset threshold), the maximum allowable pulse
width decreases.
Ensuring a Valid RESET Output Down to
VCC = 0V (Push-Pull RESET Output)
The MAX16122–MAX16125 guarantee proper operation
down to VCC = 0.95V. In applications that require valid
reset levels down to VCC = 0V, add a pulldown resistor between RESET and GND for the push-pull outputs
www.maximintegrated.com
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
(MAX16122/MAX16124). The resistor sinks any stray
leakage currents, holding RESET low (Figure 2). The
resistor value used is not critical, but it must be small
enough not to overload the RESET output when VCC
is above the reset threshold. For most applications, use
100kΩ to 1MΩ. This scheme does not work with opendrain outputs of the MAX16123/MAX16125.
