MAX16122–MAX16125
Dual Pushbutton Controllers in
Tiny 6-Bump WLP Package
Supply Voltage Monitor
The MAX16122–MAX16125 have an internal comparator
with a programmable trip threshold to monitor the sup-
ply voltage. The V CC monitoring thresholds are select-
able through the part number suffix (see the Ordering
Information and Table 3 ) .
Applications Information
Falling V CC Transients
In addition to issuing a reset to the F P during power-up,
power-down, and brownout conditions, the MAX16122–
MAX16125 are relatively immune to short-duration fall-
ing V CC transients (glitches). The Typical Operating
Characteristics show the Maximum Transient Duration
vs. V CC Overdrive graph for which the MAX16122–
MAX16125 do not generate a reset pulse. This graph was
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 V CC is
above the reset threshold. For most applications, use
100k I to 1M I . This scheme does not work with open-
drain outputs of the MAX16123/MAX16125.
Layout and Bypassing
Ensure 0.1 F F (minimum) capacitance is connected from
V CC to GND.
V CC
generated using a falling pulse applied to V CC starting
above the actual reset threshold and ending below the
threshold by the magnitude indicated (V CC 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 allow-
able pulse width decreases.
Ensuring a Valid RESET Output Down to
V CC = 0V (Push-Pull RESET Output)
The MAX16122–MAX16125 guarantee proper operation
down to V CC = 0.95V. In applications that require valid
reset levels down to V CC = 0V, add a pulldown resis-
tor between RESET and GND for the push-pull outputs
