MAXIM MAX9117, MAX9120 Technical data

General Description

The MAX9117–MAX9120 nanopower comparators in
space-saving SC70 packages feature Beyond-the­Rails™ inputs and are guaranteed to operate down to
+1.6V. The MAX9117/MAX9118 feature an on-board

1.252V ±1.75% reference and draw an ultra-low supply
current of only 600nA, while the MAX9119/MAX9120
(without reference) require just 350nA of supply current.
These features make the MAX9117–MAX9120 family of
comparators ideal for all 2-cell battery-monitoring/man­agement applications.

The unique design of the output stage limits supply-cur­rent surges while switching, virtually eliminating the sup­ply glitches typical of many other comparators. This
design also minimizes overall power consumption under
dynamic conditions. The MAX9117/MAX9119 have a
push-pull output stage that sinks and sources current.
Large internal-output drivers allow rail-to-rail output
swing with loads up to 5mA. The MAX9118/MAX9120
have an open-drain output stage that makes them suit­able for mixed-voltage system design. All devices are
available in the ultra-small 5-pin SC70 package.

ELECTRICAL CHARACTERISTICS—MAX9119/MAX9120 (without REF) (continued)

(VCC= +5V, VEE= 0V, VCM= 0V, TA= -40°C to +85°C, unless otherwise noted. Typical values are at TA= +25°C.) (Note 1)

Note 1: All specifications are 100% tested at T

A

= +25°C. Specification limits over temperature (TA= T

MIN

to T

MAX

) are guaranteed

by design, not production tested.

Note 2: V

OS

is defined as the center of the hysteresis band at the input.

Note 3: The hysteresis-related trip points are defined as the edges of the hysteresis band, measured with respect to the center of

the band (i.e., V

OS

) (Figure 2).

Note 4: Specified with an input overdrive (V

OVERDRIVE

) of 100mV, and load capacitance of CL= 15pF. V

OVERDRIVE

is defined
above and beyond the offset voltage and hysteresis of the comparator input. For the MAX9117/MAX9118, reference voltage
error should also be added.
