DESCRIPTION
The nanopower TS9001-1/2 analog comparators
guarantee +1.6V operation, draw very little supply
current, and have robust input stages that can
tolerate input voltages beyond the power supply. Both
products are the first analog comparator products in
the “NanoWatt Analog” high-performance analog
integrated circuits portfolio. The TS9001-1/2 draws
600nA of supply current and includes an on-board
+1.252V±1% reference. These comparators are also
electrically and form-factor identical to the MAX9117
and the MAX9118 family of analog comparators. Both
comparators offer a 33% improvement in voltage
reference initial accuracy and the TS9001-1 offers
73% higher output current drive.
The TS9001-1’s push-pull output drivers were
designed to drive 5mA loads from one supply rail to
the other supply rail. The TS9001-2’s open-drain
output stage make it easy to incorporate this analog
comparator into systems that operate on different
supply voltages. Both devices are available in an
ultra-small 5-pin SC70 package.

Electrical and thermal stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These
are stress ratings only and functional operation of the device at these or any other condition beyond those indicated in the operational sections
of the specifications is not implied. Exposure to any absolute maximum rating conditions for extended periods may affect device reliability and
lifetime.

Note 1:
All specifications are 100% tested at T
A
= +25°C. Specification limits over temperature (T
A
= T
MIN
to T
MAX
) are guaranteed by
device characterization, 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 by the edges of the hysteresis band and measured with respect to the center of
the hysteresis band (i.e., V
OS
). See Figure 2.
Note 4:
The propagation delays are specified with an input overdrive (V
OVERDRIVE
) of 100mV and an output load capacitance of
C
L
= 15pF. V
OVERDRIVE
is defined above and is beyond the offset voltage and hysteresis of the comparator input. Reference
voltage error should also be included.
