DESCRIPTION
The TSM9117–TSM9120 family of nanopower
comparators is electrically and form-factor identical to
the MAX9117-MAX9120 family of analog
comparators. Ideally suited for all 2-cell battery-
management/monitoring applications, these 5-pin
SC70 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. The TSM9117 and the
TSM9118 draw 600nA of supply current and include
an on-board 1.252V ±1.75% reference. The
comparator-only TSM9119 and the TSM9120 draw a
supply current of 350nA.
The TSM9117 and TSM9119’s push-push output
drivers were designed to drive 5mA loads from one
supply rail to the other supply rail. The TSM9118 and
the TSM9120’s open-drain output stages make it
easy to incorporate these comparators into systems
that operate on different supply voltages.

Note 1: All specifications are 100% tested at TA = +25°C. Specification limits over temperature (TA = TMIN to TMAX) are guaranteed by
design, not production tested.
Note 2: VOS 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, measured with respect to the center of the
hysteresis band (i.e., VOS) (See Figure 2).
Note 4: Specified with an input overdrive (VOVERDRIVE) of 100mV, and load capacitance of CL = 15pF. VOVERDRIVE is defined above and
beyond the offset voltage and hysteresis of the comparator input. For the TSM9117/TSM9118, reference voltage error should
also be added.
