Description
The TSX3702 is a micropower CMOS dual
voltage comparator which exhibits a very low
current consumption of 5 µA typical per
comparator. This device was designed as the
improvement of the TS3702: it shows a lower
current consumption, a better input offset voltage,
and an enhanced ESD tolerance. The TSX3702
is fully specified over a wide temperature range
and is proposed in automotive grade for the SO8
package. It is fully compatible with the TS3702
CMOS comparator and is available with similar
packages. New tiny packages (MiniSO8 and
DFN8 2x2 mm) are also proposed for the
TSX3702 thus allowing even more integration on
applications.

6 Application information (input voltages)
The ESD strategy used in the TSX3702 (and shown in Figure 2) allows input voltages from
-0.3 V up to 16 V to be applied regardless of the VCC+ voltage. When VIN > VCC+ a leakage
current goes from the input through the protection diode to the ESD clamp. This current is
about 0.2 nA at 25 °C and about 250 nA at 125 °C. For a detailed input characteristic see
Figure 12. The device is designed to prevent phase reversal.
