3 Description
The TLC3702-Q1 consists of two independent micro-
power voltage comparators. Compared to similar
devices, the TLC3702-Q1 uses one-twentieth of the
power for similar response times. This allows the
device to react quickly to fast changing signals while
extending the battery life.
The push-pull CMOS output stage drives capacitive
loads directly without a power consuming pullup
resistor to achieve the stated response time.
Eliminating the pullup resistor not only reduces power
dissipation but also saves board space and
component cost. Additionally, the output stage is fully
compatible with all TTL and CMOS logic
requirements.
Texas Instruments’ LinCMOS™ process offers
superior analog performance versus standard CMOS
processes. Along with the standard CMOS
advantages of low power without sacrificing speed,
high input impedance and low bias currents, the
LinCMOS process offers extremely stable input/offset
voltages with large differential input voltages. This
characteristic makes it possible to build reliable
CMOS comparators.
The TLC3702-Q1 has a wide supply range from 3 V
to 16 V, allowing design flexibility. The voltage range
also allows the device to handle start-stop
applications and be connected directly to a standard
12-V battery. All of these features make the
TLC3702-Q1 suitable for HEV/EV and powertrain
system such as transmission control unit (TCU) and
engine control.
