General Description
The TC1041 is a mixed-function device combining two
comparators and a voltage reference in a single 8-pin
package. The inverting inputs of both comparators are
internally connected to the reference.
This increased integration allows the user to replace
two packages, which saves space, lowers supply
current and increases system performance. The
TC1041 operates from two 1.5V alkaline cells down to
V
DD
= 1.8V. It requires only 10
μ
A typical supply current
which significantly extends battery life. The TC1041
provides a simple method for adding user-adjustable
hysteresis without feedback or complex external
circuitry. Hysteresis is adjusted with a simple resistor
divider on the HYST pin.
Rail-to-rail inputs and outputs allow operation from low
supply voltages with large input and output signal
swings.
Packaged in an 8-Pin SOIC or 8-Pin MSOP, the
TC1041 is ideal for applications requiring low power
and small packages.
