GENERAL DESCRIPTION
The TC1028 is a mixed-function device combining two
general purpose, complimentary output comparators and a
voltage reference in a single 8-pin package.
This increased integration allows the user to replace
two packages, saving space, lowering supply current, and
increasing system performance. The TC1028 operates
down to VDD = 1.8V and requires only 10µA of supply
current. A Shutdown input (SHDN) disables the compara-
tors, placing their outputs in a high-impedance state. The
reference stays active in Shutdown Mode. Standby power
consumption is typically 1µA.
The TC1028 is designed specifically for operation from
a single supply, however, operation from dual supplies is
also possible, and the power supply current drain is inde-
pendent of the magnitude of the power supply voltage.
Packaged in an 8-pin MSOP or 8-pin DIP, the TC1028
is ideal for applications requiring low power level detection.
