资料介绍
Microchip's TC54 series of voltage detectors are designed to
supersede a variety of discrete comparator circuits and bipolar
technology voltage detectors.
These voltage detectors are especially suited for application in
battery powered systems because of their extremely low 1µA
operating current. Each part is laser programmed to the desired
trip point voltage over the range of 1.1V to 6.0V in 100mV steps.
For complete design flexibility, complementary or open-drain
output versions are available. TC54 package options include
surface mount SOT-23A and SOT-89 or through-hole TO-92
types. AN779
