TI UC3903DWTR

多压监控器可调节/可选择4

Overview

The UC1903 family of quad supply and line monitor integrated circuits will respondto under- and over-voltage conditions on up to four continuously monitored voltage levels. An internal op-amp inverter allows at least one of these levels to be negative. A separate line/switcher sense input is available to provide early warning of line or other power source failures.

These parts operate over an 8-V to 40-V input supply range and require a typical stand-by current of only 7 mA.
