The Texas Instruments UC1903L883B is a quad supply and line monitor integrated circuit. It is designed to respond to under- and over-voltage conditions on up to four continuously monitored voltage levels.
Key electrical specifications include the ability to monitor four supplies with adjustable threshold voltages, typically 1.8V and 2.5V. The device operates over a wide input voltage range of 8V to 40V with a low standby current of 7mA. It features an active-low, open-drain reset output and a precision 2.5V reference.
This IC includes features such as negative voltage monitoring, an internal inverter for sensing negative supply voltages, and a line/switch sense input for early power source failure warning. Programmable under- and over-voltage fault thresholds with proportional hysteresis are also included. A general-purpose op-amp is available for auxiliary use.
The UC1903L883B is available in LCCC (FK) and CDIP (J) packages, suitable for surface mount applications. It operates within a wide temperature range of -55°C to 125°C, making it suitable for demanding environments.
