Texas Instruments UC1903 Quad Supply and Line Monitor 5962-88697012A

The 5962-88697012A is a quad supply and line monitor integrated circuit designed for power management applications. It can monitor up to four separate supply voltage levels, responding to both under-voltage and over-voltage conditions. The device features an internal op-amp inverter, allowing for the monitoring of negative voltage levels. It includes a line/switcher sense input for early warning of power source failures and has programmable under-voltage and over-voltage thresholds with proportional hysteresis for precise operation. The device operates over a supply voltage range of 8V to 40V and has a typical standby current of 7 mA. It provides three open-collector outputs capable of sinking over 30 mA, indicating fault conditions such as under-voltage, over-voltage, and a "power OK" status. Additionally, it includes a general-purpose op-amp for auxiliary functions, capable of sourcing 20 mA of output current. The 5962-88697012A is suitable for applications requiring reliable voltage monitoring and fault indication in power management systems.
