The UC1903J from Texas Instruments is a versatile Quad Supply and Line Monitor integrated circuit. It is designed to continuously monitor up to four separate voltage levels, with the capability to sense negative supply voltages via an internal inverter.
Key electrical features include a supply voltage range of 8V to 40V, a typical standby current of 7mA, and a precision 2.5V reference. The device offers programmable under- and over-voltage fault thresholds with proportional hysteresis. It provides three high-current, open-collector outputs to indicate over-voltage, under-voltage, and power-OK conditions.
This IC operates within a wide temperature range of -55°C to 125°C. It is housed in a 18-pin CDIP package suitable for through-hole mounting. The package dimensions are 23.1mm in length, 6.92mm in width, with a pitch of 2.54mm.
The UC1903J is suitable for applications requiring robust power supply monitoring and fault detection.
