4-Bit DAC And Voltage Monitor

The UC3910 is a complete precision reference and voltage monitor cir- cuit for Intel Pentium Pro and other high-end Microprocessor power supplies. It is designed for use in conjunction with the UC3886 PWM. The UC3910 together with the UC3886 converts 5VDC to an adjustable out- put ranging from 2.0VDC to 3.5VDC in 100mV steps with 1% DC system accuracy. The UC3910 utilizes thin film resistors to ensure high accuracy and sta- bility of its precision circuits. The chip includes a precision 5V voltage ref- erence which is capable of sourcing 10mA to external circuitry. The output voltage of the DAC is derived from this reference, and the accu- racy of the DAC reference combination is 0.5%. Programmable window Comparators monitor the supply voltage to indicate that it is within ac- ceptable limits. The window is programmed as a percentage centered around the DAC output. An overvoltage protection Comparator is set at a percentage 2 times larger than the programmed lower overvoltage level and drives an external SCR as well as provides an Open Collector output. Undervoltage lockout protection assures the correct Logic states at the outputs during power-up and power-down. By Texas Instruments
