BD3775AF
●General Description BD3775AF is designed to monitor the voltage level of one or two power supplies (+5V and an arbitrary voltage) in a microprocessor circuit, memory board in large-size computer, for example. If the circuit’s power supply deviates more than a specified amount, then the BD3775AF generates a reset signal to the microprocessor. Also, the BD3775AF has a comparator for the over voltage protection and the high-precision reference voltage and so on apart from the above features. It is also available for more complex applications so.
●Feature ■ High precision voltage detection (VSA = 4.20V ± 2.5%). ■ Internal reset circuit that user selectable threshold level with hysteresis (VSB = 1.230V ± 1.5%).
