Internal open collector output comparators to create Over Voltage Detection circuit, reference voltage generator, and more. (VSC,OUTC), User selectable delay time of releasing reset signal depending on capacitor of CT node., Low power dissipation (Icc = 0.35mA ,VCC = 5V)., SOP8 package (5.0×6.2mm, 1.27mm pitch).

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.
