Power Supply Monitor

2ch Reset & Comparator IC

BD3775AF

●General Description

●Key Specifications

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.

 Input Voltage

 Voltage Detection

:VSAL

3.5V to 18V

4.20V(Typ.)

4.30V(Typ.)

1.230V(Typ.)

1.245V(Typ.)

:VSAH

:VSB

:VSC

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.

 Operating Temperature

-40℃ to 85℃

5.00mm x 6.20mm x 1.71mm

●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%).

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).
