R3500S-Y Series
42 V Input 4ch Window Voltage Detector for Industrial Applications
No. EY-521-230523
1
The R3500S is a 4ch window voltage detector with manual reset function suited for systems requiring
functional safety. This device monitors over and under voltage from the multiple power supplies to SoCs,
memories and sensors to continuously supervise the system operating at normal voltage. This is a high-
reliability semiconductor device for industrial applications (-Y) that has passed both the screening at high
temperature and the reliability test with extended hours.
● Power supply from battery enables the voltage detector to operate independently from the power source.
● High-accuracy detection of the over and under voltages from -1.25% to 0.75% and the hysteresis of Max. 0.75%.
● Management of multiple power supplies with a single chip to save space.
● Operating Voltage Range (Max. Rating):
3.0 V to 42.0 V (50.0 V)
● Operating Temperature Range: −40°C to 125°C
● Supply Current: Typ. 10 µA
● Overvoltage Detection: 1.0 V to 5.9 V (0.01 V step)
● Undervoltage Detection:0.9 V to 5.0 V (0.01 V step)
● Detection Release Hysteresis: Max. 0.75%
(−40°C to 125°C)
● Detection Voltage Accuracy:
±0.5% (Ta = 25°C)
-1.25% to 0.75% (−40°C to 125°C)
● Detection Delay Time: Typ.20 µs
● Release Delay Time: Typ. 4 ms (C
D
= 0.01 µF)
● Output Type: Nch. Open Drain
