S42WD61PAS

The S42WD61PAS is designed as a precision power supervisory circuit. It automatically monitors the device's Vcc level and will generate reset output on two complementary open drain outputs. In addition to the Vcc monitoring, it also provides a second voltage comparator input. This input has an independent open drain output that can be wire-OR'ed with the RESET I/O or it can be used as a system interrupt.

S42WD61PAS has six features. (1)Precision dual voltage monitor. (2)Second voltage monitor output. (3)Watchdog timer. (4)Memory internally organized 2x8. (5)Extended programmable functions available on SMS24. (6)High reliability. Those are all the main features.

Some absolute maximum ratings of S42WD61PAS have been concluded into several points as follow. (1)Its temperature under bias would be from -40°C to 85°C. (2)Its storage temperature range would be from -65°C to 125°C. (3)Its soldering temperature less than 10 seconds would be 300°C. (4)Its supply voltage would be from 0V to 6.5V. (5)Its voltage on any pin would be from -0.3V to Vcc+0.3V. (6)Its ESD voltage JEDEC method would be 2000V. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of S42WD61PAS are concluded as follow. (1)Its supply current CMOS with SCL=SDA=Vcc and all other inputs=GND would be max 50uA at Vcc=5.5V and would be max 25uA at Vcc=3.3V. (2)Its input leakage would be max 10uA. (3)Its output leakage would be max 10uA. (4)Its input low voltage would be max 0.3Vcc. (5)Its input high voltage would be max 0.7Vcc. (6)Its output low voltage would be max 0.4V. (7)Its SCL clock frequency would be max 100KHz from 2.7V to 4.5V and would be max 400KHz from 4.5V to 5.5V. (8)Its bus free time would be min 4.7us from 2.7V to 4.5V and would be min 1.3us from 4.5V to 5.5V. And so on.
