ADT7461ARMZ-R7

onsemi · Temperature Sensors · MSOP-8

ADT7461ARMZ-R7 from onsemi, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD power_in Positive supply, 3.0 V to 5.5 V; absolute maximum VDD to GND is −0.3 V to +5.5 V.
2 D+ passive Positive connection to the remote temperature sensor (diode); absolute range is −0.3 V to VDD + 0.3 V.
3 D− passive Negative connection to the remote temperature sensor (diode); absolute range to GND is −0.3 V to +0.6 V.
4 THERM output Open-drain overtemperature output used to turn a fan on/off or throttle a CPU clock; requires a pullup to VDD and is rated −0.3 V to VDD + 0.3 V, with input current limit −1 to +50 mA.
5 GND power_in Supply ground connection.
6 ALERT/THERM2 output Open-drain logic output used as interrupt or SMBus Alert, also configurable as a second THERM output; requires a pullup resistor and is rated −0.3 V to +5.5 V.
7 SDATA bidirectional SMBus serial data line, open-drain output; requires a pullup resistor and is rated −0.3 V to +5.5 V.
8 SCLK input SMBus serial clock logic input; requires a pullup resistor and is rated −0.3 V to +5.5 V.
