AMC6821SQDBQRQ1

Texas Instruments · Temperature Sensors · SSOP-16-150mil

AMC6821SQDBQRQ1 from Texas Instruments, in a SSOP-16-150mil. 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 PWM-OUT output Digital output, open-drain, providing the PWM output that controls fan speed.
2 TACH input Digital input for the fan tachometer, used to measure fan speed.
3 OVR output Digital output, open-drain, active low; goes low when temperature reaches the critical shutdown threshold or the remote temperature sensor has failed.
4 NC unconnected Not connected; reserved for manufacturer's testing.
5 GND power_in System ground.
6 VDD power_in Power supply input, 3 V to 5 V per the pin table; recommended operating VDD is 2.7 V to 5.5 V.
7 THERM bidirectional Open-drain I/O: as an output, active low indicates temperature over the THERM limit; as an input, pulling it low sets the THERM-IN bit and drives the fan to full speed.
8 FAN-FAULT output Digital open-drain output that goes low when a fan failure is detected.
9 IN- input Negative analog differential input, connected to the cathode of the external temperature-sensing diode.
10 IN+ input Positive analog differential input, connected to the anode of the external temperature-sensing diode (Pentium-IV substrate transistor or 2N3904-type transistor).
11 PWM-MODE input PWM frequency range select, checked only on power-up or reset: tied to GND selects the high range (1 kHz to 40 kHz); tied to VDD or floated selects the low range (10 Hz to 94 Hz).
12 A1 input Device slave address select bit, checked only on power-up or reset; tie to VDD or GND (NC allowed per the address table).
13 A0 input Device slave address select bit, checked only on power-up or reset; tie to VDD or GND (NC allowed per the address table).
14 SMBALERT output Digital open-drain output, active low; requires a pullup resistor (2.2 kΩ typical).
15 SDA bidirectional Bidirectional open-drain SMBus data pin; requires a pullup resistor (2.2 kΩ typical).
16 SCLK input SMBus clock input; requires a pullup resistor (2.2 kΩ typical).
