TERMINAL FUNCTIONS NAME PIN NO. DESCRIPTION PWM-OUT 1 Digital output, open-drain. PWM output to control fan speed. TACH 2 Digital input. Fan tachometer input to measure the fan speed. Digital output, open-drain, active low. Goes low when temperature reaches the critical shutdown OVR 3 threshold or remote temperature sensor failed. (See the Interrupt section for details.) NC 4 Not connected. Reserved for manufacturer's testing. GND 5 System ground VDD 6 Power supply, +3 to +5V Digital input/output (open-drain). As an output, an active low output indicates the temperature over the THERM 7 THERM temperature limit. As an input, the pin provides an external fan control. When the pin is pulled low by external signal, the THERM-IN bit is set, and the fan is set to full-speed. FAN-FAULT 8 Digital open-drain output. Goes low when a fan failure is detected. IN– 9 Negative analog differential input. Connected to cathode of external temperature-sensing diode. Positive analog differential input. Connected to anode of external temperature-sensing diode IN+ 10 Pentium-IV™ substrate transistor or general-purpose 2N3904 type transistor. PWM mode selection. When tied low (GND), the high PWM frequency range (1kHz to 40kHz) is PWM-MODE 11 selected. When tied to VDD or floated, the low PWM frequency range (10Hz to 94Hz) is selected. Checked only on power-up or reset. Device slave address selection pin (see the SMB Interface section for details). Checked only on A1 12 power-up or reset. Device slave address selection pin (see the SMB Interface section for details). Checked only on A0 13 power-up or reset. SMBALERT 14 Digital output, open-drain, SMBALERT, active low. Requires a pull-up resistor (2.2k Ω typical). SDA 15 Bi-directional digital I/O pin, SMBus data, open-drain. Requires a pull-up resistor (2.2k Ω typical). SCLK 16 Digital input, SMBus clock. Requires a pull-up resistor (2.2k Ω typical). Copyright © 2006–2007, Texas Instruments Incorporated Submit Documentation Feedback 5 Product Folder Link(s): AMC6821 |
