SKHWAC Price| PIN | NAME | FUNCTION | | 1 | GND | Ground | | 2 | FORCEON | Force Fan On Input. Set FORCEON low to force the fan switch on. Set FORCEON high for normal operation. | | 3 | HYST | Three-State Hysteresis Input. Connect HYST to VDD for 80C, GND for 40C, and leave HYST unconnected for loC hysteresis. | | 4 | FANON | Fan-On Indicator Output. Push-pull output. FANON is high when the fan switch is on. FANON is low when the fan switch is off. | | 5 | OT | Overtemperature Output. Active-Iow when the temperature is 300C above the fan threshold. Open- drain output, requires resistive pullup. | | 6 | WARN | Overtemperature Warning Output. Active-Iow when the temperature is 150C above the fan threshold. Open-drain output, requires resistive pullup. | | 7 | VDD | Supply Voltage. Bypass with a lUF capacitor to GND as close to VDD pin as possible. | | 8 | FANOUT | Fan-Switch (Driver) Output. Connect to the low side of a fan. | | Exposed Paddle | GND | Ground | | | |
