Description
Power Supply Input
No Internal Connect
Fan Shutdown, Active-low Input
1 = Fan in normal operation
0 = Fan in shutdown
Ground
No Connect
Overtemperature Alert, Active-low Output
1 = Overtemperature condition does not exist
0 = The device is in the overtemperature condition. The fan is driven at 100%.
Potential exists for system over-heating
Ground
PWM Fan Drive Output

Overtemperature Alert
May be independent of fan power supply.
Active-low output.
3.2
Fan Shutdown, Active-low Input
3.5
PWM Fan Drive Output
During Shutdown mode, the chip still monitors
temperature. T OVER is low if temperature rises above
factory set point.
Pulse width modulated rail-to-rail logic output. Nominal
frequency is 15 Hz.
3.3
Ground
Ground return for all TC650/TC651 functions.
