Power Supply Input. May be independent of fan power supply.
Fan Fault Alert, Active-Low Output. FAULT goes low to indicate a fan FAULT condition.
When FAULT occurs, the device is latched in Shutdown mode with PWM low. Toggling
the SHDN pin or cycling the V
unconditionally remain high during shutdown.
Fan Shutdown, Active-Low Input. During Shutdown mode the chip still monitors
temperature and T
Ground return for all TC652/TC653 functions.
Detect Fan Pulses Input. Pulses are detected at this pin as fan rotation chops the current
through the sense resistor, R
Over-Temperature Alert, Active-Low Output.
Ground.
PWM Fan Drive Output. Pulse width modulated rail-to-rail logic output. Nominal
Frequency is 15Hz.
OVER
is low if temperature rises above factory set point.

will release the part and fan from shutdown. FAULT will
. The absence of pulses indicates a Fan Fault.
