Microchip Technology TC647BEUA FanSpeed Controller
The TC647BEUA is a switching mode PWM fan speed controller equipped with fan restart and FanSense™ technology for fault detection. It controls the fan speed proportionally to temperature using pulse width modulation, with a thermistor connected to the VIN input providing the control voltage ranging from 1.2V to 2.6V for 0 to 100% duty cycle. The minimum fan speed is adjustable via a resistor divider on the VMIN input. An integrated Start-Up Timer ensures reliable motor startup during power-on, after shutdown, or following transient faults. Applying a logic-low to VMIN shuts down the fan. The device features FanSense™ technology, which monitors fan operation through a pulse train at the SENSE pin; if the fan stalls, opens, or disconnects, the device turns the VOUT output full on, and if the fault persists, the FAULT output is driven low. Designed for applications such as wireless systems, sensing and instrumentation, and medical devices, it supports thermistors for temperature sensing, includes fan auto-restart capabilities, and supports shutdown modes for energy-efficient systems.
