说明

  • PWM Locked-Rotor Detection Application Circuit with Sleep Mode Support. This section presents a fan monitoring circuit that can be used in conventional MIC502-based circuits employing pulse-width modulation (PWM) fan speed control. The circuit relies on detecting motor commutation to indicate fan operation and does not require a three wire fan with a tachometer output
