Design Reference
Power supply control block motor drive. Accepts wide operation voltage range from 16.8V, 5V/12V dual power supply support. OUT1, OUT2 pins Single-phase coil output pins. Bipolar drive output with upper side inverted lower side single output. Built-in regenerative circuit regenerates kickback current between lower side outputs when diode used protection against reverse connection. IN-, pins Hall input signal pins Hall signal amplified into square wave Hall amplifier with hysteresis characteristics ±3.5mV (typ.). Hall input signal amplitude should 70mV more. This serves connecting capacitor between GND. capacitor determines characteristics built-in lockup protection circuit preventing coil burnout case motor restraint. Once normal motor load restored, automatic recovery circuit resets itself. Changing capacitance alters lockup detection time. When 0.47 capacitor connected between Lockup detection time approx. 0.5s Lockup protection time/automatic recovery time approx. 0.16s (output approx. (output OFF) When using lockup protection function, this should connected ground. (LB1862M) Open-collector output that during rotation when lockup detected. output latch type which stays also when automatic recovery circuit restored drive mode unless rotation actually resumes. (LB1962M) Open-collector output rotation frequency detection. When High Low, then When High, then High When input this High, motor drive stopped (OUT high impedance). this time, output indicates lockup protection mode OFF. Hall bias switching pin. High input, Hall bias switched reduce current drain standby mode. used, both pins should open. Thermal protection circuit When internal temperature reaches 180°C, output current limiter activated protect against damage.
