  • Built-in lockup protection and automatic recovery circuits
  • Latch-type lockup detection output (RD) is Low during rotation and High during stop
  • Hall bias pin and start/stop pin allow reduced current drain in standby mode
  • Built-in thermal protection circuit Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings Unit Maximum supply voltage V CC max 17 V Maximum output current I OUT max 0.5 A Maximum output withstand voltage V OUT max 17 V RD maximum output withstand voltage V RD max 17 V RD maximum output current I RD max 5m A HB maximum output current I B max 10 mA ST maximum input voltage V ST max 15 V Allowable power dissipation Pd max Mounted on a specified board * 850 mW Operating temperature Topr -30 to +90 °C Storage temperature Tstg -55 to +150 °C * Specified board: 114.3mm × 76.2mm × 1.5mm, glass epoxy board. Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current, high voltage, or drastic temperature change, the reliability of the IC may be degraded.

PS No.A2024-5/7 Design Reference (1) VCC pin Power supply pin for control block and motor drive. Accepts a wide operation voltage range from 3.8 to 16.8V, for 5V/12V dual power supply support. (2) OUT1, OUT2 pins Single-phase coil output pins. Bipolar drive output with upper side inverted and lower side single output. Built-in regenerative circuit regenerates kickback current between lower side NPN outputs when a diode is used for protection against reverse connection. (3) IN−, IN+ pins Hall input signal pins The Hall signal is amplified into a square wave by the Hall amplifier with hysteresis characteristics of ±3.5mV (typ.). The Hall input signal amplitude should be 70mV or more. (4) CT pin This pin serves for connecting a capacitor between CT and GND. The capacitor determines the characteristics of the built-in lockup protection circuit for preventing coil burnout in the case of motor restraint. Once normal motor load is restored, the automatic recovery circuit resets itself. Changing the capacitance alters the lockup detection time. When a 0.47 mF capacitor is connected between CT and GND Lockup detection time : approx. 0.5s Lockup protection time/automatic recovery time : approx. 0.16s (output ON) approx. 1s (output OFF) When not using lockup protection function, this pin should be connected to ground. (5) RD pin Open-collector output pin that is Low during rotation and OFF when lockup is detected. The output is a latch type which stays OFF also when the automatic recovery circuit has restored drive mode unless the rotation actually resumes. (6) ST pin and HB pin ST pin : When input to this pin is High, motor drive is stopped (OUT is high impedance). At this time, RD output indicates lockup protection mode OFF. HB pin : Hall bias switching pin. At ST pin High input, Hall bias is switched to reduce current drain in fan standby mode. If not used, both pins should be open. (7) Thermal protection circuit When internal temperature Tj of IC reaches 180°C, output current limiter is activated to protect against damage.
