DESIGN REFERENCE
(1) VCC pin
Power supply pin for whole IC.
(2) OUT1, OUT2 pins
Single-phase coil output pins.
Bipolar forward or reverse drive output determined by OUT1 or OUT2 high. Built-in regenerative circuit that
regenerates kickback current between lower side NPN outputs if a diode is used for protection against reverse
connection.
(3) IN–, IN+ pins
Hall signal input pins
The Hall signal is amplified into a square wave by the Hall amplifier with hysteresis characteristics of ±3.5 mV
(typ.). The Hall signal amplitude should be 70 mV or more.
(4) CT pin
This pin serves timing capacitor connecting pin between CT and GND.
The capacitor determines timing of the built-in lockup protection circuit for preventing coil burnout when motor is
locked. Once normal motor rotating condition is restored, the automatic recovery circuit will reset itself.
Adjusting 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)
Connecting this pin to ground when lockup function is not used
(6) FG pin
Open-collector output pin for rotation frequency detection.
When IN– = High and IN+ = Low, then FG = Low
When IN– = Low and IN+ = High, then FG = High
(7) ST pin and HB pin
ST pin: When input to this pin is High, motor drive is stopped (OUT is high impedance).
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.
(8) Thermal protection circuit
When junction temperature TJ of IC is or over about 150℃, output current limiter is activated to protect against
damage.
