Function
Ground
Integrator output
Integrator input
Speed discriminator output
PLL output
Clock oscillator input. Apply the external clock signal to this pin.
Clock oscillator output. Use this pin to monitor the oscillator waveform.
Clock divider selector input
High: 1/8, Middle or Open: 1/32, and Low: 1/16.
Chip enable input
High or Open: stop, Low: drive on.
PWM carrier oscillator. An external capacitor to charge and discharge, and an
external resistor must be provided.
5 V fixed voltage output. Always output regardless of the state of the CE input.
An external capacitor sets the time until the stuck rotor protection circuit
operates. If this pin is shorted to ground, the protection circuit will not operate.
After the stuck rotor protection circuit operates, the IC can be reset by turning the
power off and then on again, or switching CE from low to high.
FG amplifier – input.
FG amplifier + input. This pin is used for temperature monitoring. See the
reference data.
The w+ and v– Hall amplifier input
The v+, u– Hall amplifier input
The u+, w– Hall amplifier input
Speed monitor output. Outputs a low level during fixed speed drive. This is an
open collector output.
Power supply
W-phase output
V-phase output
U-phase output
Current detector. Connect a current detection resistor to this pin.
