Pin Function
Pin No. 27 28 1 4 5 Pin Name UOUT VOUT WOUT Rf (SENSE) Rf (PWR) Function U phase output, Spark killer diodes are built-in. V phase output, Spark killer diodes are built-in. W phase output, Spark killer diodes are built-in. Output current detection. The control block current limiter operates using the resistor Rf connected between these pins and ground. Also, the lower side saturation prevention circuit and the torque ripple correction circuit operate based on the voltages across this resistor. It is especially important to note that, since the saturation prevention level is set using this voltage, the lower side saturation prevention circuit will become less effective in the high current region if the value of Rf is lowered excessively. Also, the PWR and SENSE pins must be connected together. 22 5 VS GSENSE Output block power supply Ground sensing. The influence of the common ground impedance on Rf can be excluded by connecting this pin to nearest ground for the Rf resistor side of the motor ground wiring that includes Rf. (This pin must not be left open.) 6 FR Forward / reverse selection. The voltage applied to this pin selects the motor direction (forward or reverse). (Vth=2.5V at VCC=5V (typical)) 23 ADJ Used for external adjustment of the torque ripple correction ratio. Apply a voltage externally with a low-impedance circuit to the ADJ pin to adjust the correction ratio. The correction ratio falls as the applied voltage is increased, and increases as the applied voltage decreases. The torque ripple correction ratio can be modified by factors in the range 0 to 2 times the ratio that applies when his pin is left open. (The pin voltage is set to about VCC / 2 internally, and the input impedance is about 5k.) 7 GND Ground for all circuits other than the output transistors. The lowest potential of the output transistors is that of the Rf pin. 8 FGINInput used when the FG amplifier is used as an inverting input. A feedback resistor must be connected between FGOUT and this pin.

Note: In the FR column, "H" refers to a voltage of 2.75V or higher, and "L" refers to 2.25V or lower (when VCC=5V.) Note: In the Hall input column, "H" refers to the state in the corresponding phase where the +input is at a potential at least 0.01V higher than the -input, and "L" refers to the state where the -input is at a potential at least 0.01V higher than the +input.
Note: Since the drive technique adopted is a 180 technique, phases other than the sink and source phase do not turn off.
