power line
The power pin of the AN8267S is the Pin12. Separate it
from the power line to the moter coil. Wiring to the motor
coil should be made as thick and short as possible.
GND line
The AN8267S has two GND Pins (8 and 13). Since the
Pin8 serves as the GND pin for the coil output power transis-
tor, separate from GND of the Pin13 as much as possible.
Wiring to the Pin8 should be also as thick and short as possi-
ble.
The Pin3 is switched over in synchronization with coil cur-
rent supply/stop.
The maximum applied voltage for both Pins2 and 3 is 55V.
5. TSD (Thermal Shut Down)Pin5
The AN8267S incorporates the overheat protective circuit.
If the chip temperature of the IC reaches 150C (typ.), the
coil current stops. Since the Pin5 is a TSD circuit operation
checking pin, leave it “open” when the motor is driving nor-
mally.
7. Precautions for wiring
When mounting the AN8267S onto the PCB, pay attention
to the following points as to its wiring.
6. Hall input Pins1 and 16
Input a sine wave signal from the Hall element to the Pins1
and 16.
The input DC voltage of those pins should be 2V
min.
or
more.
It is recommended to connect the Hall element and DC
bias resistor between the Pins1 and GND.
The Hall element sine wave signal Vi to be input to the
Pins1 and 16 should be ; 15mV
