Pin Assignments
Pin Functions
Pin No.
Pin name
Function
1
2
IN−
IN+
Input pins for hall element outputs.
Common-mode input voltage range is 0 to VIN−1.5 V, offset voltage is ±7 mV
3
C
Capacitor pin (1 to 10 µF) that forms automatic return circuit.
When rotation is stopped due to overload, the pin voltage increases and output stops.
After proper load adjustment, the output returns from ‘‘stop’’ mode to ‘‘drive’’ mode automatically.
The lock detect time can be set by changing the capacitor constant.
4
6
OUT1
OUT2
Output pins. The output transistor is Darlington connected.
Connect either an external capacitor or an external Zener diode for output transistor protection.
5
GND
Ground pin.
8
7
B1
B2
Base pins for Darlington connected output transistors.
If radio noise is a problem, add a capacitor (0.01 to 0.1 µF).
9
RD
Open collector output. Drive mode: ‘‘L’’, Stop mode: ‘‘H’’
10
VIN
Insert a limiting resistor between VCC and VIN and use the voltage applied between VIN and ground in a
range from 3.8 to 6.0 V.
In this case, the current consumption ICC at the VIN pin is 1.4 to 3.7 mA (when VIN = 4.3 V).
