Design Documentation (See the application circuit diagram.)
1. Power-supply voltage (V
IN
pin)
Since these miniature flat package products supply power to the Hall amplifier block and the control block from an
internal parallel regulator, they operate with good stability with respect to kickback currents from the motor and
variations in the power-supply voltage. They also provide an adequate ability to withstand surges. The resistor R1
between the V
CC
and V
IN
pins should be set up so that a current in the range I
CC
= 6 to 50 mA flows into the V
IN
pin
in the fan motor power-supply voltage range.
V
IN
has a typical value of 6.7 volts when I
CC
is 7 mA. The current flowing into V
IN
can be calculated with the
following formula.

Abnormal voltage considerations
The maximum allowable current for the V
IN
pin is 200 mA. Therefore, the IC design allows it to withstand voltages
up to the plus side abnormal voltage Vsurge give by formula (2).
Vsurge = V
+ R1

200 mA......(2)
2. Hall input pin voltages (IN–and IN+pins)
The Hall element output voltages to the Hall element input pins must be in the range 0 to (V
IN
–1.5 V). The gain from
the Hall input pins to the output pin is over 100 dB. The Hall input amplifier offset voltage is ±7 mV. This means that
the Hall element output must be set up taking this ±7 mV offset into account.
3. Output transistors (OUT1 and OUT2 pins)
Output current: I
O
= 1.5 A maximum
Output saturation voltage: V
O
sat = 1.15V/1.0 A (typical)
Applications should adopt one of the following three output protection techniques.
If a capacitor is inserted between OUT and ground, use a capacitor with a value up to C = 10 μF, and design that
value so that the kickback and reverse voltages do not exceed V
OR
.
If a Zener diode is added, determine a value for the Zener voltage that is lower than V
O(SUS)
. If radio-frequency
noise is a problem, insert a capacitor between B1 and B2.
If a capacitor is inserted between OUT and B1, set the capacitor value so that the kickback voltage is lower than
V
O(SUS)
. If oscillation occurs, insert a resistor in series with the capacitor.
