[Design Specifications]
(1) Supply voltage
The hall amp and control block of the LB1660 series are supplied with power from the on-chip parallel regulator. Set the DC
resistance R1 across V
CC
and V
IN
so that I
CC
flowing into the V
IN
pin becomes 7 to 50 mA in the supply voltage range of a
fan motor.
V
IN
is 6.7 V typ at I
CC
= 7 mA.
The current flowing into V

is calculated using the equation shown below.

Consideration given to surge voltage
The maximum allowable current at V
IN
pin is 200 mA. Therefore, the design is made so that a surge voltage of positive value
calculated using the following equation is allowable in applications where the IC is used.

(2) Hall input offset voltage
The gain in transmission from the hall input pin to the output pin is 100 dB or greater. The offset voltage of the hall input
amp is
±
7 mV; therefore, the hall element output must be set with the offset voltage (
±
7 mV) considered.
(3) Output transistor
Output Current
Output saturation voltage
When external capacitors are connected to the output stages, the capacitance should not exceed 10 μF. Since the LB1660N,
1664N have a protect zener diode across collector and base, the kickback voltage induced by the coil is cut at V
