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 VCC and VIN so that ICC flowing into the VIN pin becomes 7 to 50mA in the supply
voltage range of a fan motor.
VIN is 6.7V typ at ICC = 7mA.
The current flowing into VIN is calculated using the equation shown below.
ICC =
VCC - VIN
R1

Consideration given to surge voltage
The maximum allowable current at VIN pin is 200mA. 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.
Vsurge = VIN + R1 × 200mA (2)
(2) Hall input offset voltage
The gain in transmission from the hall input pin to the output pin is 100dB or greater. The offset voltage of the hall
input amp is
±7mV ; therefore, the hall element output must be set with the offset voltage (±7mV) considered.
(3) Output transistor
Output Current
IO = 1.5A max
Output saturation voltage
VOsat = 2.0V/1.5A
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 VOLM = 59V typ.
(4) Lock detect threshold voltage
The LB1660 series have the function to stop the output drive after the lapse of a given period of time when a motor is
locked, and period of time can be set by C, R3.
The CR pin peripheral equivalent circuit is shown below. The LB1660 series generate the CR pin discharge pulse
when the phase changes, (detection of rotation). When a motor is locked (very low rotational speed), the C connected
to the CR pin stops discharging and the CR pin voltage rises. When the CR pin voltage exceeds the threshold voltage
(VIN × 0.8), the output drive current becomes zero and the output transistor is turned off, and the RD pin output turns
from “L” to “H”. The RD pin output is of the open collector type.
