NJU7360
Single-phase DC Brushless Motor Driver IC
■ GENERAL DESCRIPTION
■ PACKAGE OUTLINE
The NJU7360 is a single-phase DC brushless motor driver
IC designed for small and high power fan-motor applications.
It provides a low operating current of 2mA (typ.) and low
saturation output voltage at high output current operation,
which offers a high efficiency motor driving. It also has a high
output current capability of 1000mA (peak) and 400mA
(continuous). The NJU7360 has a hall bias circuit and hall
signal amplifier for output wave optimization, which offers a low
noise motor driving. It also has useful functions such as a FG
(frequency generator) output for speed detection and thermal
shutdown. The NJU7360 is available in a small and thin
package of MSOP8 (TVSP8), which provides downsizing and
thinning in motor applications.

[Design Notes]
Above application example is designed for 5V operation with motor current of 250mA. It uses the following
components:
Hall elements: HW101A (AKE)
1. Selection of C1 and D1:
C1 is used for a noise reduction purpose. A typical value is 0.1uF.
Optimize the value in actual operating conditions if necessary. D1 is a diode for protection against reverse voltage
supply. Silicon rectifier diode (WO3C, 10D1 and equivalent) is appropriate.
2. Position Detection Circuit Hall Device
2-1. When using HB (R1 design)
By connecting a Hall device to the Hall bias terminal (HB), a constant Hall output amplitude that has good
temperature characteristics is obtained, resulting in stable linear drive. If it is necessary to adjust the Hall output
amplitude, perform adjustment with R1.
2-2. When using VDD (R2 and R3 design)
When it is necessary to increase the Hall bias current to increase the Hall output amplitude, obtain Hall bias from VDD.
The input bias voltage for the amplifier must be used within the Hall input common mode voltage (0.4 - VDD-1 V)
including the amplitude of the signal. It is recommended that the Hall bias voltage be one half of the power supply
voltage, that is, VDD/2.

3. Design of FG output resistance (RL)
FG Out (FG: Pin5) is an open drain output and RL is a pull up register. A typical value of RL is 10kΩ.
The timing chart of FG Out is as follows.
Note that the pull up resistance shall be connected to below supply voltage.
