Evaluation Board for
Motor Driver, Single-phase, PWM,
Full-wave, BLDC Motor
Overview
This evaluation board is designed to provide an easy and quick development
platform for single-phase BLDC motor control applications, using the fol-
lowing devices.
LV88551, LV88561, LV88563
These devices have the closed loop controller for motor rotation speed. And,
potentiometers are provided on this board to configure the mini-
mum/maximum target speed, the speed curve against the input PWM duty
cycle, and some other parameters/options. The potentiometers might be useful
for tuning these parameters and options, otherwise fixed resistors must be
removed and re-soldered.
Setting with fixed resistors is also applicable by disconnecting the potenti-
ometers.
Quick start
The evaluation board is programmed to work standalone without PC. The
following operation allows the operation of most motors with the default
parameters that are preloaded into the device.
step 1. Connect a motor to J3
step 2. Connect PWM signal to the pin labeled ‘PWM’
step 3. Connect a power supply to J4 (J5 is provided optionally for low
power application less than 4A).
step 4. Turn on power supply

Power supply
J4 is the main power supply connector. The outputs of a
power supplier will be connected to this connector. For
LV88551EVB, the POWER pin voltage accepts up to
18V. However, for LV88561EVB and LV88563EVB,
POWER pin for the operation is from 24V to 48V.

J5 is an optional connector for a power supply. Low
power is assumed (less than 4A).

Hall sensor or Hall IC
These devices need a Hall sensor or Hall IC to detect the
commutation timing. IN1 and IN2 pins are Hall signal
input pins. This EVB has Hall sensor and in this case,
the resistor R38-R40 should be “OPEN”. However, in
case of using Hall IC, they should be 10kohm.
Parameter setting
This EVB can use for evaluation at stand-alone state.
The AD converter parameters (assigned to the pins;
RSA, RSB, PIX, PIZ, LAI, LAG, SFS), can be set by
either analog potentiometers or register dividers.
The following table shows resistor and jumper setting
combination.

TYPICAL OPERATION
Overall tuning procedure
1. setup fan, power supply, pulse generator (for PWM
duty cycle input)
2. set setting pin voltage with either potentiometer or
resistor pair
3. Turn-on power supply
4. Evaluate motor
5. Repeat from step 2, until appropriate evaluation
result obtained
The configuration is loaded right after power-on from
off. Therefore, power off/on cycle is required every
time the parameters are changed.
Waveform example
Below is the example waveform of LV88561JA with
various Lead Angle Settings.
The EVB condition is;
VIN=48V
2000RPM setting (PWM=100%)
Lead Angle setting (LAG ; 0 deg., LAI ; 0 deg.
Lead Angle setting (LAG ; +9.975deg., LAI ; 0 deg.
