1 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 control applications, using the following 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 minimum/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 potentiometers. 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. USER GUIDE LV88551JAGEVB LV88551RGEVB LV88561JAGEVB LV88561RGEVB LV88563JAGEVB. step 1. Connect a motor to J3 step 2. Connect PWM signal to the pin labeled PWM step 3.

Connector J3 Motor windings and signals related Hall 5. Pin PWM PWM input 6. Pin FG FG output 7. IC U1 (or U2) A dial to tweak the command PWM duty cycle for speed control 8. FETs T1 and T2 Output power FET arrays Figure 1 Connectors and key parts 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. - + Figure 2 Main power J5 is an optional connector for a power supply. Low power is assumed (less than 4A).

3 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 PIX PIZ RSA RSB PIX PIZ RSA 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.

4 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.
