Keep the pins open when unused. *6 The current limiter is activated when the current detection resistor voltage exceeds 250mV between RF and VCC. Where RL=0.5Ω, current limiter is activated at Io=500mA. Setting is made using Rf resistance. *7 Hall element outputs stable hall signal with good temperature characteristic when it is biased with constant voltage from HB pin. If you wish to alleviate heating of IC, do not use HB pin. When you do not use this Pin (Pin HB) , pull down with resistor of around 10kΩ(recommended). To defend signal against the noise, it is necessary to wire as short as possible from hall sensor to each pin and to connect the capacitor between IN1 and IN2. Value from 1,000pF to 10,000pF is recommended for the capacitor. But its value should be selected in consideration with the actual motor action. www.onsemi.com 8 LV8862JA Adjustment of soft-switching width LV8862JA soft-switching wide select 12PIN RGL OUT1 Wide 13PIN SSW Connect OUT2 1,16PIN GND 12PIN RGL Medium OUT1 13PIN SSW OPEN OUT2 1,16PIN GND OUT1 12PIN RGL Connect Narrow 13PIN SSW OUT2 1,16PIN GND phase switch LV8862JA realizes high efficiency and low noise by controlling reactive power using soft switch before and after phase switch by variable PWM-duty. The width of soft switch before and after switching is controlled by SSW pin voltage. Therefore, it is adjustable by connecting to SSW and RGL or GND or open. . When the motor rotation speed is very high, there is possibility to show unstable soft-switching waveform. www.onsemi.com 9 LV8862JA Description of operation PWM speed control waveform PWM 100% OUT 0% Low Speed Stop High Speed PWM Control Variable Speed FG www.onsemi.com 10 Full Speed LV8862JA Lock protection operation waveform Stand-by mode operation waveform www.onsemi.com 11 LV8862JA ORDERING INFORMATION Device LV8862JA-AH Package SSOP16 (225mil) (Pb-Free / Halogen Free) Shipping (Qty / Packing) 2000 / Tape & Reel ON Semiconductor and the ON logo are registered trademarks of Semiconductor Components Industries, LLC (SCILLC) or its subsidiaries in the United States and/or other countries.
