LB11868V

Ordering number : ENA1915A LB11868V Monolithic Digital IC For Fan Motor Variable Speed Single-phase Full-wave Pre-driver http://onsemi.com Overview LB11868V is a single-phase bipolar driving motor pre-driver with the variable speed function compatible with external PWM signal. With a few external parts, a highly-efficient and highly-silent variable drive fan motor with low power consumption can be achieved. This product is best suited for driving of the server requiring large air flow and large current and the fan motor of consumer appliances. Features Single-phase full-wave driving pre-driver Variable speed control possible with external PWM input Current limiting circuit incorporated Reactive current cut circuit incorporated Minimum speed setting pin Soft start setting pin Start setting pin of on time Pch-FET kickback absorption setting pin Lock protection and automatic reset circuits incorporated FG (rotational speed detection) output, RD (lock detection) output Thermal shutdown circuit incorporated Semiconductor Components Industries, LLC, 2013 May, 2013 51311 SY/11911 SY 20101217-S00010 No.A1915-1/11 LB11868V Specifications Absolute Maximum Ratings at Ta = 25°C Parameter Symbol Conditions Ratings VCC pin maximum supply voltage OUTN pin maximum current OUTN pin output withstand voltage OUTP pin maximum Sink current Maximum inflow current at OUTP pin OFF VCC max IOUTN max VOUTN max IOUTP max IOUTP off max DUTY8% under OUTP pin output wi...
