LB11660RV

LB11660RV Monolithic Digital IC Half-pre Motor Driver Single-Phase Full-Wave Drive, for Fan Motor Overview The LB11660RV is a single-phase bipolar half pre-driver that can achieve high-efficient direct PWM drive with ease. It is ideal for driving small-sized cooling fans used in servers. The LB11660RV is provided with the RD (lock detection) output pin and the LB11660FV the FG (rotational speed detection) output pin, respectively. Features Single-phase full-wave drive (15V-1.5A output transistor built in) upper output Tr incorporated half pre-driver. Variable speed control by an external signal. Separately-excited upper TR direct PWM control method, enabling silent, low-vibration variable speed control. Lowest speed setting possible. Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5, Rf determines the limiter value.) Kickback absorption circuit built in. Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change. HB built in. Lock protection and automatic reset functions incorporated (including a circuit that changes the ON/OFF ratio according to the power supply voltage). RD (lock detection) output. Thermal protection circuit incorporated (design guaranteed). www.onsemi.com SSOP16 (225mil) ORDERING INFORMATION See detailed ordering and shipping information on page 9 of this data sheet. © Semiconductor Components Industries, LLC, 2015 August 2015 - Rev. 1 1 Publication Order ...
