LB11660RV Description
.DataSheet.co.kr Ordering number : ENA0082 LB11660RV Overview Monolithic Digital IC Single-Phase Full-Wave Driver For Fan Motor 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.
LB11660RV Key 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, l
- Lowest speed setting possible
- Current limiter circuit (the circuit actuated at IO = 1A when Rf = 0.5Ω, Rf determines the limiter value.)
- Soft switching circuit achieves low power consumption, low loss, and low noise driving at a time of phase change
- Lock protection and automatic reset functions incorporated (including a circuit that changes the ON/OFF ratio according
- RD (lock detection) output
- Thermal protection circuit incorporated (design guaranteed)
