LB11867RV Overview
.DataSheet.co.kr Ordering number : ENA1534A Monolithic Digital IC LB11867RV Overview For Fan Motor Variable Speed Single-phase Full-wave Pre-driver LB11867RV is a single-phase bipolar driving motor pre-driver with the variable speed function patible 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.
LB11867RV Key Features
- Single-phase full-wave driving pre-driver ⇒ Low-saturation drive using external PMOS-NMOS enables high-efficiency low po
- Variable speed control possible with external PWM input ⇒ Separately-excited upper direct PWM (f =30kHz) control method
- Current limiting circuit incorporated ⇒ Chopper type current limiting made at startup and during lock
- Reactive current cut circuit incorporated ⇒ Reactive current before phase changeover is cut, ensuring highly silent and
- Minimum speed setting pin ⇒ Minimum speed can be set by setting the resistance
- Soft start setting pin
- Lock protection and automatic reset circuits incorporated
- RD (lock detection) output
- Thermal shutdown circuit incorporated
