LB11967V - Bariable Speed Single-Phase Full Wave Pre-Driver

Features

  • Pre-driver for single-phase full-wave drive ⇒ PNP-EMOS is used as an external power TR, enabling high-efficiency low-consumption drive by means of the low-saturation output and single-phase full-wave drive. (PMOS-NMOS also applicable).
  • External PWM input enabling variable speed control ⇒ Separately-excited upper direct PWM (f = 25kHz) control method, enabling highly silent speed control.
  • Compatible with 12V, 24V, and 48V power supplies.
  • Current limiter circui.

Ordering number : ENN8362 Monolithic Linear IC LB11967V Overview Bariable Speed Single-Phase Full-Wave Pre-Driver For Fan Motor The LB11967V is a single-phase bipolar variable speed fan motor predriver that works with an external PWM signal. A highly efficient, quiet and low power consumption motor driver circuit, with a large variable speed, can be implemented by adding a small number of external components. This device is optimal for driving large scale fan motors (with large air volume and large current) such as those used in servers and consumer products.
