Overview
LV8860V is a driver IC used for single-phase fan motor. High-efficiency and low-noise are realized by reducing reactive power using Silent PWM. The operating range of LV8860V is wide. LV8860V also corresponds to 24V. Therefore, it is optimal for office automation equipment and factory automation equipment.
Functions
• Single-phase full wave operation by Silent PWM drive. • Speed is controllable by PWM input. • Hall bias output pin. • Integrated Quick Start Circuit. • FG (rotation detection) / RD (lock detection) output pin (open drain output) • Integrated current limiter circuit (limit at IO=450mA with Rf=0.5Ω connection, limit value is determined based on
Rf.)
• Integrated lock protector circuit and automatic recovery circuit. • Integrated thermal shut-down (TSD) circuit.

Caution 1) Absolute maximum ratings represent the value which cannot be exceeded for any length of time. Caution 2) Even when the device is used within the range of absolute maximum ratings, as a result of continuous usage under high temperature, high current,
high voltage, or drastic temperature change, the reliability of the IC may be degraded. Please contact us for the further details.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability.
