LB1960MC中文资料LB1960MC: Two-Phase Half-Wave Fan Motor Driver数据手册ONSEMI规格书

描述 Description

The LB1960MC is a 2-phase half-wave driver for fan motor. The LB1960MC is a compact package. Low external parts count, easy wiring, and small PCB area allow use also with miniature fan motors.

特性 Features

Dual power supply voltage design (5/12V) and wide voltage handling range.(3V also supported for rotation functions only)
Constant-voltage Hall bias power supply (1.3V across HB to GND) assures stable Hall output over entire temperatureand power supply voltage range. External limiting resistor not required.
Built-in Hall amplifier with hysteresis (supports core without commutating pole).
Built-in lockup protection and automatic recovery circuits (External capacitor for rotation detection need only be 0.1µF,allowing compact, cost-saving design).
Built-in output transistor with output withstand voltage 24V (max)/output current 500mA (average), 1A (peak).
Built-in thermal protection circuit.
