LB1960MC

Overview

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.

Functions

• 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 temperature

and 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.

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.
