Product Summary

The LB1649 is a dual bidirectional motor driver. Since each channel has a 2-input logic circuit and performs bidirectional driving and braking functions, it is capable of direct driving 2pcs. of motor of various types rated at 6 to 24V. It is especially suited for dual motor drive (reel motor, loading motor, cassette motor in VCR) and for stepping motor drive.

Parametrics

LB1649 absolute maximum ratings: (1)Maximum supply voltage: 25 V; (2)Input voltage: 25V; (3)Output current: ±1 A; (4)Allowable power dissipation: 1.9 W; (5)Operating temperature: –25 to +75°C; (6)Storage temperature: –55 to +125°C.

Features
