LB1633M

The LB1633M is one member of the LB1633 family which is designed as the low saturation stepping motor driver IC for use in low voltage applications. This device especially suitable for use in portable equipment such as printer, FDD, camera.

Features of the LB1633M are:(1)capable of being operated from a low voltage (2.5 V min);(2)low saturation voltage (upper Tr + lower Tr residual voltage 1.2 V max at 400 mA;(3)logic power supply and motor power supply are separate;(4)on-chip braking function;(5)on-chip spark killer diodes;(6)possible to increase the internal allowable power dissipation because the package is small-sized (MFP-16FS) and heat can be radiated easily to the outside.

The absolute maximum ratings of the LB1633M can be summarized as:(1)maximum supply voltage: -0.3 to +7.0 V;(2)output supply voltage: -0.3 to Vcc+VF V;(3)input supply voltage: -0.3 to Vcc V;(4)GND pin flow-out current: 1.0 A;(5)operating temperature: -20 to +75;(6)storage temperature: -40 to +125.
