LB1630

The LB1630 is a low-saturation bidirectional motor driver IC for use in low-voltage applications. It is especially suited for in small sized low-voltage motor for printers, cassette tape recorders, and consumer equipment.

The LB1630 has the following features:(1)capable of operating from a low voltage(2.5V min).low current dissipation at the standy mode(ICC30uA);(2)low-saturation voltage(upper transistor+lower transistor residual voltage 1.2V max at 400mA);(3)on-chip spark killer diodes.

LB1630 also has some absolute maximum ratings (Ta is 25) and electrical characteristics(Ta is 25).absolute maximum ratings:(1)maximum power supply voltage is -0.3 v to 7 V;(2)output supply voltage is -0.3V to VCC+VF V;(3)input sup ply voltage is -0.3V to 7.0V;(4):GND pin flow-out current is 2 A when pulse width is 50ms and duty is 10%;(5):allow able power dissipation is 785 mW;(6):operating temperature is -20 to 75;storage temperature is -40 to +125 ;(7):allowable load resistance is 3 ohm when pulse width is less than 50ms,and duty is 10%. electrical characteri stics:(1):output saturation voltage(VOUT1)is 0.6V max when VCC is 3V,VIN is 3V and IOUT is 200mA;output saturat ion voltage(VOUT2)is 1.2V max when VCC is 3.5V,VIN is 3V and IOUT is 400mA;(2):output sustain voltage is 9 V min when IOUt is 400mA;(3):output leakage current is 1.0mA max when VCC is 6V;(4)input current is 1.0mA max when VIN is 6V;(5):spark killer diode: reverse current is 30uA max when VCC is 6V and VIN is 0V;forward voltage is 1.7 V max when IOUT is 500mA;(6):current dissipation is 430 mA max when ICC is 3.5 V,VIN and 3V and IOUT is 400mA.
