Overview

The LB1936V is a 2-phase bipolar drive stepper motor driver IC that supports low-voltage drive. The LB1936Vs miniature package and minimal number of external components reduces the required mounting area. It also provides high-efficiency motor drive and can reduce circuit current consumption. Since it provides a current detection pin and supports PWM control input, it can be used to implement current chopper control at the system level. The LB1936V is optimal for the stepper motor drive in scanners, digital cameras, and printers.

Features

• Low saturation voltage forward/reverse motor driver (VO sat = 0.25V at IO = 200mA)

• Two H-bridge channels

• Wide usable voltage range (Allowable voltage range : 2.5V to 9.5V, absolute maximum rating : 10.5V)

• Supports PWM input (Low power consumption can be achieved in slow delay mode that uses IN1/IN2 = H/H logic.)

• Motor (coil) current detection pin

• Built-in thermal shutdown circuit

• Miniature package (SSOP16 : 225mil)
