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)
