Description
Overview
The LB1937T is a 2-phase bipolar drive stepping motor driver IC that supports low-voltage drive and can drive two stepping motors at the same time.
The LB1937Ts 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 LB1937T is optimal for the stepping motors used for lens drive in digital cameras, printers, and movie cameras.Functions and
Features
• Low saturation voltage forward/reverse motor driver (VO sat = 0.3V at IO = 200mA)
• Four 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
• Thin form factor miniature package (TSSOP24)
Alternatives

Functional Equivalent (FE) materials, including Fused Filament Fabrication (FFF) form, assembly, and functionally compatible substitute materials.
