Monolithic Digital IC

1-2 Phase Excitation

Stepping Motor Driver

LB1937T

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 LB1937T's 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 (V sat = 0.3V at I = 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)
