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 (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)
Monolithic Digital IC
1-2 Phase Excitation
Stepping Motor Driver
Ordering number : EN7231
