LV8712T: Stepping Motor Driver, Constant-Current Control, PWM

The LV8712T is a microstepping motor driver with built-in translator for easy operation. It supports full-step, half-step, quarter-step, and 1/8-step resolution. The LV8712T is optimal for driving stepping motors of scanners and small printers.

Features

Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 2W1-2 phase
Microstep can control easily by the CLK-IN input.
Output ON resistance RON = 1.1 (upper and lower total, typical, Ta = 25C )
Stand-by Current: 0uA
TSSOP24 Package
Single-channel PWM constant-current control stepping motor driver incorporated.
Power-supply voltage of motor VM max = 18V
Output current IO max = 0.8A
A thermal shutdown circuit and a low voltage detecting circuit are built into.
