LV8736LF PWM Current Control Stepping Motor Driver

www.DataSheet.co.kr Ordering number : ENA1987 LV8736LF Overview Bi-CMOS LSI PWM Constant-Current Control Stepping Motor Driver The LV8736LF is a 2-channel H-bridge driver IC that can switch a stepping motor driver, which is capable of micro-step drive and supports 2W 1-2 phase excitation, and two channels of a brushed motor driver, which supports forwar.

Features

• Single-channel PWM current control stepping motor driver (selectable with DC motor driver channel 2) incorporated.
• BiCDMOS process IC
• Low on resistance (upper side : 0.75Ω ; lower side : 0.5Ω ; total of upper and lower : 1.25Ω ; Ta = 25°C, IO = 1A)
• Excitation mode can be set to 2-phase, 1-2 phase, W1-2 phase , or 2W1-2 phase
• Excitation step proceeds only by step signal input
• Motor current selectable in four steps
• Output short-circuit protection circuit (selectable from latch-type or auto-reset-type) incorporated
• Unusual condition warning output pins
• Built-in thermal shutdown .
