New Stepping Motor Drivers

ROHM has recently completed the development several new Stepping Motor Drivers featuring low power consumption for high-efficiency motor driving. They are ideally suited for a wide variety of applications, including industrial equipment, PC peripheral devices, office (OA) equipment, and home electrical appliances. The complete line-up can be seen from the table below.

Samples and evaluation boards are available on request.

Features

- Full Line-up, High Performance, High Reliability
- Bipolar PWM constant-current drive
- Small & Thin Power Package
- Power DMOS technology
- Single Power Supply
             - No logic power supply needed, few external components required
               (no bypass capacitor needed)
             - Simplifies power-up/down sequence
             - Simplifies PCB layout and routing
- Ghost Supply Prevention (G.S.P.)
             - Prevents malfunctions in motor driver IC or any other IC on the
               same Vcc line
             - Simplifies power-up/down sequence
- Linearly variable fast/slow decay ration
- OCP – Over-Current Protection
- No Charge Pump Required
             - Less external components
               (eliminates 2+ high- voltage electrolytic caps)
             - High failure resistance
             - Reduced EMI
- High ESD Resistance (HBM/MM = 4000 V / 400V)
