Expand!Take your sets to the next level with ROHM H-bridge drivers! Ultra-low consumption Motor Drivers IC Series(H-bridge Drivers for Brush Motors.)

Overview


Realize low consumption PWM drive with ROHM's VREF-variable input system.Contributes to greater energy-savings and compactness.

ROHM offers H-bridge drivers in a variety of supply voltage, output current, and channel configurations, making them suitable for a wide variety of applications. A VREF setting function is included for ease of use and greater energy efficiency.

VREF-variable input ensures compatibility with PWM input,Low power consumption PWM drive,7V,18V,36V,3 different voltage resistances
  • Wide range of voltage resistances: 7V, 18V, 36V.
  • Low consumption PWM drive method.
  • VREF-variable input enables direct PWM drive.
  • Multiple protection circuits built in
    …Thermal shutdown, overcurrent protection, overvoltage protection, low voltage malfunction prevention.
  • 0µA standby current.

Feature 1: VREF-variable PWM drive system utilized for lower power consumption.

Unlike previous models, ROHM's new H-bridge drivers feature a VREF-variable function that enables the duty pulse to be changed for PWM drive capability, resulting in greater efficiency. A diode is also built in for surge protection.

New VREF-variable PWM Drive System(PWM Control)

Feature 2: Direct PWM control.

High speed response is achieved through circuit optimization. Conventional input pins can be used for direct PWM signal input (~100kHz), eliminating the need for additional or special terminals. In addition, the drivers support TLL input, enabling control via microcontroller.

Feature 3: Wide range of currents offered in the same package (0.5A to 2A), making replacement due to specification changes easy!
