H-bridge Drivers from ROH Semiconductor DC brush motors are simple, reliable and lowcost. And now, to achieve the best possible performance and design flexibility, ROH offers a complete line of H-bridge drivers for DC brush motors that combine a selection of analog and digital input control strategies with advanced, high-efficiency PW motor speed control output. These powerful new ICs provide a unique V REF to PW that can quickly transform an exisitng analog speed control design into a highperformance, low power PW configuration - sometimes by simply replacing the IC! Inputs are also provided for direct digital (PW) control from an external CU or other motor control device. ROH H-bridge ICs combine BiCOS control and power OSFET outputs to deliver exceptional performance with minimal external components, virtually zero standby current and high operating efficiency. Fully integrated protection is also provided, including: Internal shoot through protection ESD protection fault protection (current, voltage, temp) The ROH H-bridge drive product line is offered with pin-compatible devices optimized for 7 V, 18 V and 36 V maximum supply voltages to optimize power consumption; and in single and dual channel configurations. These latest ROH H-bridge ICs are pincompatible with earlier (linear output) models making it possble to migrate to PW control without any modifications to the PCB layout. input control Input Output H L Forward L H Reverse L L Brake H H Idle Direct PW control Input Output PW L Forward L PW L L H H Reverse Brake Idle Analog and Digital Control Inputs Analog control () inputs combined with digital control inputs and provide exceptional flexibilty in controlling motor speed and direction. The and also provide a TTL-compatible interface to an CU or other external PW control device. High efficiency drive COS output ROH s P-Channel / N-Channel high-power COS output provides low on resistance and also eliminates the need for a charge pump and additional external components required to drive the N-Channel high-side switch common in other H-bridge drivers. Enhanced Protection Circuitry Built-in protection s such as (thermal shut down), (overcurrent protection), (overvoltage protection), and (undervoltage lock out) assure system reliability. PW output improves motor control and response Whether operated via an external CU or with the ICs internal V REF to PW ry, motor speed and position are accurately and efficiently controlled.

Counter rotating symmetrical pin layout max. max. max. 18 33 Products Voltage-controlled PW system Basic voltage control is simple thanks to the built-in V REF - PW. ROH H-bridge PW drivers deliver precise control, high efficiency and low power consumption. Direct PW control signal input PW pulses from an external CU can be used to control motor speed. Inputs are TTL compatible. Low power consumption Using PW control, the power dissipation of the IC is vastly improved over linear control, removing the requirements for heatsinks in many applications. Internal shoot-through current prevention Overlap current during motor breaking or reversal is completely eliminated without the use of external components, resulting in improved reliability and increased energy savings. Complementary OSFET output stage The COS output stages eliminate the need for a charge pump and external capacitors to operate the high side driver. Components in the application are minimized. Enhanced protection Four protection s are provided to ensure high reliability: Overcurrent Protection (), Overvoltage Protection (), Thermal Shut Down () and Undervoltage Lock Out (). Power saving This turns off all other internal s during standby mode reducing the standby current to virtually zero. 4kV ESD voltage Protection from ESD voltage of up to 4 kv Human Body odel (HB) has been achieved through optimization of processes and ry, ensuring high reliability in any environment. Independent control for each channel For 2-Channel models, the overcurrent protection in each channel utilizes independent control. Symetrical pin layout eliminates 180 rotational mismounting. Complete lineup ROH s lineup of H-bridge drivers offers a wide selection of supply voltages, output currents, single and dual channels in pin-compatible package configurations.
