H-bridge Drivers
from ROHM Semiconductor
DC brush motors are simple, reliable and low-
control from an external MCU or other motor
The ROHM H-bridge drive product line is
cost. And now, to achieve the best possible
control device.
offered with pin-compatible devices optimized
performance and design flexibility, ROHM
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 PWM motor
speed control output. These powerful new
ROHM H-bridge ICs combine BiCMOS
control and power MOSFET outputs to deliver
exceptional performance with minimal external
for 7 V, 18 V and 36 V maximum supply
voltages to optimize power consumption; and
in single and dual channel configurations.

The FIN and RIN also provide a TTL-compatible
interface to an MCU or other external PWM
control device.
High efficiency drive
CMOS output
ROHM’s P-Channel / N-Channel high-power
CMOS 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.

Whether operated via an external MCU
or with the ICs’ internal VREF to PWM

controlled.
Enhanced Protection Circuitry
Built-in protection circuits such as TSD (thermal
shut down), OCP (overcurrent protection), OVP
(overvoltage protection), and UVLO (undervoltage
lock out) assure system reliability.

Power saving
n 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 MOSFET output stage
n The CMOS output stages eliminate the need for a charge pump and external capacitors to operate
the high side driver. Components in the application circuit are minimized.
Enhanced protection circuit
n Four protection circuits are provided to ensure high reliability: Overcurrent Protection (OCP),
Overvoltage Protection (OVP), Thermal Shut Down (TSD) and Undervoltage Lock Out (UVLO).
Power saving circuit
n This circuit turns off all other internal circuits during standby mode reducing the standby current to
virtually zero.
