Its name derives from the fact that that switching transistors are designed in an 'H' configuration. Mainly used for forward and reverse control in DC motors, it can also be found in latching relay drive circuits. Other names include bridge driver and reversible motor driver.

CMOS output (complementary output) normally consists of a Pch MOS at the high output stage and an Nch MOS at the low output stage. An alternative configuration is NMOS output, comprised of Nch MOSFETs at both high and low sides. However, the high side Nch MOSFET requires a step-up voltage source for driving, such as a charge pump or bootstrap circuit, which necessitates an external capacitor.
ROHM's H-bridge drivers are all CMOS type, eliminating the need for additional step-up circuits and external capacitors.

Yes.
PWM signals (to 100KHz) can be directly connected to conventional control input pins, eliminating the need to increase microcontroller ports. Only 2 ports are required for PWM control.

This function allows generation of an arbitrary output voltage based on the reference (V_REF) voltage.

ROHM's H-bridge drivers integrate a circuit that prevents through current flow (also referred to as an output simultaneous ON prevention circuit). The result is greater efficiency and reliability.

No time is required.
Conventional products, due to the through-current that flows during switching from forward to reverse and vice versa, often require time to go into brake or standby mode. ROHM's H-bridge drivers, however, prevent through-current flow, resulting in no wait time.

No.
Unless there exists the possibility of exceeding the absolute maximum ratings of the driver IC, physical countermeasures, such as a Zener diode for clamping, are unnecessary.

On a brush DC motor is a brush that supplies current to the commutator.

A brush motor is an older motor type.
In order to combat friction and noise, the brush and commutator were replaced by semiconductor elements (e.g. Hall), resulting in 'brushless' motors.

When driving a motor using pulse control the applied voltage is relatively high, resulting in better efficiency.

Connecting an output current detection resistor is not recommended.
