L298 h-bridge dual bidirectional motor driver (2 x 2a) this dual bidirectional motor berada di home driver motor driver motor dc 15a mosfet dual h-bridge. Share sedikit tentang rangkaian driver motor h-bridge dengan. L293 is quadruple half-H driver and L298 is dual full-H driver. In L293 all four input- output lines are independent, while in L298, a half H driver cannot be used independently, full H driver has to be used. Output current per channel is 1A for L293 and 2A for L298. Hence, the reason for heat sink. L298 - Dual Full-Bridge Driver The L298 is an integrated monolithic circuit in a 15-lead Multiwatt and PowerSO20 packages. It is a high voltage, high current dual full-bridge driver designed to accept standard TTL logic levels and drive inductive loads such as relays, solenoids, DC and stepping motors.

Usage:
H-Bridge's are typically used in controlling motors speed and direction, but can be used for other projects such as driving the brightness of certain lighting projects such as high powered LED arrays.

An H-Bridge is a circuit that can drive a current in either polarity and be controlled by *Pulse Width Modulation (PWM).

* Pulse Width Modulation is a means in controlling the duration of an electronic pulse. In motors try to imagine the brush as a water wheel and electrons as a the flowing droplets of water. The voltage would be the water flowing over the wheel at a constant rate, the more water flowing the higher the voltage. Motors are rated at certain voltages and can be damaged if the voltage is applied to heavily or if it is dropped quickly to slow the motor down. Thus PWM. Take the water wheel analogy and think of the water hitting it in pulses but at a constant flow. The longer the pulses the faster the wheel will turn, the shorter the pulses, the slower the water wheel will turn. Motors will last much longer and be more reliable if controlled through PWM.
