The TB6612FNG driver can control a stepper motor or up to 2 direct current motors.
Its internal structure is based on LD MOS technology, which means that it has a very small internal resistance and therefore can handle a large amount of current in a very small space.
Accepts PWM signals up to 100kHz.
Its control pins accept a minimum voltage of 2.7V and a maximum of 5.5V.
It has internal protection diodes so it is not necessary to implement them externally.
Supports 1.2A average consumption or 3.2A peaks (10ms)
TB6612 Dual Driver Minimum System
Maximum voltage: 15V
