Product Highlights:
1. Product industrial design, stable and reliable, with anti-static circuit, transient suppression protection, undervoltage protection, interface ESD and over-voltage protection;
2. Support voltage 9-36V wide range, the maximum sustained load current 12A (without heat), 15A (simple heat), 20A (thick large radiator);
3. similar to L298 drive logic, three lines (PWM, IN1, IN2) control speed, forward and reverse and brake;
4. Support full PWM, can be directly used to control the positive and negative keys, PWM effective range of 0.1% to 100.0%;
5. For the microcontroller and other controllers to provide 5V power supply, and 5V output overcurrent protection, and access signal overvoltage protection.
Control Signal Logic:
Note: 0 is low, 1 is high, × is any level, floating is low.
COM for the signal ground, 5VO 5V output, for the microcontroller and other controllers to provide 5V power supply;
PWM pin external PWM, if the use of key control, PWM pin should be connected with the 5VO;
IN1 and IN2 for the two motor positive and negative turn, brake control signal.IN1 IN2 PWM OUT1、OUT2 Output 0 0 × brake 1 1 × float 1 0 1 Full speed 0 1 1 Full speed reversal 1 0 PWM Forward speed 0 1 PWM Return speed Product Parameters:
1. Power supply voltage 6V-36V (voltage is too low, large load current easily lead to damage to the module, so the circuit board labeled 9-36V),
the power must not be reversed or more than 37V, or may burn the module, it is recommended that the power Input in series 20A fuse.
2. Drives without heat sink rated current 12A, rated current 12A ~ 15A need to do simple cooling, 15A ~ 20A need to do thick heat sink.
(simple cooling - such as in the module below a 1mm thick thermal insulation silicone pad, and then 5mm copper column to the module fixed to the wall)
3. Control signal interface (orange) can provide users with external 5V, microcontroller no additional power supply, the maximum supply current 0.5A.
4. Control signal high voltage: 2.0V ~ 5.5V, compatible with 3.3V and 5V TTL level;
Control signal low voltage: 0V ~ 0.8V, 0V when floating;
When the control signal voltage is 5V, the control signal current is 50uA.
5. PWM effective range: 0.1% ~ 100.0%;
PWM signal frequency range: 0 ~ 100KHz (recommended 20KHz);
PWM minimum effective pulse width: 200ns.
6. Operating temperature -25 ℃ -80 ℃.
7. Product Size: 55 * 55 * 25mm (length and width).
8. Mounting hole diameter: 3mm.
9. Weight: 38g.
