Module one-channel H bridge VNH3SP30 ST lets you control the motors with a supply voltage in range 5.5 V - 24 V continuous drain current up to 12 A, for short periods up to 30 A. the System allows you to change the motor rotation direction and speed control through a PWM signal.
The minimum number of connections of the module VNH5019 with a microcontroller.
The input PWM signal pulled up to the masses. The power outputs of the engines, so they are blocked by default. On the Findings of controlling the direction of rotation INA, MOS was not installed by default, no potential.
The LEDs located on the Board, they are very useful for discovering problems with the connection. The brightness increases with the rotational speed of the engine, and the color changes with the direction of rotation.
|VIN||The 24 V Supply|
|VDD||Power logic 2.5 V to 5 V|
|VOUT||Output voltage protection against reverse power connection.|
|OUT||The output of half-bridge And power engines|
|OUTB||Output half-bridge B power engines|
|PWM||The input of the PWM signal by default pulled to ground (to 20 kHz)|
|INA/MOP||Zone changes direction of rotation. Default not active.|
|CS||The output of the current measurement. 140mV at 1A. Active when PIN CS_DIS low.|
|ENA/DIAGA||Blocking half-bridge A. low blocks the action of half-bridge A. the Default high state.|
|ENB/DIAGB||Blocking half of the sternum B. at the same time blocks the action of half of the sternum B. Default in the high state.|
|CS_DIS||Lock output current measurement. High blocks the release of CS. Default in the low state.|
