MD02 motor drive 17A H bridge Super L298N BTS7971
MD02 motor drive 17A H-bridge current detection Super L298N BTS7971 Freescale smart car
L298
Operating voltage: 5.9-40V
Working current: 17A
Logic input: 1.8V, 3.3V, 5V (max)
PWM frequency: 100kHz
Current Detection: 50mV/A CS Pin
Reverse Voltage Protection: None (VM and GND must not be reversed)
Undervoltage protection: Yes
Short circuit protection: Yes
Pin Default Status Description
VM power input, voltage range 5.9-30V(max)
MA1 motor output wiring positive
MA2 motor output wiring negative
Connect GND to negative power supply
PWMA low-level motor speed PWM signal input, can realize motor speed adjustment
DIRA Low level motor direction control. When high, current flows from M+ to M-, and vice versa from M- to M+.
SLP low-power mode, default low level, need to keep SLP pin high
The CSA current detection pin is only valid for positive and negative reversal. The output voltage is proportional to the current (50mV/A) and the voltage is 0.05V when the current is zero.
