L293D Vs. L298N: What’s The Difference?

The L293D is a 16-pin Motor Driver IC that can operate two DC motors in any direction at the same time. The L293D is capable of bidirectional drive currents of up to 600 mA (per channel) at voltages ranging from 4.5 V to 36 V (at pin 8!). It can be used to control small dc motors, such as toy motors. It can get exceedingly hot at times.

The L298N is a 15-lead Multiwatt and PowerSO20 integrated monolithic circuit. It is a high voltage, high current dual full-bridge driver that accepts conventional TTL logic levels and drives inductive loads like as relays, solenoids, DC and stepping motors. There are two enable inputs to enable or disable the device independently of the input signals. The emitters of each bridge's bottom transistors are connected together, and the matching external terminal can be used to connect an external sensing resistor. A second Supply input is supplied so that the logic can operate at a lower voltage.

1. 4.5 V to 36 V supply voltage range

2. Separate Logic-Input Supply

3. High-Noise-Immunity Inputs Internal ESD Protection

4. 600 mA per channel output current

5. Peak Output Current 1.2 A Per Channel Temperature range: 0°C to 70°C for clamp diodes for inductive transient suppression.

6. There is an option for automatic thermal shutdown.

1. The operating supply voltage might be as high as 46 V.

2. Total DC current of up to 4 A per channel

3. Saturation voltage is low.

4. Protection against overheating

5. Up to 1.5 V logical input voltage

6. Noise immunity is excellent.

1. L293D drivers operate between 4.5V and 36V, but L298N drivers can operate between 4.5V and 46V.

2. The L293D Motor Driver can draw up to 600mA from both channels, whereas the L298N Motor Driver can draw up to 2A from both channels.

3. L293D is a quadruple motor driver that employs a half-H driver, whereas L298N is a dual full-H driver, which means that in L293D all four input-output lines are independent, whereas in L298N a half-H driver cannot be utilized separately, and only a full H driver may be used.

4. L293D output current for each channel is 650mA, whereas L298N output current is 2A. As a result, the heat sink is included in L298N motor drivers.

5. Internally, EMFs are delivered in L293D, but must be provided externally in L298N.

6. L293D is appropriate for small current drawing motors such as BO motors, DC geared motors up to 500 RPM, and small stepper motors that demand less current up to 600mA at their maximum torque rating. Whereas L298N has a greater output current of up to 2A, making it appropriate for high torque and high RPM motors such as Johnson motors and high torque DC Geared mot

7. The L293D motor driver IC is breadboard compatible, however the L298N motor driver IC cannot be used on a breadboard.
