L298HN FAQs
1.Q: Is the L298HN compliant with industry standards like RoHS?
A: No, the datasheet indicates it’s not compliant with Reach/ROHS standards (ECCN: EAR99). Check STMicroelectronics for alternate compliant parts.
2.Q: What are the output characteristics of the L298HN?
A: The outputs are totem-pole (push-pull) with true polarity, capable of sourcing and sinking 2A per channel.
3.Q: What is the package type and material of the L298HN?
A: It uses a Multiwatt-15 package (RECTANGULAR, through-hole) with ceramic/metal-sealed body and matte tin-plated leads.
4.Q: Does the L298HN have built-in protection features?
A: Yes, it includes over-current protection but lacks thermal shutdown. External heat sinking may be required for high-load conditions.
5.Q: What is the maximum supply voltage (VS) for the L298HN?
A: The absolute maximum supply voltage (VS) is 46V, while the recommended operating range is 4.8V to 42V. The logic supply (VSS) ranges from 4.5V to 7V.
6.Q: What are the typical applications for the L298HN driver?
A: It’s commonly used in DC/stepper motor control, robotics, industrial automation, and automotive systems requiring bidirectional motor driving up to 2A.
7.Q: What is the pinout configuration of the L298HN in Multiwatt-15 package?
A: The L298HN has 15 pins in a Multiwatt-15 (horizontal, bent/staggered leads) package. Pins include dual bridge inputs/outputs (IN1/IN2, OUT1/OUT2, etc.), enable controls, and power supply connections (VS, VSS).
8.Q: What are the key features of the STMicroelectronics L298HN motor driver?
A: The L298HN is a dual full-bridge driver with low noise (15mW), 4 outputs, and 2A current capability per channel. It includes built-in over-current protection, operates from 4.5V to 7V logic supply, and supports source/sink output direction.
