4 verified alternatives for L298N
| Alternative | Manufacturer | Relationship | Key differences | Source |
|---|---|---|---|---|
| L298P | STMicroelectronics | FunctionalSame function: board or design change needed. | Same L298 dual full-bridge function in PowerSO-20 (SMD) instead of Multiwatt-15 (through-hole) - a PCB redesign is required. Both belong to the 46 V / 4 A-total L298 family per ST's product page. | ST 官方页面 |
| L293D | STMicroelectronics | FunctionalSame function: board or design change needed. | Smaller sibling: quad half-bridge (usable as two full bridges), 600 mA per channel / 1.2 A peak, up to 36 V (vs 46 V / 2 A per channel for L298N), with internal clamp diodes so no external flyback diodes are needed. DIP-16 or SOIC-20 - a different footprint and not suitable for high-voltage or high-current L298N designs. | ST 官方页面 |
| TB6612FNG | Toshiba | FunctionalSame function: board or design change needed. | Modern MOSFET dual H-bridge: 1.2 A average / 3.2 A peak per channel, very low voltage drop, internal thermal shutdown. Differences: motor supply limited to about 13.5 V operating (15 V absolute max) - cannot replace L298N in 24-46 V systems; SSOP-24 footprint; 2.7-5.5 V logic; different control pins - full redesign needed. | Toshiba 官方页面 |
| DRV8833 | Texas Instruments | FunctionalSame function: board or design change needed. | Dual H-bridge MOSFET driver with current regulation, nFAULT diagnostics, and sleep mode: 1.5 A RMS per channel (PWP/RTY packages). Differences: 2.7-10.8 V only (cannot replace L298N above 10.8 V), HTSSOP/QFN footprints, different control scheme. Note: the DRV8833PW variant is marked obsolete on TI - choose RTY or PWR. | TI 官方数据手册 |
Pre-replacement checklist
- Confirm the motor supply voltage: L298N runs up to 46 V - TB6612FNG (about 15 V) and DRV8833 (10.8 V) cannot replace it in high-voltage designs.
- Check current per channel: L298N handles 2 A per bridge; size the replacement's current rating and heatsinking.
- Plan for a new footprint and control wiring - none of these are pin-compatible with Multiwatt-15.
- L298N needs external flyback diodes; L293D has internal diodes and the MOSFET drivers have internal protection.
