Replacement Options for U1
Recommend a replacement for @U1.
Thought for 3 mins 31 sec
Here are solid replacements for U1 (Texas Instruments DRV8833PW, dual H-bridge):
Recommended drop‑ins (same package/pinout)
- DRV8833PWR — Same device in 16‑TSSOP; “PWR” is tape‑and‑reel. Electrical specs match DRV8833PW.
- DRV8833CPWPR — TI “C” revision in 16‑TSSOP; commonly used as a direct substitute in the same footprint.
Functionally similar (not pin‑compatible; layout/controls change required)
- TB6612FNG — Dual H‑bridge motor driver in SSOP‑24.
Key DRV8833 datasheet limits to match
- VM motor supply: 2.7 to 10.8 V (Recommended operating conditions).
- Continuous output current per bridge: 1.5 A (RMS/DC).
- Overcurrent trip: 2 to 3.3 A. Per datasheet: https://www.ti.com/lit/ds/symlink/drv8833.pdf
Best practice
- Prefer drop‑in replacements first. For power ICs, target no more than 75% of rated current/power in your application.
Pick drop-in PWR
Pick C revision
Check electrical margins
