TP1941-TR C4TG8 Voltage Comparator for Whatsminer P221C PSU
Upgrade and replace the voltage comparator chip in your Whatsminer P221C power supply with the TP1941-TR C4TG8. This high-performance chip features a fast response time and low-power operation — ensuring optimal performance and reliability for your PSU repair.
The TP1941-TR is a voltage comparator designed for low-power 1.8V single-supply applications — ideal for the Whatsminer P221C control loop. Higher input operation and rail-to-rail output swing provide precise and efficient voltage comparison for switching control feedback.
Typical Use in Whatsminer P221C Repair
Failed comparator replacement — restoring control loop voltage threshold detection.
Hot-failure recovery — replacing parts damaged in thermal events.
Production refurbishment — bulk comparator stock for P221C rebuild lines.

FAQ — TP1941-TR Voltage Comparator
Q: How do I diagnose a failed comparator? A: Typical signs: PSU output oscillation, incorrect threshold detection, no switching control signal at expected pin. Probe Vout with oscilloscope to verify expected switching pattern.
Q: Can I substitute another comparator? A: For OEM-spec P221C repair, stick with TP1941-TR. Pin-compatible substitutes with matching electrical envelope may work but require verification.
