| Part Number | Quiescent Current | Overcharge (V) | Package | Advantage | |-------------|------------------|----------------|---------|------------| | PAN186CV | 3µA | 4.30 ±0.025 | SOT-23-6 | Low cost, widely available | | DW01A | 5µA | 4.30 ±0.05 | SOT-23-6 | Very common, easy to source | | AP9101C | 4µA | 4.35 ±0.025 | DFN-6 | Smaller footprint for wearables | | FS312F | 2.5µA | 4.28 ±0.02 | SOT-23-6 | Lower quiescent current |
| Symptom | Likely Cause | Datasheet Solution | |---------|--------------|--------------------| | No output voltage | DO pin low | Check if battery is <2.4V (overdischarge). Apply charger. | | Output always on (no protection) | Short at CO or DO pin | Inspect solder bridges. Check if FETs are reversed. | | False overcurrent trips | VM pin noise | Add a 100pF cap from VM to VSS. Confirm R2 is present. | | IC hot / smoking | VDD overvoltage | Input >10V? Add a Zener diode (9.1V) clamp. | Why choose the PAN186CV over others? The PAN186CV datasheet highlights low quiescent current and precise voltage thresholds. However, consider these alternatives: pan186cv datasheet
This article serves as a comprehensive guide to the . We will cover its typical specifications, pinout, electrical characteristics, application circuits, and best practices for sourcing and interpreting this critical document. Note: As of this writing, the PAN186CV is commonly identified as a Lithium-ion or Li-Polymer battery protection IC, or a load switch. Always verify with the manufacturer’s latest revision. What is the PAN186CV? The PAN186CV is typically a one-cell lithium-ion/polymer battery protection IC integrated into a compact SOT-23-6 or similar small-outline package. It is designed to prevent battery damage by monitoring overcharge, over-discharge, overcurrent, and short-circuit conditions. The "CV" suffix often denotes a specific voltage threshold or a version with a built-in regulator or delay timing. | Part Number | Quiescent Current | Overcharge
