Datasheet - Pan186cv

While not optimized like a dedicated comparator (e.g., LM311), the PAN186CV can function as a slow comparator in non-critical applications. Connect a reference voltage to IN- and the signal to IN+. The output will swing to V+ or V- based on the input difference.

The PAN186CV datasheet includes timing diagrams that illustrate transitions between states:

Pro tip: The datasheet often has a small note: “When the battery is over-discharged, the IC consumes <0.1µA, preventing deep discharge damage.” This is a key selling point for self-discharge-sensitive applications.

The heart of the PAN186CV datasheet is the electrical characteristics table. For a 3.7V Li-ion cell, expect these values at 25°C: pan186cv datasheet

Interpretation: The delay times are critical for system stability. If your load has large inrush current (e.g., a motor or RF amplifier), the default 10ms overcurrent delay might be too short. Some variants allow external capacitor adjustment of these timers – check your specific datasheet.

If your circuit isn’t working, the PAN186CV datasheet provides a flowchart for failure analysis:

| 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. | While not optimized like a dedicated comparator (e

Why choose the PAN186CV over others? The PAN186CV datasheet highlights low quiescent current and precise voltage thresholds. However, consider these alternatives:

| 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 |

If your project is battery-life critical, the PAN186CV’s 3µA typical current is competitive. Always check the datasheet for your specific voltage option (CV may indicate 4.30V version). Pro tip: The datasheet often has a small

A: Yes, but you must bias the non-inverting input to half the supply voltage (Vcc/2) using a voltage divider. Also, ensure the input common-mode range includes the bias voltage.

Other suffixes might include: CJ (ceramic DIP), M (SOIC surface mount).

At the heart of the PAN186CV is the Texas Instruments CC1101 low-power sub-1 GHz transceiver chip. This chipset is widely respected in the industry for its high sensitivity and robustness against interference.
