FM2117L from Shenzhen Fuman, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DOUT | output | Discharge control output. Connects to the gate (G) of the external discharge control N-MOS transistor Q2. Outputs high (~VDD) in normal state and low (VSS level) when in over-discharge/over-current/short-circuit protection to turn Q2 off. |
| 2 | VM | input | Charge/discharge current sense input. Connects through a current-limit resistor (typ. 1 kΩ, 2.2 kΩ shown in Fig.3) to the source (S) of external charge-control N-MOS Q1 to sense the voltage drop across Q1+Q2 during charge/discharge. Used for charger detection (VCHG), over-current discharge (VEDI) and battery short (VSHORT) detection. |
| 3 | COUT | output | Charge control output. Connects to the gate (G) of the external charge control N-MOS transistor Q1. Outputs high (~VDD) in normal state and low (VM level) during over-voltage charge protection to turn Q1 off. |
| 4 | NC | unconnected | No connection. Pin is left floating (悬空). |
| 5 | VDD | power_in | Power supply input. Connect to the positive terminal of the battery through a series resistor R1 (typ. 330 Ω). Requires a 0.1 μF ceramic decoupling capacitor to VSS. Absolute maximum -0.3 V to +10 V; operating range 1.5 V to 10 V. |
| 6 | VSS | power_in | Ground / power return. Connect to the negative terminal of the battery. Reference for all internal voltage thresholds. |
