# SLM6500S

**SOLA IC** · Battery Management · SOP-8-EP

SLM6500S from SOLA IC, in a SOP-8-EP. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | GND | power_in | Power ground for the charger; the datasheet gives no voltage limit for this pin. |
| 2 | VCC | power_in | Input supply pin, specified at 3.8 V to 6.0 V with 5 V typical and an 8.5 V absolute maximum; the charger enters low-power shutdown when VCC minus BAT is below 30 mV, with BAT current below 2 uA. |
| 3 | NCHRG | output | Open-drain charge-status output that is pulled low while charging (sink up to 5 mA gives V_NCHRG of 0.3 V typ, 0.6 V max) and is high-impedance otherwise; absolute maximum is 8 V. |
| 4 | NSTDBY | output | Open-drain charge-complete output that is pulled low when the battery is fully charged (sink 5 mA gives 0.3 V typ, 0.6 V max) and is high-impedance otherwise; absolute maximum is 8 V. |
| 5 | TS | input | Enable control and battery NTC input: charging is suspended when TS is below 45% or above 80% of VIN, TS tied to VCC disables temperature sensing, and TS tied to GND puts the part in standby with charging terminated; absolute maximum is 8 V. |
| 6 | BAT | power_out | Battery connection that delivers charge current and a 4.2 V regulated limit to the battery (4.2 V ±1%), with leakage below 2 uA when disabled or in sleep mode; absolute maximum is 7 V. |
| 7 | VS | power_in | Positive input of the charge-current sense; the external sense resistor RS between VS and BAT sets IBAT, with 100 mV across RS in constant-current mode; absolute maximum is 7 V. |
| 8 | LX | output | Switch node connected to the internal power MOSFETs and external inductor, serving as the charge-current output to the battery path; absolute maximum is 7 V. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
