无锡松朗微 · Battery Management · ESOP-8
SLM6705 from 无锡松朗微, in a ESOP-8. 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 | VIN | power_in | Input supply voltage pin; the absolute maximum rating is -0.3V to 22V. |
| 2 | NCHRG | output | Charge status indicator that is pulled low by an internal switch while the charger is charging the battery and is otherwise high-impedance; absolute maximum rating is -0.3V to VIN+0.3V. |
| 3 | NACOK | output | Power status indicator that is pulled low by an internal switch when VIN is above the battery voltage and above the undervoltage threshold, and is otherwise high-impedance; absolute maximum rating is -0.3V to VIN+0.3V. |
| 4 | NTC | input | Battery temperature sense input for a negative-temperature-coefficient thermistor, where charging is turned off if the battery temperature is too high or too low; if unused it may be left floating or connected to GND through 10kΩ, and the absolute maximum rating is -0.3V to 6.5V. |
| 5 | BAT | input | Battery voltage sense input connected to the positive terminal of the battery for real-time voltage monitoring; absolute maximum rating is -0.3V to 20V. |
| 6 | VS | power_in | Charge current sense input, where a high-precision resistor is connected between VS and BAT to monitor charge current; absolute maximum rating is -0.3V to 20V. |
| 7 | BST | passive | Bootstrap pin for the internal high-side power switch drive, with a small capacitor connected between BST and LX; absolute maximum rating is LX-0.3V to LX+5.5V. |
| 8 | LX | output | Switching output node connected to the external inductor that delivers the charging current; absolute maximum rating is -0.3V to VIN+0.3V. |
| 9 | GND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
