SLM6150 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 | TEMP | input | Battery temperature sense input for the NTC sensor; charging is suspended if its voltage is below 45% or above 80% of VCC, and the function is disabled by grounding the pin. |
| 2 | PROG | bidirectional | Charge current setting and monitor pin; a resistor RPROG to GND programs the current (IBAT=VPROG/RPROG*1330), with PROG regulated to 0.1V in pre-charge and 1V in constant-current mode. |
| 3 | GND | power_in | Ground. |
| 4 | VCC | power_in | Positive input supply voltage (4.0V to 8.0V operating) powering the internal circuit; the device enters low power mode when VCC drops within 30mV of the BAT voltage. |
| 5 | BAT | power_out | Battery connection pin providing charge current and 4.2V regulation voltage, with BAT current below 2uA in disable or sleep mode. |
| 6 | STDBY | output | Open-drain charge terminated status output that is pulled low by an internal switch when charging terminates and is otherwise high impedance (rated -0.3V to 10V). |
| 7 | CHRG | output | Open-drain charge status output that is pulled low by an internal switch while the battery is charging and is otherwise high impedance (rated -0.3V to 10V). |
| 8 | CE | input | Chip enable input where a high level (above 1.2V) selects normal operation and a low level (below 0.6V) puts the device in disable mode, driven by TTL or CMOS logic. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
