FM5327 from Shenzhen Fuman, in a ESOP-8L. 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 | VIN | power_in | Power supply input; recommended operating range 4.75 |
| 2 | DCP | output | USB DCP output pin for automatic D+ and D- switching in Apple, Samsung, and BC1.2 fast charging protocols with 2.7V output on both D+ and D- lines |
| 3 | KEY | bidirectional | Pushbutton key input and NTC thermistor sense current output; outputs 20uA constant current source for battery temperature monitoring using 100kΩ NTC thermistor with 82kΩ parallel adjustment resistor |
| 4 | LED1 | output | LED indicator driver output 1; drives LED indicators in 1-4 LED or 2-LED battery state-of-charge display modes with 1Hz or 2Hz blinking patterns |
| 5 | LED2 | output | LED indicator driver output 2; drives LED indicators in 1-4 LED or 2-LED battery state-of-charge display modes with 1Hz or 2Hz blinking patterns |
| 6 | BAT | bidirectional | Battery positive terminal detect and charging current source pin; monitors battery voltage range 2.7~4.4 V and provides charging current up to 2.2 A with three-stage charging (trickle/constant current/constant voltage) and adjustable float voltage 4.2V or 4.35V |
| 7 | SW | output | Synchronous boost converter inductor drive output and power MOSFET drain pin; switches at 1000 kHz for boost mode and 500 kHz for charging mode with soft-start control |
| 8 | OUT | output | Regulated power output pin for external load; provides 5V boost output up to 2.4A with no-load voltage 5.1V, output overcurrent protection threshold 4.2V, and short-circuit protection with 1s recovery delay |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
